Options and fuse information

Warning Ensure you order the proper DC power supply model for the mains power that will be used for the DC

power supply.

Ensure the correct AC input voltage and fuse settings

WisdomAugust

Use the proper switch settings

To change the input AC voltage selector on the power supply, use the two AC selector switches on the rear of the

power supply as shown.

For example, to select 230 V, slide the red switch to the left.

To select 100 V, slide the switch to the right.

WisdomAugust

Use the correct fuse

You must use a time delay 5-A fuse for 110- and 115-VAC inputs, and a time delay 3.15-A fuse for 220- and

230-VAC inputs:

To configure the correct fuse, follow the three steps shown below:

Pull the fuse holder out of the power supply.

Front Panel Operation

Set voltage and current

Note If you are in a menu, you must exit the menu before setting the voltage.

1. Press [Voltage] knob to enter the voltage setup mode.

2. Turn this knob to the desired voltage value, pushing the knob to move between digits.

3. Press [Current] knob to enter the current setup mode..

4. Turn this knob to the desired current value, pushing the knob to move between digits.

5. If the display currently shows OFF, press [On / Off] key to enable the output. Press this key again to turn the output off.

Constant voltage and constant current

If the output load resistance exceeds the voltage setting divided by the current setting, the power supply will

operate in constant voltage mode. The current will equal the voltage divided by the load resistance.

If the output load resistance is less than the voltage setting divided by the current setting, the power supply

will operate in constant current mode. The voltage will equal the current multiplied by the load resistance.

Configure over-voltage protection (OVP)

1. Press [OVP] key to enable or disable over-voltage protection.

2. Press and hold [OVP] key to enter OVP Set mode.

3. Turn the voltage knob to the desired OVP limit value.

Note If OVP is enabled, the OVP key light in white.

WisdomAugust

1. To begin, correct the condition that caused the OVP event. There are three ways to do this:

a. Turn off  OVP as described above.

b. Set the voltage level to be less than the OVP level. You may be able to do this by adjusting the voltage knob.

c. Set the OVP limit value to be above the voltage level.

2. Press [ON/OFF] key to clear.

WisdomAugust

Configure over current protection (OCP)  

1. Press [OCP] key to enable or disable over current protection.

2. Press and hold [OCP] key to enter OCP Set mode.

3. Turn the current knob to the desired OCP limit value.

Note If OCP is enabled, the OCP key light in green.
