Full Load, 230VAC. Varies with distribution of loads among outputs.
V1 load for full regulation on V2. All models operate
at no load without any damage and meet all specs on V1 above 0 amps.
Full load, 20 MHz bandwidth.
At 15 CFM forced-air cooling. See Application Note for details.
Convection: Consult Factory.
Output voltage overshoot/undershoot at turn-on.
Varies by output. Total regulation includes: line changes from 85-132 VAC
or 170-264 VAC, changes in load starting at 20% load and changing to 100% load.
Maximum deviation due to a 25% load change with unit at 75% load.
Time required for initial output voltage stabilization.
Time required for output voltage to rise from 10% to 90%.

Fully protected against output short circuit or overload. Automatic recovery upon
removal of overload condition.
Total (+sense and -sense) voltage compensation for cable losses.
AC/DC indicator - This signal indicates the status of the AC input or DC outputs.
When there is sufficient AC voltage and the outputs are operating normally, an
open collector signal is provided.
Turn-On delay time from application of AC:
50
Warning time before outputs go out of regulation:
5
Warning time before outputs deviate ±10% from the nominal value:

Sink Current
Pull-up Voltage
Provided on dual-output models. Open collector signal intended to drive an LED.
Closed collector occurs when the Power Good Signal is in its open collector state.
Sink Current
Pull-up Voltage
Protected against overtemperature conditions.
Unit recovers when overtemperature condition is removed.
Up to 4 units can be connected in parallel.
There are some limits for parallel operation. See Applications Note.
N+1 redundancy is provided. V2 needs an external isolation diode for N+1 operation.
Internal isolation diode is provided on V1.
