Operating Instructions
REOTRON SMP

ELEKTRONIK
1.0
General
Primary switching circuit with DC output. Internal regulator for voltage, current or power control.
Controlled from two setpoints (setpoint 1 = voltage, setpoint 2 = current) using either a 0...10 V, 0(4)...20
mA analogue signal or a Potentiometer. Setpoint 1 is used in the power regulation mode. The touch panel
is used for making settings and keys “I“ and “O“ can be used for switching the output ON and OFF
.
However, this does not provide isolation of the mains input.
The units can be used in parallel or
series connection for providing higher power outputs.
