Specifications

Nominal Input    Operating Input Voltage Range
-------------------------------------------------
 24 Vdc           18-36 Vdc (or 18-75 Vdc)
 48 Vdc           36-75 Vdc (or 18-75 Vdc)
 72 Vdc           36-75 Vdc (or 18-75 Vdc)
125 Vdc          110-350 Vdc
250 Vdc          110-350 Vdc

Input Reverse Polarity Protection: Internal shunt diode (external fuse required).

Startup Time: 800 mS typical.

Load Regulation: ±0.05%
Line Regulation: ±0.05%

Output Voltage Remote Adjustment: The output voltage may be controlled by means of an external 1K potentiometer.

Polarity: Output is floating and may be used in either polarity.

Drift: ±0.1% maximum over 8 hours, after 30 minute warmup.

Temperature Coefficient: ±0.02%/°C (Typical).

Transient Response: 3 ms to return to ±1% of output setting. Maximum of ±3% output excursion following a load step change from 50% to 100%.

Remote Sensing: Compensates up to 0.5 volt drop per output line, within the limits of the output voltage adjustment range.

Overload/Short Circuit Protection: Current limiting with automatic recovery.

Overvoltage Protection:
Case sizes DN6A, DN6B: automatic reset.
Case sizes DN8, DN8A: latches power supply OFF, reset by momentarily removing DC input power.

Output Inhibit (DN8 and DN8A case sizes only):
Applying between +3 and +25 Vdc (relative to the -Out terminal) to the inhibit terminal will disable the supply.

EMI: Designed to meet FCC Part 15 and EN55022, Class A.

Output Indicator (DC out): Green LED.

Thermal Protection:
Case sizes DN8, DN8A, DN6A: thermostat, self-resetting.
Case size DN6B: inherently protected.

Efficiency: (Typical, at nominal input voltage, with full load.) 65 to 80%

Ambient Operating Temperature: 0 to +71°C.

Storage Temperature: –40 to +85°C.

Cooling: Case sizes DN8, DN8A, DN6A: forced air cooled; air enters rear of power supply and exits from top.
Case size DN6B: convection cooled.

Switching Frequency: 100 kHz (Typical).
