DESCRIPTION
The PSM500 series of medical AC/DC switching power supplies consists of U-chassis (U type), enclosed with
rear-side built-in (E type), and enclosed with top-side built-in fan (F type) models. Built-in fan models offer
500W of output power and U-chassis models offer 360W of output power with convection cooling and 500W
with 30CFM forced airflow. All units have a single output, 90~264VAC full range input, and active PFC. These
supplies also have UL60601-1, TUV EN60601-1, and IEC60601-1:2005 (3rd edition) safety approvals. All models
are protected against short circuit, over load, over voltage, and over temperature conditions. This series also
has a current sharing option (suffix “D”).

Fan fault
Fan works in normal condition
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
The supply will automatically recover without damage when short circuit condition is removed.
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.
110% to 150% maximum load. Auto-recovery without damage after fault condition is removed.
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.

NOTES
1. Mechanical Options: The “U” suffix in the model number is for U-chassis type, “E” is for enclosed type with rear-side built-in fan, “F”
is for enclosed type with top-side built-in fan, and the “D” is for current sharing option.
2. U Type: 360W max. at +40°C ambient temp. and free air convection. 500W max. at +50°C ambient temp. and 30CFM forced air.
E Type: 500W max. at +50°C ambient temperature.
F Type: 500W max. at +50°C ambient temperature.
3. +5VSB/0.25A with convection cooling and +5VSB/1A with forced air cooling.
4. Ripple & Noise is measured at 20MHz bandwidth and with 0.1µF ceramic capacitor and 10µF/50V electrolytic capacitor bypassed at
the output connector at 5% to 100% full load and nominal line.
5. Preset accuracy should be less than 1% of nominal output voltage at 60% full load.
