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.
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-3304 is over 60VDC, avoid touch the metal contact part of the output
terminals.
•
Analogue Remote Control 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.
•
The gauge size of input power cable must be at least 0.75mm
3m.

6. CONTROL MODE SELECTION There are 4 modes, Normal, Preset, Set and Remote Control mode for the power supply. Slide the Mode Selection Switch (8) to your desired Mode. The power supply is factory preset to Normal Mode with maximum current level CC. 6.1 Normal Mode This is the factory preset mode and the power supply output V, I are controlled by the dual action volume knobs. - Page 4 7. Using the power supply 7.1 This series has 3 models. Make sure you have used the correct one. They have different output voltage range and current as following: Model Number Output Voltage Range Total Rated Current HCS-3300 1 ~ 16V 0 ~ 30A HCS-3302 1 ~ 32V...
- Page 5 7.4 Using the control knobs The rotary encoder control knobs have fine and coarse tuning with clicking movement. Push the knobs to toggle between coarse and fine tuning, notice the subtle changes in brightness of related LED. Adjust the knobs to your desired values by trying coarse and fine tuning. The display will resume its normal brightness after few seconds to confirm your adjustment.

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. - Page 8 8.2 Method B Using two 0 – 5K Ohm variable resistors Two variable resistors must be set up at the same time in order for the remote control to be functional.
