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
2. WARNING
•
Do not use this power supply near water.
•
Do not operate or touch this power supply with wet hands.
•
Do not open the casing of the power supply when it is connected to ac mains.
•
Refer all servicing to qualified service personnel only.
•
Before replacing the AC fuse at AC socket , find out and clear up the cause first.
•
Replace the AC fuse with the same type and rating as the original fuse.
•
The max. output voltage of Model HCS-3404 is over 60VDC, avoid touch the metal contact part of the output
terminals.
•
Analogue Remote Control or Remote Programming via USB function is only suitable for stand-alone one unit
operation.
•
Do not use this power supply with electrical motors, solenoid or inductive load that generates a back EMF and
voltage transient which may damage the power supply
3. CAUTION
•
Use a grounded 3 pin AC source.
•
This unit is for indoor use only.
•
Do not operate or place this unit in a humid, dusty, in direct sunlight location or near any heat source.
•
Before plugging into local AC mains, check with the rating label at the back of the unit.
•
Do not block any ventilation openings of the unit.
•
This unit must be used within the specified rating, regular excessive continuous loading may cause damage to the
power supply.
•

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. -
