At a glance
One, two or three channels – R&S®HMC804x power supplies with their
specifications and wide range of functions are ideal for use in development
labs and industrial environments. Thanks to their high energy efficiency, the
linear power supplies remain cool and quiet, even at maximum load. Practical
interfaces and connectors allow users to work quickly and conveniently with
the R&S®HMC804x, even in 19“ racks.
The R&S®HMC804x family consists of three models with a maximum total power
of up to 100 W and a continuous voltage range from 0 V to 32 V. The one-channel
R&S®HMC8041 delivers a maximum of 10 A, the two-channel R&S®HMC8042 a
maximum of 5 A and the three-channel R&S®HMC8043 a maximum of 3 A per
channel. The two-channel and three-channel models enable users to connect
multiple outputs in parallel or in series to increase the voltage or current. The
outputs are galvanically isolated, floating, and protected against overloading and
short circuits. Voltage, current and power values are output on a brilliant QVGA
The R&S®HMC804x offers a wide range of logging functions, an integrated
energy meter and electronic fuses that can be individually combined for
each channel, making it ideal for hardware developers, labs and industrial
environments. Linear switching power supplies ensure high efficiency, for
minimum heat dissipation even at full load. Developers and industrial users
benefit from useful functions such as sequenced start of channels, EasyArb
and EasyRamp functions that are directly programmable on the device, an
analog input for external control of voltage values, an external trigger input
for controlling channels and arb steps, and adjustable overvoltage/overpower
protection for each channel.
All connectors, including SENSE, are available on the rear panel. A cage clamp
facilitates rack installation and deinstallation. The LXI-compliant power supply
can be controlled via LAN, USB or an optional GPIB interface. The CDC (virtual
COM port) and TMC classes are supported for communications via USB. The
remote control commands are based on the SCPI standard.
The R&S®HMC804x power supplies from the Rohde & Schwarz value instruments
product range offer top quality and intelligent, practical functions at an extremely
attractive price.

Ideal for industrial environments
Power supply units in industrial production environments are often found in
19” racks. The HMC804x series instruments are very suitable for this use as all
models can be integrated into 19” racks with the rack mounting kits HZC95.
Two HMC8043 models built side by side result in 6 channels on 2 rack units.
Please ensure sufficient space is available in the rack for adequate cooling
(required minimum space above a HMC804x: 1 rack unit).
Additionally, all front panel connectors plus SENSE lines are located at the
back panel of the instrument. In order to facilitate the regular fitting-out for
calibration the rear panel connector was designed with a WAGO cage clamp.
The complementary part is available as option HZC40.
