Product Introduction

This emergency supply combines a charger, battery bank, inverter or DC distribution, automatic transfer logic and protected outgoing circuits in one monitored system. Unlike a general UPS serving connected equipment, it is arranged around defined emergency loads such as egress lighting, intercom, access release and control circuits. A front mimic display shows source, battery, output and fault conditions.

Key Features

Dedicated outgoing feeders separate emergency loads from normal branch circuits.

Automatic transfer logic energizes the backup path after loss of the monitored source.

The charger maintains the battery and reports low-voltage or battery fault conditions.

A mimic panel displays normal source, standby source and feeder status clearly.

An external maintenance bypass can preserve supply during cabinet service.

Customer Product Concerns

Emergency circuits must start reliably, remain clearly segregated and reveal battery or charger faults before a real supply failure.

Emergency and normal loads are mixed in one unmarked panel.Dedicated labeled feeders and separated terminals preserve circuit identity.

A failed charger remains unnoticed until the battery is needed.Continuous battery and charger supervision activates visible and remote alarms.

Transfer delay disrupts sensitive control circuits.The selected inverter or DC architecture matches the continuity requirement of each load.

Servicing the battery cabinet removes all emergency power.An optional maintenance bypass or alternate input supports planned work.

Typical Applications

Cleanroom emergency lightingDoor-release and intercom backupCritical alarm circuitsSelected ventilation controls
