The dedicated sine-wave inverter power supply for locomotive air conditioners is designed specifically for powering air conditioners on diesel locomotives. It converts the 110V DC power on the locomotive into the 220V AC power required by the locomotive air conditioner. The power supply uses advanced sine-wave pulse-width modulation (SPWM) technology.
Product Description
The dedicated sine-wave inverter power supply for locomotive air conditioners is designed specifically for powering air conditioners on diesel locomotives. It converts the 110V DC power on the locomotive into the 220V AC power required by the locomotive air conditioner. The power supply uses advanced sine-wave pulse-width modulation (SPWM) technology. The main circuit uses a modular design, the power devices use Infineon IGBT from Germany, and it incorporates proprietary drive protection circuitry, advanced DDS reference sine-wave generation, and mature control technology. This results in a compact circuit structure, high efficiency, vibration resistance, pure sine-wave output, regulated voltage and frequency, and high output power. In addition, this power supply has isolated transformer output, making it safe and reliable for users.
Product Features
It is designed specifically for powering air conditioners on diesel locomotives and complies with railway system and industry AC/DC power supply standards. It has a wide input voltage range, high voltage regulation accuracy, and strong environmental adaptability. DDS waveform generation and instantaneous waveform dual-loop control provide high output accuracy and good waveform quality. Complete self-protection and load protection functions help ensure the safety of equipment and operators. Fully isolated inverter technology provides stable output voltage, low waveform distortion, and clean sine-wave AC voltage. The inverter unit uses microprocessor control and SPWM sine pulse-width modulation technology for a clean waveform. Proprietary dual closed-loop control technology ensures reliable operation, and strong overload capability withstands impact from various loads. Protection functions include input battery undervoltage, output overvoltage and undervoltage, overtemperature, and short circuit protection.
