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:

ReservePower will deliver up to 25% additional current continuously.

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

Example:

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

Solution: 1606-XLS120E

Output Characteristic for XLS120E (5 A) Power Supply

IRATED: 5 A ISHORT CIRCUIT: >9 A IPOWER BOOST: 7.5 A

∆  Short circuit current values are temperature dependent for the selected product; i.e., the higher the ambient temperature, the lower the short circuit current.
◆  Hiccup Overload design.

"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).

Application Information

1606-XL Redundancy Capabilities

The 1606-XL family has two cost effective methods for providing redundancy to applications that are critical and can not risk failure.

1606-XL60DR, XL120DR and XL240DR Redundant Power Supplies


The 1606-XL60DR, XL120DR and XL240DR are enhanced versions of the standard power supplies.

• Each device has internal diodes which provide isolation against DC bus problems corrupting working supplies.
  
• Provides "DC OK" output relay to allow remote monitoring of DC power status.
  
• Utilizes pluggable terminals for easy installation.

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.
