SRI70-5K Special inverter power supply for locomotives
A locomotive inverter power supply that can replace imported brands
SRI70 series sine wave inverter power supply for locomotive air conditioner is specially designed for power supply of diesel locomotive air conditioner. It converts 70V DC power on the locomotive into 220V AC power required by locomotive air conditioner. The power supply adopts advanced sine wave pulse width modulation (SPWM) Technology, the main circuit adopts a modular design, the power device adopts German Infineon IGBT, the unique driving protection circuit of Xinchi, advanced DDS-type reference sine wave generation and advanced and mature control make the circuit structure compact, high-efficiency, anti- Vibration, pure sine wave output, output voltage regulation and frequency stability, high power and so on. In addition, the power supply has an isolation transformer output, which is safe and reliable for the human body.
