See table
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
Digital meters standard
Indicators
CV/CC mode, OVP triggered LEDs
MTBF
500,000hrs
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.
