The outputs are isolated from the chassis GND. However, an internal I0M
bleeder
resistor is connected from output return (-) to chassis ground. This allows operation
with floating outputs, or with either the negative or positive terminal of the output
referenced to chassis ground.
Master/slave paralleling is possible to allow multiple units to be operated in parallel for
greater output current or power. The master unit has full control of the other slave units
in setting the output voltage, current, and OVP. Multiple units can be connected in
series for increased output voltage, within the 300V float limitation of the output
terminals.
Remote programming is available with the standard non–isolated analog interface.
Output voltage, current, and OVP are fully controlled with user selectable programming
voltage levels or resistance programming.
Analog output signals are also provided to monitor the output voltage and current. In
addition, a complement of digital input/output signals allows control and monitoring of
the operational state of the supply. Optional interfaces such as GPIB, RS-232, isolated
remote analog, and LXI
TM
Class C Ethernet Interface allow adaptation of the supplies to
a variety of applications.
