Triple Power Supply HM 7042-4
2 x 0 – 32 V / 2 A + 0...5,5 V / 5 A
3 independent floating outputs
Pushbutton for activating/deactivating outputs
Separate voltage and current displays for each output
Adjustable current limit and electronic fuse for each output
Low ripple, high output power, good regulation
Temperature-controlled fan
Parallel and series operation
In this instrument concept the advantages of SMPS (high efficiency)
and linear regulators (good regulation, low ripple) are combined
avoiding the high losses typical of purely linear power supplies.
The current limit of each output is continuously adjustable.
Reaching the current limit will cause automatic switchover from
voltage to current regulation which is indicated by a LED. In order
to protect sensitive loads or such loads which require multiple
voltages an electronic fuse is provided which if activated switches
all outputs off if the current limit of one output is touched.
Practical application is enhanced by a power relay which switches
all outputs ON/OFF if the associated pushbutton is depressed,
hence it is not necessary to turn the whole instrument on/off and
wait for the voltages to build up resp. decrease to zero The fan is
temperature-controlled and remains inactive below 50 degrees C.
The low ripple, good regulation as well as its various saftety
features recommend this instrument for daily practical use.
The
HM 7042-4
known and proven for many years will continue
to serve our customers in the future.
