Thermal protection
Yes.
Programming
Analogue Programming of voltage and current by
0-5V.
Programming speed
See table.
Master/Slave operation
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.
Metering
Digital meters standard.
Indicators
CV/CC mode, OVP triggered LEDs.
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.
ENVIRONMENTAL
Operating temperature
-20°C to 50°C.
Cooling
Low noise blower, fan speed adapts to
temperature of internal heatsink. (from left to
right).
