Laboratory Grade & High RFI Immunity Switching Mode Power Supply with Rotary Encoder Control
1. INTRODUCTION
Since the introduction of HCS series power supplies in 2009, we have made numerous improvement within the limits of
the original hardware modules, firmware and software framework.
In the upgraded version of HCS series power supplies, both the hardware and the firmware have been modified, the
application software has a completely design in concert with the value added features.
Added features which can be done on the unit panel.
1. Reset no load current to zero on current meter.
2. Reset the 3 presets to factory default

Page 7: Analogue Remote Control Mode
8. ANALOGUE REMOTE CONTROL MODE There are two methods for remote control of current and voltage adjustment. Both methods require both the current remote control part and the voltage remote control part to be set up and be in used at the same time in order for analogue remote control mode to be functional. Otherwise unit will be in CC mode all the time and the analogue remote control will not be functional. -
