Technologically advanced and supplied in various types of combinations

In most cases the supply is either 72 Vdc or 110 Vdc from the locomotive batteries. The output of the inverters are galvanically isolated from the battery supply.There are a number of combinations that can be supplied for air conditioners:

One 3-phase inverter 230 Vac or 400 Vac or 480 Vac 50 or 60 Hz. The inverter uses “Cycle by Cycle Current Limiting at the switching frequency” and avoids the starting inrush current

Two 3-phase inverters. One for the compressor and another for the blowers

One 3-phase inverter 230 Vac or 400 Vac or 480 Vac 50 or 60 Hz for the compressor plus one 1-phase inverter 230 Vac for the blowers and the control of the air conditioner system
