DC600V under-vehicle power supply unit charger
delivery time：2 weeks
Name: DC600V under-vehicle power supply unit charger
Model: 25T(G)-8kW+3.5kVA
product description:
The 8kWDC600V/DC110V charger is specially developed and counted for buses with DC600V power supply system. The charger converts DC600V into DC110V through high-frequency conversion, provides a floating charging source for passenger car batteries, and supplies power to other DC loads at the same time. The 3.5KVA single-phase inverter inverts DC110V into single-phase AC220V to provide AC power for the load. The control adopts SPWM modulation, the carrier frequency is high, and the output is sine wave. The power supply also adopts a variety of anti-interference technologies, with good electromagnetic compatibility and high reliability.
Product highlights:
1 25T(G)-8KW+3.5KVA type realizes the small size and light weight of the bus electrical system; high efficiency; high reliability; high quality of power supply to the load; easy to use and maintain.
2 The 8KW charger 485 communicates with the monitoring system, uploading information such as charging current, load current, and operating status.
3 8KW charger type protection functions: • Input over and under voltage protection • Output over and under voltage protection • Output overload protection
•Output overcurrent and short circuit protection •Radiator overtemperature thermal protection •IGBT fault protection •Battery undervoltage protection
• Pre-charge protection • Input, pre-charge contactor protection • Current-limited charging protection
4 3.5kVA single-phase inverter protection functions: • Ability to withstand sudden changes in input voltage • Input over and under voltage protection
•Output overload protection •Output overcurrent and short circuit protection •Output overvoltage and undervoltage protection •IGB fault protection
