EXTERNAL ANALOG CONTROL FUNCTION
The rear panel of the PSU-series has an analog control terminal. The external
analog control interface allows external voltage or resistance to control voltage
and current output; and allows power supply to output or to be turned on and
off. The diagram on the shows typical connection methods for externalupper
control applications. For more detailed connection information please refers
to user manual.

PSU-Series Built-in Bleed Resistor
BLEEDER CONTROL
VARIOUS INTERFACES SUPPORT
The PSU-Series employs a bleed resistor in parallel with the
output terminal. Bleed resistor is designed to dispatch the power
from the power supply filter capacitors when power is turned
off or the load is disconnected. Without a bleed resistor,
power terminal may remain charged on the filter capacitors
for some time and be potentially hazardous. In addition,
bleed resistor also allows for smoother voltage regulation of
the power supply as the bleed resistor acts as a minimum
voltage load. The bleed resistance can be turned on or off
using the configuration setting.
