Remote Programmable Laboratory Grade Switching Mode Power Supply
User Manual
1. INTRODUCTION
This family of efficient, upgraded SMPS with small form factor, auto cross over CV CC, 3 VI presets, remote control
offers unique solution for various loading conditions and applications.
The dual action (coarse/fine tune) rotary encoder tuning with MCU makes setting the voltage and current levels ever so
smooth, precise and fast. Setting, changing, and checking the current limit level can be done easily without sparking the
output poles.
The remote control functionality allows the output power on/off, voltage &current be adjusted without touching the
front panel of the power supply.
The USB port is added for access to computer to run cyclical operation with Max. 20 programmable sets of preset of
voltage and current with different time duration and up to 999 cycles.
It is suitable for a wide range of applications such as laboratory, telecommunication, production testing, field test of
voltage critical distant load, powering of dc network and etc...
The 3 user defined presets facilitate quick access to frequently used VI settings.

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-3400
1 ~ 16V
0 ~ 40A
HCS-3402
1 ~ 32V
0 ~ 20A
HCS-3404
1 ~ 60V
0 ~ 10A
7.2 Check the rating label of the power supply and make sure it complies with your AC mains voltage.
Connect the power supply to the AC Mains using the provided power cord.
Make sure the Mode Switch (8) is at Normal Position.
7.3 The power supply will perform a series of self checks when it is switched on.
The LED and other indicators on the front panel will be on by turn. When the cooling fan is being checked, a high
speed wind noise can be heard.
After the self checks, the CV, V and A LED indicators are lit up displaying voltage and 0.0 current. To find out
about the set CC current level, just turn the current control knob one click in either direction. The current display
returns to 0.0 after a few seconds.

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.
7.5 Connect the equipment to the power supply. Red (+) is connected to the positive polarity input of the equipment
and Black (-) is connected to the negative polarity input of the equipment.
7.6 Switch on the power supply first and the panel meter & green CV Indicator should light up again.
7.7 Switch on the equipment and the panel meter & green CV Indicator should still remain in green.
7.8 You can now operate the equipment.
When an operation is finished, switch off the equipment first and then switch off the power supply.
8. REMOTE CONTROL MODE
There are two methods for remote control of current and voltage adjustment.
Both methods require current remote control part to be set up in order for remote control mode to be functional,
otherwise unit will be in CC mode all the time.

the panel meter.
D. You also can adjust the output by voltage & current control knob to your desired value when output is off.
Remark: using the 8pin remote plug provided and connect with 22AWG wires.
Pin numbers are marked
on the black portion.

9. FAULTS AND TROUBLE SHOOTING
9.1 OUP: Over Voltage Protection
This unit has a built-in tracking over voltage protection feature. In the event of output voltage becoming
greater than the set value (see specified range from specifications table), protection will be triggered and the
output power will be cut off and OUP warning appears as below.
To reset the warning, switch off the unit and remove all loading.
Switch the unit back on again and it should resume normal operation.
If this problem persists, please contact and consult with your agent.
9.2 OTP: Over Temperature Protection
There is a thermo sensor inside the unit to monitor and to prevent the unit to gets too hot inside. At OTP, there
is no output and the following warning will appear on the LED display.
When you get this warning, switch off the unit and remove all loading.
Check your load and output setting. Allow the unit to cool down for at least 30 minutes.
Check if any of the ventilation is blocked, check enough clearance around power supply.
Listen carefully for the short wind noise from the cooling fan when you turn on the unit again.
If you cannot hear this routine self test wind noise on switch on, the fan is fault and do not use the power
supply, contact your agent.
9.3 OLP: Over Load Protection
Normally the overload protection is sustained by the CC constant current mode.
When the CC mode fails and goes undetected, it may cause serious damage to your test piece or load.
The OLP is to minimize the extent of damage to your loads as power supplies do fail someday.
Switch off your power supply as soon as you see this warning as shown below.
To reset this warning, switch off the unit and remove all loading.
Switch the unit back on again and double check with caution.
If this problem cannot be fixed, please contact and consult with your agent.

12. Appendix
HCS USB configuration for remote programming
This application note describes the procedure to configure the USB port for HCS remote programming application.
HCS remote programmable power supply with USB can connected to PC through USB cable.
USB to serial bridge design is used. When connected to PC, it will be converted as COM port shown in the following
picture. e.g. COM3
If the COM port does not come up, please check if the USB driver has been probably installed.
The USB driver comes with HCS software CD. Make sure the CD has been load to computer first.
Then it can program as stand COM port.
The default COM port setting;
baud rate : 9600
Data bits : 8 bit
stop bit : 1
Parity : None
The HCS then can be programmed for remote control etc. by the ASCII commands via the COM3.
All the command sets are given in the user manual of the power supply.
