6. CONTROL MODE SELECTION

There are 4 modes, Normal, Preset, Set and Remote Control mode for the power supply.
Slide the Mode Selecti on Switch (8) to your desire d 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 acti on volume knobs.

Push the knobs to toggle t he coarse and fine tuning, notice the subtle changes in brightness of relat ed LED.
Adjust the knobs to your desired values by trying coarse and fine tuning.
To check the preset current level, jus t turn the Current Knob l ightly 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 (9)
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.

6.3 Set Mode – First enter i nto the Set Mode by pushing Switch (8) 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 (9) to the position P1, P2 or P3 which you wa nt to set
b. Adjust the front panel voltage control knob to set your desired voltage value
c. Adjust the front panel c urrent control knob to s et your desired current limit value
d. Repeat the procedure for remaining recalls P1, P2, P3 if desired.
e. Move Mode Switch (8) from Se t to Preset position to confirm your settings.

Remarks:

All the set values in the presets will be kept even after the power supply has been tuned off.
Always check output voltage of Presets before connect to Load
To check the preset values, move Mode Switch (8) to Preset position
Move the Recall Switch (9) to P1, P2 or P3.
The V and I settings of corresponding RECALL P1, P2, P3 will be show on the panel meters.
It is more ease to setup these preset values by using PC software. After set values in PC software and save. Use

Recall switch to use it.

6.4 Analogue Remote Control Mode
To control the output voltage and current by remote control connector (10)
Please refer to paragraph 8

7. Using the power supply

7.1 This series has 3 models. Make sure you have used the correct one.

They have di fferent output voltage range and current as follo wing:

Model Number

Output Voltage Range

Total Rated Current

HCS-3300

1 ~ 16V

0 ~ 30A

HCS-3302

1 ~ 32V

0 ~ 15A
