HDF programmable high-voltage DC power supply is a reliable test device provided by Shenzhen Infypower Co., Ltd. for laboratories with high efficiency, high power density and low harmonic. The programmable DC power supply covers two control modes: local touch screen control and upper computer programming control (RS485 Modbus).
Infypower DC Power Supplies cover a wide range of power, voltage and current with advanced features for lab or rack-mounted applications. They include a wider operating range with constant power, higher current ranges, precision readback of output current and voltage, output trigger signals, as well as the ability to create complex DC transients waveforms to test device behavior with voltage deviations.
