REP series energy feedback power supply
REP series energy feedback power supply
|
• Working mode can be selected: Constant voltage, constant current, constant power working mode
• Full-bridge phase-shift soft-switching technology, the whole machine efficiency is over 90%.
• High input power factor: full load up to 0.99
• PWM rectification plus DC/DC two-stage circuit can achieve a wide output voltage range.
High precision and fast dynamic response;
• IGBT bidirectional rectification, full-bridge IGBT inverter technology, fast transient response,
Features such as short recovery time. Meet the needs of energy feedback in motor testing.
• It has perfect protection measures and can be unattended when the power supply is running.
• Adopting two-pole transformation, IGBT-type circuit mode, pure digital chemical frequency isolation power supply, leading technology;
• High precision: output voltage accuracy 0.1% FS
