Logic Control
Power failure |
TTL logic signal goes high 50-150 msec |
|
after 5V output. It goes low at least 4 |
|
msec before loss of regulation |
Remote on/off |
Requires an external contact (N.O or |
|
N.C) to inhibit outputs |
DC-OK |
TTL logic goes high 50-150 msec after 5 |
|
V output. It goes low when there is loss |
|
of regulation. |
Remote sense |
Compensates for 0.5 V lead drop min. |
|
Will operate without remote sense |
|
connected. Reverse connection |
|
protected. |
