How to Select a Bulletin 1606 Power Supply

The Bulletin 1606 line of Power Supplies is designed with "reserve power" thereby eliminating the need to oversize your power supply to start high inrush loads.

Steps to size a Power Supply

1. Determine the "Average" continuous current of the load and the typical inrush current.

2. Select a power supply where the rated load is at/or below the current of the device and the Peak Current is less than the short-circuit rating of the power supply.

Notes:

PowerBoost will deliver up to 25% additional current continuously at 40 °C or less.

ReservePower will deliver 150% of rated current for up to 5 s.

Example:

Application: Single Phase 120V input, 24V output, 5 A continuous current @ 35 °C, with 7.5 A inrush current

Solution: 1606-XLS120E

Output Characteristic for XLS120E (5 A) Power Supply

z Because this catalog number ends with "C", it indicates the device has conformal coating.

"Shut Down" Input

Function: Turning the unit on or off using logic signal (remote monitoring).
Unit switches off when Input is connected to "Signal GND" terminal (DU £ 1V) or the input has a voltage of +20...28V with respect to the "Signal GND" terminal, (max. 20 mA).

"DC Ok" Output

Function: Indicating whether the unit is operating properly. Output can directly energize a relay or a control light.
Signaling: Output signal is at a "high" level (24V, current source) in normal operation (no overload, overheating, short circuit). When the output signal switches to "low" level (no power at output), Vout remains for 5 ms (nominal) at nominal load.
Connection (signal common): Connection is made with respect to the "Signal GND" terminal (signal output).
Important: Do not connect to the power output (terminals + and -).

Permissible load: resistance - min. 300 W, e.g. 24V relay, control lights (LEDs need no series resistance), Evaluation logic.
For 5V signal: In order to receive a 5V signal: switch a 5V Zener diode (0.5 W) and 1 kW resistance in parallel between this output and the "Signal GND" terminal.

"Thermal Alarm" Output

Function: Output gives warning shortly before and while overtemperature state occurs. Output can directly control a relay or a control light.
Signaling: Output signal is at a "high" level (24V, current source) in normal operation (no overtemperature). At overtemperature, the output switches to "low". Only when the temperature in the unit increases further will the unit reduce its output current (power output).
Connection and permissible load: same as for "DC ok" output.

"Current Monitor" Output

Function: Measuring the output current (power output). Output signal is proportional to the output current of the unit.
Connection: Made with respect to the "Signal GND" terminal (signal output).
Important: Do not connect to the power output (terminals + and -).
Signaling:
Voltage measuring: Voltage at signal output is 1V per 10 A output current (Ri(voltmeter) > 100 k ohm )
Current measurement: Current at signal output is 1 mA per 10 A output current (Ri(ammeter) < 100 W)

"Current Balance" In-/Output

Function: Using these terminals, parallel operating units ensure an equal load sharing (active balancing). Balancing also works reliably with decoupling diodes at the power output (redundancy).

Connection: Connect together "Current Balance" outputs of all units involved.
Important: Signal common here is the - terminal of the power output, not the "Signal GND". Do not connect the "Signal GND" terminals to each other!

"Signal GND" Terminal

Function: Grounding terminal for all signal terminals (not for "Current Balance").
Connection instructions: Do not connect this terminal with terminals + or - of the unit (not even over a load: risk of overload). Do not connect this terminal with terminals of other units (not even with the "Signal GND" terminal of another unit).
Permissible load: Maximum current load: 0.3 A. Terminal is fused internally with a self-healing fuse (polyswitch).

1606-XLBuffer

Features

• Buffering for 24V loads
  
• Guaranteed hold-up time: 0.2 s/20 A…3.6 s/1 A
  
• Fit for industrial use: Energy storage in electrolytic caps., no accumulators
  
• Clear status indication by Status LED and signalling terminals
  
• No batteries requiring replacement
  

Short Description

The buffer unit is a supplementary device for regulated 24V DC power supplies. It buffers load currents during typical mains faults and switching events or load peaks.

Working principle



In times when the power supply provides sufficient voltage, the buffer unit stores energy in integrated electrolytic capacitors. In case of a mains voltage fault, this energy is released again in a regulated process.

Bridges mains faults without interruption



Statistics show that 80% of all mains faults last less than 0.2 s. These mains faults are completely bridged by the buffer unit and will have no influence on the DC power. This increases the reliability of the system as a whole.



