EPS Emergency Power Supply

The EPS three-phase emergency power supply is a power supply device that provides emergency power for various 380V/220V electrical appliances and equipment, including primary loads, important loads, fire protection facilities, fire emergency lighting, or other loads, and can be used as a second or third power source.
When the mains power is normal, the mains supplies power to the load through the automatic transfer switch, while the charger performs intelligent charging of the backup battery. When the mains power fails or exceeds 20% of the normal voltage, the controller provides an inverter signal to start the inverter power supply, and the automatic transfer switch immediately switches to the inverter output to continue providing sinusoidal AC power. When the mains voltage returns to normal, the emergency power supply will automatically restore grid power supply.
