Infineon Technologies DEMO_850W_12VDC_230VAC Low-Frequency Transformer

Infineon Technologies DEMO_850W_12VDC_230VAC Low-Frequency Transformer is a solution for use in a small office or home office. It typically includes MOSFET-based inverters that operate from 12V or 24V lead-acid batteries. Higher battery voltages are required to limit operating currents in higher power-rated systems. Batteries may be external or internal to the UPS. Car batteries are used externally and sealed lead-acid batteries internally.
