Power Supplies

Keeping things simple – One for All

The power supplies market is highly partitioned. The user is faced with a seemingly unlimited number of models with diverse specifications, the result being the accumulation of a whole assembly of power supplies in the design lab or test site, the better part of which are rarely used.

HAMEG Instruments’ two types of power supplies (HM8143 and HMP4040) cover numerous applications; each type excels by being universally applicable, simple to operate, its compactness, and an unexcelled price/performance ratio. Test sites especially value this advantage because universal instruments minimize set-up times. The power supply portfolio consists in total of 6 types in order to also care for smaller budgets.

In the HMP series there are two 200 W and two 400 W types available which cover the range of 0...32 V and up to 10 A, depending on the number of channels required. This series is based on a classical concept with a mains transformer, high efficiency electronic pre regulators and linear post regulators. This concept yields the high power in the smallest space with the highest efficiency. The HMP series further excels by its intelligent power management which allows higher currents (e.g. up to 10 A) at medium voltages (e.g. up to 16 V) to be made available. Excellent low residual ripple voltages (150 µV_rms) are realized even at full power output. The high adjustment and back-reading resolution of up to 1 mV/0.1 mA fulfills even the strictest requirements. Last but not least there is the EasyArb function available on all channels which allows you to program simple arbitrary voltage and current waveforms.

The HM8143 resides in the 130 W class and is unique in its class with its two 0...32 V/2 A two-quadrant outputs which can operate as source and sink outputs. It also features an arbitrary function, and its output voltage may be modulated via an external input. In the past 20 years, literally thousands of users, predominately in test sites, used this type and its predecessor, the HM8142, taking advantage of its flexibility to realize numerous applications.

The HM7042-5 with 2 x 0...32 V/2 A and 0...5.5 V/5 A is our best selling power supply for many years and became indispensable in many labs.

All power supplies feature galvanically isolated floating overload and short-circuit proof outputs and may be connected in series or in parallel, thus making very high currents and voltages available. A precondition is the common electronic fuse which disconnects all channels simultaneously in case of a fault. The HMP series also provides an extended FuseLink system which allows individual logic combinations.
