The JFWY-D series power supply, centered on soft-switching inverter technology, utilizes Siemens Infineon IGBT modules and amorphous core components to achieve "high precision, low ripple, and high efficiency" characteristics. The unit efficiency exceeds 95%, with output voltage/current accuracy reaching ±0.1%, and dynamic response time ≤100μs, meeting the stringent requirements of scenarios such as scientific research testing, industrial production lines, and avionics.

It supports automatic switching between constant voltage (CV) and constant current (CC) modes, with real-time status display via LED indicators, adapting to various load demands (battery charging, chip testing). Employing peak control current and multi-stage filtering circuits, the output ripple ≤10mV, and voltage/current adjustment resolution reaches 0.1% of the rated value, fulfilling the requirements for precision device testing.

Comprehensive protection functions are included. The power supply is equipped with an overload protection circuit internally to ensure the normal operation of the power equipment and the safety of the load; output display. Voltage and current are displayed via high-precision LED digital meters or LCD touch displays; digital control. Fully digital control allows both voltage and current to be programmed digitally; all calibrations are digital, ensuring stability and reliability.
