The EP-352 is a high-performance 24 V emergency power management system, specifically designed for use in public address (PA) and emergency communication systems. Housed in a durable 48,3 cm ( 19 inch ) rack-mount enclosure (3U), it features premium components to ensure long-term operational reliability.

The unit provides regulated charging of 24 V lead-acid batteries, with electronic protection against overcharging, reverse polarity, and overvoltage. A clear LED display shows the charging status in percentage steps, allowing for quick monitoring of power reserves. The standard EP-352 switches to backup power upon receiving a signal from the PD-322 A power distributor.

In its advanced version, the EP-352 RM, the system includes automatic switchover and an integrated deep discharge protection, which disconnects the battery when voltage drops below the safe threshold—protecting battery health.
