HCS-3600/3602/3604

Laboratory Grade & High RFI Immunity Switching Mode Power Supply with Rotary Encoder Control

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 ¤t be adjusted without touching the front
panel of the power supply.
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.

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-3604 is over 60VDC, avoid touch the metal contact part of the output
terminals.

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.

6. CONTROL MODE SELECTION

There are 4 modes, Normal, Preset, Set and Remote Control mode for the power supply.

Slide the Mode Selection Switch (9) 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.

Push the knobs to toggle the 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 .

To check the preset current level , just turn the Current Knob lightly in any direction .

The display will resume its normal brightness after few seconds to double confirm your adjustment.

6.2 Preset Mode

a. In this mode , the Rear Control Light is on to indicate panel V & I controls are de-activated.
b. There are 3 preset output P1/ P2/ P3 at the Recall Selection Switch (10)
c. The preset values are factory set as following table.
d. End user can set his own output rating, please refer to paragraph 6.3

Recall No. Output Voltage Output Current

P1 5V Maximum

P2 13.8V Maximum

P3 HCS-3600: 15V

HCS-3602: 25V

HCS-3604: 55V

Maximum

6.3 Set Mode – First enter into the Set Mode by pushing Switch (9) to Set Mode slot.

The power supply is then ready to be preset.

6.3.1 To define the preset output P1/ P2/ P3.

a. Select the Recall Switch (10) to the position P1, P2 or P3 which you want to set
b. Adjust the front panel voltage control knob to set your desired voltage value
c. Adjust the front panel current control knob to set your desired current limit value
d. Repeat the procedure for remaining recalls P1, P2, P3 if desired.
e. Move Mode Switch (9) from Set to Preset position to confirm your settings.

Remarks:
