Auxiliary Signals

DC OK:

Goes HIGH when main DC output is above 90%

of nominal voltage and goes LOW when the

output is below 90% of rated main output DC

voltage

Power Good/ Power

Fail:

Signal is high within 500mS after the main output is

within regulation band upon AC turn on. Goes low

with 4 mS min. before the main DC output drops

below 90% of nominal value when AC turns off.

Inhibit:

Logic HIGH or open = ON

Logic LOW or short to ground = OFF

Fan Output:

12V @ 1 A (air cooled ) or 0.5A (convection),

+/-10% regulation for load change of 0.5A to FL on the

main output.

Remote Sense:

Compensates for up to 0.5V voltage drop

for 48V & 56V models, and 0.16V voltage drop

for 12V & 24V models. Maximum deviation of

5% (main output) any 50% step above 5% load.

Current Share¹:

Active single wire, up to 4 supplies in parallel. Paralleled

output voltages must be set to within 0.5% of each

other. Contact Factory for details on the required set-up

for proper operation.

5V Standby Output:

5V @ 2A, +/-5% regulation over all

changes in main output load current.

Current Share

Accuracy¹:

5% when the load current is ≥50% of the total

available load current, 10% when the load current is

between 25% - 49% of the total available load current.

Remote sense lines must be connected to ensure

accuracy.

Notes: 1. Consult Factory for proper set-up for current sharing operation.
