Themed ´Versatility – One for All´, Perel OY and HAMEG Instruments showcased the brand-new power supply series HMP last month at the AEL trade fair in Helsinki, which attracted many international test & measurement experts. The HMP series, setting an ‘all new standard’ in the 200/400W power range, proved to be the crowd-puller at the booth. The 200W power supplies HMP2020 and HMP2030, providing up to 32V and up to 10A on 2 and 3 outputs channels respectively, will start roll-out in Q4 2008. The 400W HMP4030, to follow in Q1 2009, provides on 3 output channels up to 32V at up to 10A as well.

All three units have a set- and read-back resolution of up to 1mV/0,1mA. Even fully loaded, the residual ripple voltage stays below 150µVrms. The outputs, earth-free and electrically insulated, can be synchronised using their current- or voltage-tracking functionality. In case of an over-load of one channel, the ´FuseLink´ feature can synchronously shut down all logically linked outputs. To round out the picture, users can easily set up basic voltage- and current curves using the ´EasyARB´ function. For easy integration into 19” rack mount systems, all outputs and sense inputs are also available on the rear side of the devices.
