Parallel and series operation with equal current
and voltage sharing. In this way two or more SM-
units can together be used as one high power
unit. Voltage and current of the units is controlled
by the master (by potentiometers or by
programming). Series operation up to 600V

BATTERY CHARGING
The CV/CC regulated power supplies are very suitable for battery charging.
Ask for the special datasheet “BATTERY CHARGING WITH SM-series POWER
SUPPLIES”. This datasheet contains information about protective measures
against accidental battery reversing.
