The JFWY-D series high-power programmable DC regulated and stabilized current power supply is an integrated power product that combines control capabilities. The power supply system adopts soft-switching inverter technology, developed with new IGBT power devices and amorphous magnetic cores as core components. It offers high precision in output voltage and output current, and can detect and display its own operating mode, making it user-friendly.

Utilizing ZVZCS soft-switching technology, switching losses are reduced by 70%, with overall efficiency exceeding 95% (traditional hard-switching power supplies only achieve 80% efficiency). Meanwhile, noise is kept below 55dB (measured at 1 meter), making it suitable for quiet laboratory environments.

It supports RS485/MODBUS protocol, allowing parameter setting, status monitoring, and multi-unit synchronization via host computer software, compatible with industrial automation production line integration.

Equipped with built-in short-circuit, overcurrent, overvoltage, and overtemperature protection circuits, core components use imported IGBTs and control chips, with MTBF (Mean Time Between Failures) ≥ 50,000 hours.

The JFD series programmable DC regulated and stabilized current power supply comes with remote control interfaces and is available in cabinet-type and standard rack-type configurations. The company also possesses strong R&D capabilities, enabling customized development based on customer needs, and can provide host computer monitoring software for user convenience.
