The HM7042-3 Triple Power Supply is a compact instrument developed for
10mA
current and voltage supply requirements in the laboratory field. The unit is
manually controlled featuring linear voltage regulation with low ripple and
(static) typ. 7mΩ
noise. This newly designed instrument combines DC/DC converters as pre
regulator followed by a linear voltage regulator. Three independent floating
≤ 2.5mV
voltages deliver a total output power of maximum 156W. Either output can be
≤ 80ms
combined in a series or a parallel connected array to either increase the
≤ 0.05%
current or voltage capability.

The output current and voltage is continuously variable in one range from 0V
to 32V and 50mA to 2A. In addition to the two voltages, the HM7042-3 has
an additional output that is rated at 5A and variable between 2.7V and 5.5V.
The change over from voltage control to current control is performed
automatically, based on the load, and is indicated via LEDs. All outputs can
be switched On/Off simultaneously with the push of the output button. When
a current limit value is reached, power is removed from the output to protect
sensitive circuits.
The HM7042-3 posses every safety feature necessary to ensure problem
free operation. The built in fan is temperature controlled and starts operating
after 40°C is reached inside the instrument. Due to its high quality standard,
the HM7042-3, which is stackable with other HAMEG instruments, will
always be a cost effective alternative which rivals other, more expensive
units.
