Current limit

Increase of output voltage and output current

Security note

The HM7042-3 may exceed the safe low-voltage of 42V in
seriel operation. This might lead to danger when touching
voltage-carrying areas. It is therefore strongly recommended
that the HM7042-3 is operated only by qualified personnel
acquainted with the dangers involved.
32
or constant current modes is automatic. Constant current mode is
indicated by a illuminated LED (5)/(13)/(18) in the respective
display. As long as this LED´s are on, the power supply is operating
in constant current mode (CC = constant current).
The HM7042-3 has 3 individual current limits, one for each output
voltage. For the each 0V - 32V sources the current limit can be
adjusted continuously between 0A and 2A with the Potentiome-
ters (6)/(17).
The current limit for the 2,7V - 5,5V source with Potentiometer
(14). Continuosly 0 -5A
The HM7042-3 features 3 supply voltages wich are galvanically
separated. This enables the user to use the seriel and parallel
connection of the sources as well as simple operation of three
independent sources.
The maximum output current of the HM7042-3 is limited to 2A. if
it is used in serial operation.
Up to can be obtained by parallel connection.
Not counting the 5.5V source (11), the following combinations of
current and voltage are possible:
2 x 0-32V / 2A
1 x 0-64V / 1A Attention! Dangerous voltage level!
1 x 0-32V / 4A
If also using the 5V source, the combinations include also
1 x 2,7-5,5V / 7,3A and 1 x 69,5V / 2A.
