Additional Details
The STTL3000KA AC/DC charging module is designed for low-voltage charging equipment. It uses DSP digital control, resonant soft switching and active PFC for high power density, high power factor, low harmonics and high efficiency. It supports parallel installation for higher power and provides a 16–120 Vdc wide output to meet current and future low-voltage charging requirements.
Applications: e-scooters, e-mopeds, e-bikes, e-tricycles, e-forklifts, golf carts and other low-speed EVs.
