Description

The series of switching power supplies for measuring instruments have figured out the inconvenience of the big volume and heavyweight of a traditional power supply possess. The output voltage and current are controlled by two spiral buttons regulation for more handy and precise adjustment. This power supply is suitable for research institutes, laboratories, and factories, where the DC stable power supply is needed.

 

Key Features

HD Display: This DC power supply is equipped with a high-definition display, which can clearly and intuitively show the resolution of the voltage, current, and power of the power supply, making it easy for users to visually observe the data.

 

Extensive Range of Input Voltage: This DC power supply has an input voltage of 115V±5V. The wide voltage allows it to be used for wider purposes, so it is convenient for the users.

 

Stable Operation: This DC power supply can output a stable and continuous voltage and current. You only need to control the rotary button to ensure that the output is constant current and voltage.

 

High Efficiency: The entire efficiency rate of this power supply is higher up to 70%, which allows this power supply to output stable current quickly.

 

Fast Heat Dissipation: The shell of this DC power supply is equipped with heat sinkholes to help dissipate heat inside the power supply. So even if it works for a long time, you don't have to worry about it will be burned out.

 

Easy to Operate: This power supply can be used by turning on the switch after accessing the electricity. The voltage and current can be adjusted by rotating the spiral button, so it is very simple and easy to operate.

 

Easy to Move: This power supply is very small and lightweight. It measures 23*7*13cm/9*2.8*5.1inch and weighs 1.3kg/.2.87lbs, so an adult can easily move it.

 

Guaranteed Customer Service: We aim to provide quality products and services. If you have any problems, please feel free to contact us. We will reply and solve the problem for you as soon as possible.

 

Details

Constant-current and Constant-voltage Indicators: There are two indicators on the electronic screen of this power supply, they are the constant-current ( c.c) indicator and the constant-voltage ( c.v) indicator. These two lights allow users to easily and quickly understand the constant current and constant voltage of the power supply.

 

Precise Spiral Buttons: The output voltage and current is controlled by two variable spiral buttons. These two resistors can adjust the voltage and current precisely. So you can adjust the right voltage and current according to your needs.

 

Application

This power supply is suitable for research institutes, laboratories, and factories, where the DC stable power supply is needed.

 

Package Included

1 * DC Power Supply

1 * Power Cord
