Background

This project involved the installation of an EverExceed PL3 RM6KL Online UPS with a 192VDC high-voltage lithium battery system for PBA / PBAPP's wastewater treatment plant in Malaysia. The system provides uninterrupted power to essential loads, including emergency power and lighting equipment.

Featuring online double-conversion technology, the UPS continuously regulates and filters input power to deliver stable AC power. It provides seamless battery backup during mains failure and automatically switches to bypass mode during overload or inverter faults, helping ensure reliable power supply to critical equipment.
