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).

BATTERY CHARGING
The CV/CC regulated power supplies are 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.
