General Notes:

Peak current rating on main output is 120 % of max., lasting < 30 s with a maximum 10 % duty cycle.
Combined output power of main output, fan supply and standby supply shall not exceed max. power rating.
Standby output voltage tolerance including set point accuracy, line and load regulation is +/-10 %. Ripple and noise is less than 5 %.
Fan supply output voltage tolerance including set point accuracy, line and load regulation is +/-30 % and needs min. 1 % load on main output to be within regulation band. Ripple and noise is less than 10 %.
Class II means without input Earth pin. Add -II suffix to order Class II product.
Class II product meets Class A limit line for conducted emission.
Specifications are for nominal input voltage, 25°C unless otherwise stated.
PSU is supplied with J3 housing, pin-1 and pin-2 shorted to enable main output without remote on/off feature.
Derate output power linearly to 80% from 90 VAC to 80 VAC input.
Power good signal cannot be used as a current source. Internal pull up resistor from PG signal to 5V is 10K. It is recommended to use external transistor if intended to source current.
The de-rating curves are valid for input voltages of 115VAC to 264VAC. Below 115VAC to 90VAC the convection rating is 180 Watts maximum.
When used in Cover Kit, de-rate output power to 70 % under all operating conditions.
Class II version available, Add "-II" suffix at the end of the Model Number.

Notes:

1. Ripple is peak to peak with 20 MHz bandwidth and 10 μF (Electrolytic capacitor) in parallel with a 0.1 μF capacitor at rated line voltage and load ranges.

Signals

Power Good Signal	TTL signal goes high after main output reaches 90% of its final set value, delay is 0.1 to 0.5 s.

Remote Sense	Compensates for 200 mV drop.
Remote on/off	To turn-on PSU short remote pin to ground.
