30V 50A lab using high voltage DC power supply
are designed as true programmable DC supplies that are particularly
suitable in precise and accurate continuous DC applications where a
stable and well controlled output voltage and current are
essential. These supplies are fully programmable from 0.1% to 100%
of rated voltage/current, with high accuracy and tight
ripple/regulation performance.

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.
