480V emergency LED Driver is as follows:

The working principle of main power to UFO Highbay lights with a 480V emergency led driver is as follows:

1. In the old method, a transformer was used to step down the 480V mains voltage to 277-347V before supplying power to the lighting fixtures through the emergency led driver.
2. The current method eliminates the need for voltage conversion, as the emergency led driver directly receives 480V voltage and outputs 277-347V.

Advantages: The new version of the emergency led driver saves the cost of a transformer and the associated installation procedures, saving approximately $30 per unit.
