0 – 32 V / 2 A
Output voltage, adjustable 0 – 32 V. Safety terminals for 4 mm
plugs. The outputs are short circuit-proof with no time limit.
Œ ”
VOLT
7 segment , 4 digit LED display of the actual values of all voltages,
the resolution is 10 mV. The display are always operative, even
when the outputs are disabled allowing presetting of all output
voltages before the loads are connected to them. We recommend
to always follow the procedure of setting the output voltages first
and then turn the outputs on.

These LEDs will light up if current limiting was activated and I
was reached.
Ž
AMP.
4 digit 7segment displays of the actual output currents, resolution
1 mA. We recommend to set the I
voltages on.
COARSE/FINE
Rotary controls for the coarse/fine adjustment of the 0 – 32 V
outputs.
0 – 32 V / 2 A
Outputs, 4 mm safety connectors
CURRENT LIMIT
Rotary controls for setting the maximum currents of the 0 – 32 V
outputs. If a control is turned fully CCW to 0 A all outputs will be
turned off immediately if the function "electronic fuse" was
activated. In case "Current limit" was selected the LEDs
will light up, the voltage will drop to zero.

This output voltage can be adjusted 0 – 5.5 V. 4 mm safety
connectors. This output is short-circuit proof without a time limit.

VOLT
3 digit 7segment display of the actual output voltage, resolution
10 mV. This display will show the output voltage even if the output
was switched off. Hence the voltage may be set before the output
is activated. This is what we recommend.

Rotary control for setting the maximum output current 0 – 5 A. If
the control is turned all the way CCW to 0 A all outpts will be
turned off immediately if the mode "electronic fuse" was selected.
