Remote Sensing Capability
Voltage Drop Per Lead:
Load Voltage:
Up to 1/2 of rated output voltage.
Subtract voltage drop in load leads from specified output
voltage rating.
Load Regulation:
Degradation due to load lead drop in--output:
∆
mV (regulation) = Vdrop(R
sense
-)
Degradation due to load lead drop in + output:
∆
mV (regulation) = V

_ and R

are resistances of respective sense leads.
Maximum Reverse Voltage Current Sink Capability: *
With ac input power applied and the dc output reverse biased
by an external dc source, the supply will continuously
withstand without damage a current equal to its output
current rating.
* Current must be limited by user's external dc source.
Load Voltage: Subtract voltage drop in load leads from specified output
voltage rating.
Maximum Input Power:
7350 VA,
6000 W,
160 W (with no load)
