SAFETY BRIEF

This manual contains important safety instructions that must be followed in the operation and storage environment of the SPS series. To ensure your personal safety, and ensures that this product works in the best environment, please read this manualcarefully before using .

When you get a brand-new power supply, you need to do the necessary checks to make sure the instrument is working properly.

1. To check whether there are damages caused during transportation.

2. To check whether all the accessories are complete.

3. To check whether the output voltage and output current are normal after turning on the device.

If finding out any problems, please contact the merchant immediately.

SAFETY SYMBOL

The safety symbols below will appear in this manual or on the DC power supply.

PRODUCT BRIEF

The SPS series of adjustable regulated DC power supply designed for use in laboratories, schools and production lines.

Both output voltage and output current are continuously adjustable between 0 and nominal.

The stability and ripple factor of the power supply are very good and have a perfect protection circuit. Can work at full load for along time. This power supply can be used as both a regulated power supply and a regulated current supply.

WORK REQUIEMENT

1. AC input: Please make sure the input voltage of this product

230V±10% 50Hz

115 V±10% 60Hz

2. Do not use in an environment where the ambient temperatureexceeds 40 degrees Celsius. The cooling fan is located at the rear of the device and should have enough space for cooling.

Warning:Incorrect AC voltage input will cause serious damage to the device.Please make sure the required input voltage value.

OPERATION INSTRUCTION

There are two types of power output modes: constant voltage output (CV) and constant current output (CC). The output modeis determined by the voltage and current values set by the user and the load connected by the user. The output voltage or current value of the power supply won't exceed the voltage and current values set by the user. In constant voltage mode, the output voltage value is equal to the user-set voltage value. In constant current mode, the output current value is equal to the user-set current value.

For example: the voltage value is set to 5V and the current value is set to 5A.

Steps

1. Turn on the powe switch

2. Adjust the voltage adjustment knob to 5V

3. Connect the“positive”and“negative”with wires and adjust the current knob to 5A.

4. Disconnect the wire and connect the load to use.

CONNECTTHE LOAD

1. Rotate the terminal knob by turning it counterclockwise

2. Insert the load terminal

3. Turn the terminal knob clockwise

4. Banana plug can be directly inserted into the terminal hole

CONSTANT VOLTAGE /CONSTANT CURRENT CHARACTERISTICS

The working characteristics of this series of power supplies are constant voltage/constant current automatic conversion type,which can automatically change between constant voltage and constant current states with load changes. The intersection between constant voltage and constant current mode is called conversion point.For example, if the load causes the power supply to operate in a constant voltage mode, a constant voltage is output. As the load increases, the output voltage will remain constant and the output current will increase. When the current value reaches the set current limit value, the power supply will automatically switch to constant current mode. The output current remains stable and the output voltage decreases proportionally as the load increases further. The conversion of constant voltage and constant current is indicated by the LED on the front panel.

CV indicator light is on during constant voltage, CC indicator is on when constant current.

FUSE REPLACEMENT If the fuse blows,the power supply will stop working.To find and correct the cause of the blown fuse,then replace it with a fuse of the same specification.
