YN5050 three-phase program-controlled precision test power supply adopts a meter-source integrated structure, using embedded systems, large-screen TFT color liquid crystal displays and touch screens, CPLD chips and high-precision A/D, D/A and a series of devices, small in size and light in weight.

1. The touch screen control panel and mask buttons are used to display a large amount of information, which is simple and convenient to use.

2. Built-in electric energy meter, displaying voltage, current, frequency, phase, active power, reactive power, apparent power, power factor and other parameters.

3. With multiple protection functions: current limiting protection, power amplifier protection, voltage short circuit protection, current open circuit protection, power amplifier thermal protection and other functions.

4. Intelligent gear position: within the allowable output range of the instrument, the user can arbitrarily set the respective rated voltage and current gear positions of the three-phase voltage and current. The test points and adjustment fineness of voltage and current refer to the rated gear position set by the user Value, convenient for user operation.

5. Abundant test points for voltage, current and phase are easy to operate.

6. With RS232 serial port, it is convenient for computer control and software upgrade.
