---

How to make Ground Connections?

For operating with negative or positive output terminal, grounded or without grounding. Connections (+ or -) are made by using the shorting plate at the terminal.

---

What should be noted when operating the supply without being grounded?

When operating this supply without being grounded, high impedance leakage can exist between the power supply circuitry and the chassis ground.

---

What are the Basic Modes of Operation?

This power supply is designed to operate as a constant voltage source or as a constant current source. Automatic crossover to either mode of operation occurs when load conditions change.

---

How does the Constant Voltage mode work?

The power supply will function as a constant voltage source as long as the load current is less than the current limiting value set by the current limit operation. When the load current is equal to or greater than the current limit set, the power supply will automatically crossover and operate as a constant source.

---

How does the Constant Voltage Automatic Crossover mode work?

The power supply will function as a constant source when the load voltage does not equal to the voltage value set by the output voltage control. When the load voltage equals to the value set by the output voltage control the power supply will automatically cross over and operate as a constant voltage source.

---

How to preset Current Limiting Value?

There are occasions when you will not want your load to draw too much current or want you want to prevent any damage, you can preset the current limiting value as follows: Short circuit the output terminals and adjust the current limit control to your desired value.
