WHFW-GJD Series High-Precision Enabling Power Supply

WHFW-GJD Series High-Precision Enabling Power Supply

The high-precision enabling power supply adopts IGBT inverter soft switch linear rectifier, DSP microcomputer digital control and instantaneous value of double closed loop control system. With fast output response speed, it is non-overshoot. This power source owns extraordinary small ripple coefficient and high stable precision. Output current and voltage is continuous and adjustable. The high-precision enabling power supply is mainly used as factory aging enabling test power supply of military service tantalum capacitor. This power source can also be used in aviation, aerospace, ship and national key lab and other areas where DC power supply with high precision, high stability, high reliability and low ripple is needed.

Main Technical Features of High-precision Enabling Power Supply:
1. This power source's master controller adopts DSP computer digital instantaneous value of double closed loop control. It is of fast response speed and non overshoot.
2. The high-precision enabling power supply owns many protection functions including open phase, over voltage, under voltage, quick fuse or fuse alarm protections of AC power supply, output over current and current limiting protections. This power source also possesses functions of output short circuit and instantaneous overload protections, over temperature and overheat protections of IGBT power switch components, switch rectification transformer and bus copper bar. 
3. The high-precision enabling power supply can store and record process historical curves of current, voltage and frequency.

4. For communication interface means, we can configure CAN BUS, PROFIBUS, ETHERNET, RS485 and RS232 optical fiber communication interface to realize remote control or monitoring according to customers' requirements.
5. This power source can be connected with computer through RS485 communication interface, and can also be stored by U disk then re-stored to computer. It is convenient to save customers' files.
