2-in-1 Drive (DC-DC & Inverter)

The 2-in-1 driver (NB100-D-075-020) is mainly used in new energy commercial vehicles, which can be used as a DC power supply as well as providing 0-380V AC power. This driver is a high-performance switching power, which can be specially designed to supply power for 24V fans, water pumps, etc. as well as the compressor of vehicle air conditioners. It can be widely used in pure electric vehicles and hybrid vehicles. The driver is characterized by high reliability, high efficiency, small size and light weight.

Technical Specification

Inverter
Basic Functions	Maximum Output Frequency	Vector control: 0-400HZ
	Carrier frequency	0.8khz–12khz (automatically adjusted according to load characteristics)
	Control method	SVC open-loop vector control (synchronous machine)
	(AVR)Automatic Voltage Regulation (AVR)	Can automatically keep the output constant when the grid voltage changes
