STANDARD CONTROL SIGNALS
Remote enable
See Figure 1
DC OK
(See Figures 2 and 5)
Signal remains "Hi" as long as
output is ±5.0% of nominal.
AC power fail signal
(See Figure 5)
Signal "Hi" when AC >85VAC and
"Lo" when <75VAC.
Margin Hi/Lo (V1)
(See Figure 3)
Allows ±5.0% change in output
for system margin checking.
Remote Adjust
(See Figure 4)
The outputs may be remotely
adjusted linearly ±10% .
Current Monitor
Analog signal indicates load current in
single or parallel operation. 5±0.5VDC
represents FL, resistive load 103kΩ.
