Description
Waveform Generation: It controls the MOSFET switching to produce a Quasi-Sine Wave (or Square Wave depending on the specific ECO model) during battery mode.
Charging Management: Uses PFC (Power Factor Correction) technology to charge the battery efficiently. it manages a 3-stage charging process and supports “Zero Volt Pick-up” to revive deeply discharged batteries.
Mains Sensing: Continuously monitors input voltage (100V–300V range). It decides when to switch from Mains to Battery mode (changeover time is typically \le 10\text{ms}).
Protection Logic: It monitors for faults and triggers shutdowns for:
Short Circuits
Overloads
Battery Low/Deep Discharge
Phase Reversal
User Interface: Controls the LED display indicators (Mains On, UPS On, Charging, Low Battery, and Overload).
