Mode Descriptions
Control Mode Selection
There are four modes: Normal, Preset, Set and Remote Control mode for the power
supply. Slide the Mode Selection Switch to the desired Mode. The power supply
defaults to the Normal Mode with maximum current level CC.
Normal Mode
Normal Mode is the factory preset mode. The power supply’s output voltage and current
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 the desired values by trying coarse and fine tuning. Turn the Current Knob lightly in
any direction to check the preset current level. The display will resume its normal
brightness after a few seconds to confirm the adjustment.
Preset Mode
In this mode, the Rear Control Light is on to indicate panel voltage and the current
controls are de-activated.
There are three preset outputs, P1, P2 and P3. These are selectable by using the
Recall Switch located on the rear of the power supply.
The preset values are factory set as shown in the following table. The output rating is
adjustable.
Presets. Output Voltage Output Current
P1 5V Maximum
P2 13.8V Maximum
P3 25V Maximum
Set Mode
In this mode the voltage and current remote control can be used at the same time or
separately.
1. Set the Mode Switch located on the rear of the power supply to the “Set” position.
2. To define the preset output set the Recall Switch to the P1, P2 or P3 position.
3. Use the front panel Voltage Control Knob to set the desired voltage value.
4. Use the front panel Current Control Knob to set the desired current value.
5. Repeat the procedure for the remaining presets: P1, P2 or P3 if desired.
6. Move the Recall Switch from the Set to the Preset position to confirm settings.
