The VESDA-E Style E Power Supply is designed to power larger ASD units, including the VESDA-E VEU (all fan speeds) and VESDA-E VEA detectors. It is also suitable for installations with multiple detectors and/or remote displays.
The internal charger is EN54-4 certified, supporting loads up to 3 A and batteries up to 38 Ah. Uniquely, the unit can provide four separately fused outputs, ideal for powering multiple detectors or disparate loads. This versatile unit delivers a combined 24V DC load of up to 3 A.
The front cover features two LEDs providing visual indication of healthy (OK) status or fault conditions, while multiple knockouts allow convenient cabling access to detectors, remote displays, or subracks.
