– HMP does have many features included which are not available in power
supplies of this price range like:
• high resolution DMM in each channel for very high setting and read
back resolution for voltage and current.
• Overvoltage protection for each channel
• Fuse link to define case depended and save switch off of different
channel
– EasyArb function import from a PC or program inside the HMP a
arbitrary waveform where at each definition point voltage and current
can be set
– Remote interface RS-232/USB is standard delivered with each HMP, the
remote control functions are based on SCPI Commands for easy top
level programming
– High contrast LCD Display to show all important values at once
– Low fan noise due to big fan and temperature controlled fan

Current protection
– If the output current reached the current protection limit, the
power supply change to the constant current mode. The output
voltage will be regulated down, in the case of a short to 0
voltage.
– The limit current which was set will flow as long as the overload
on the output is over. Then the power supply will be
automatically switch back to constant voltage mode.