Extended hold-up time

Once the main power fails or is switched off, the buffer unit will continue to provide the load current for a defined period of time. Process data can be saved and processes can be terminated before the DC power switches off. Controlled restarts are subsequently possible.

Easy to handle, expandable, and maintenance-free



The buffer unit does not require any control wiring. It can be added in parallel to the load circuit at any given point. Any given number of buffer units can be installed in parallel to increase the output capacity or the hold-up time. The dual terminals allow for easy wiring.

Operating Modes



Activation Threshold

“22.5V fixed”	Buffering starts if terminal voltage <22.5V, voltage is kept at 22.5V.
“Vin -1V”	Buffering starts if terminal voltage decreases by more than 1V, faster than typ. 0.54V/s. Voltage is kept at that level. Buffering ends when voltage increases once more by 1V.
Noise (spikes)	>200mVPP (20MHz bandw., 50 W–measurement, buffer operation only)
Over voltage protection	limited to max. ±35V

1606-XLS DC UPS

Features

• Requires only one 12V battery
  
• Electronically protected against output overloads
  
• Flexible battery options, modular system
  
• Extensive battery management including battery quality and installation tests
  
• Regulated output voltage in buffer mode
  
• Soft charger for optimum battery life
  
• 50% power reserves
  
• Extensive diagnostic and monitoring functions
  

Short Description

The DC UPS is a supplementary device to a 24V power supply. It provides back-up power to bridge dips, sags, or brief losses of power using a 12V battery. Based on the battery you select, you can achieve hold-up times anywhere from a few minutes to several hours.

Working principle

In times when the power supply provides sufficient voltage, the DC UPS charges the 12V battery. When input power fails, the battery voltage will be boosted to a 24V level through a boost converter and the energy will be released in a regulated process to the load.



Integrated in the DC UPS is a sophisticated battery management system. This battery management system incorporates a battery charger, deep discharge protection, and overload protection which together increase the service life of the battery.



In addition, there are extensive protective features that self-protect the unit from damage along with diagnostic and monitoring functions that aid in troubleshooting.



Extended Hold-Up Time

The modular design of the DC UPS allows for flexible battery options. The design will accept valve regulated, lead-acid batteries between 3.9Ah – 27Ah. The modularity of the system enables you to match the battery with your application requirements.



Extensive Diagnostic & Monitoring Functions

Protective Features:

• Wrong battery voltage (24V instead of 12V)
  
• Deep discharge (battery) protection
  
• Wrong battery polarity
  
• Wrong polarity on input terminals
  
• Too high ambient temperature
  
• Over-voltage protection
  (malfunctioning of the internal regulation loops)
  
• Output overload or output short-circuit
  

A - Status LED (green):

• Ready: Battery is charged > 85%, no wiring failure is recognized, input voltage is sufficient and inhibit signal is not active.
  
• Charging: Battery is charging and battery capacity is below 85%.
  
• Buffering: Unit is in buffer mode.
  

B - Diagnosis LED (yellow):

• Overload: Output has switched off, due to long overload in buffer mode or due to high temperatures.
  
• Replace battery: Indicates a battery which failed the battery quality test (SCH test). Battery should be replaced soon.
  
• Buffer time expired: Output has switched off due to settings of buffer time. The signal will be stored and displayed for 15 minutes.
  
• Inhibit active: Indicates that buffering is disabled due to an active inhibit signal.
  

C - Check wiring LED (red):

Check wiring between DC UPS and battery, as well as the battery itself. Also indicates when input voltage is not in range.

D - Adjustor:

• Buffer time limiter: User accessible switch which limits the maximum buffer time in a buffer event, to save battery capacity.
  
• End-of-charge voltage: User accessible potentiometer which sets the end-of-charge voltage. Adjust the potentiometer according to the expected battery temperature.
  

E - Signal contacts:

Ready (contact 1-2):

Contact is closed when battery is charged more than 85%, no wiring failure is recognized, input voltage is sufficient, and inhibit signal is not active.

Buffering (contact 3-4):

Contact is closed when unit is buffering.

Replace battery (contact 5-6):

Contact is closed when input voltage is sufficient and battery quality test (SCH test) indicates a negative result, three times in a row.

Inhibit input (contact 7&8):

The inhibit input disables buffering. In normal mode, a static signal is required. In buffer mode, a pulse with a minimum length of 250 ms is required to stop buffering. The inhibit is stored and can be reset by cycling the input voltage.
