2. INTRODUCTION
Input single-phase over input voltage range 220VVAC
The output can be grounded and operated as a positive or negative supply.
Embedded microcontroller control.
Front-panel digital encoders provide high-resolution local adjustment of voltage and current programs. Integrated RS-232, RS-485, USB and optional Ethernet communications provide 12-bit precision for remote control programs and monitors.
Remote analog interface. User selection - table 0-5V or 0-10V simulation program - ming and monitor.
Field can be bundled and operated in parallel. Up to 4 identical power supplies can be run in parallel with user-configurable mains and active current sharing
3,POWER SUPPLY DETAIL
Conduct withstand voltage test for tantalum capacitor and ceramic capacitor. In order to ensure reliability, the capacitor test requires the use of a high-voltage power supply that can apply a higher voltage than the standard power supply, because the test is carried out at a voltage of 1.5 to 2 times the rated voltage to ensure reliability.
In the leakage current measurement test, the amount of current flowing when a certain voltage is applied is measured. In order to measure the leakage current, apply a high voltage using a high voltage power supply and measure the leakage current during application.
