SPECIFICATIONS: PSPW500 Series

All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.

We reserve the right to change specifications based on technological advances.

INPUT SPECIFICATIONS

Input Voltage Range

90 ~ 264VAC (Full Range)

Input Frequency

47 ~ 63Hz

Input Current (rms)

6A max. at 115VAC; 3A max. at 230VAC

Inrush Current

< 25A peak at 115VAC; < 50A peak at 230VAC

cold start and 25°C

Power Factor

>0.95 at 115VAC and full load; > 0.90 at 230VAC and full load

Hold Up Time

20ms typ. at 360W load and 115VAC input

Overshoot at Turn-On/Turn-Off

< ±10% of nominal output voltage.

No voltage of opposite polarity should be present on the output during turn-on or turn-off

Temperature Coefficient

±0.04%/°C

ADDITIONAL FUNCTIONS

Active Low

0 – 0.5V (output is disabled)

Remote Control (Inhibit)

Active High or Floating

3.5 – 5.25V (output is enabled)

Active Low

Output voltage falls below its under voltage threshold.

Power Good Output

Active High

Indicates DC output is good and within regulation

Active Low

Fan fault

Fan Fault Output

Active High

Fan works in normal condition

Fan Speed Control

The power supply includes a sophisticated fan controller that only turns the fan on as needed, sets the fan

speed according to cooling requirements, and generates a fan fail alarm for a non-rotating fan.

Single wire: Up to 4 units cane be paralleled within 10% accuracy at full load

PROTECTION

Short Circuit Protection

The supply will automatically recover without damage when short circuit condition is removed.

Over Voltage Protection

110% to 130% above nominal output. The power supply will not automatically recover after the fault

condition is removed. A manual reset is necessary or INHIBIT pin is reset.

Over Load Protection

110% to 150% maximum load. Auto-recovery without damage after fault condition is removed.

Over Temperature Protection

An over temperature condition is typically the result of current overloading or inadequate air circulation.

When the thermistor senses a temperature inside the power supply that is above normal, the unit will

automatically shut down. The power supply will recover when the thermistor temperature returns to a normal

value and after the INHIBIT pin is reset.
