Power Supplies

VESDA-E STX PSU 2A 24AH

These are the deeper units designed for installation with a VESDA-E VEU detector (at all fan speeds). The internal charger is EN 54-4 certified and is rated to provide a 3A continuous 24Vdc supply.

VESDA-E Power Supply Units are uniquely designed to complement the style and appearance of VESDA-E aspirating smoke detectors (ASD) and are technically matched to provide sufficient current and battery charging capacity to meet the requirement of EN 54-4.

The STX variants are VdS approved and CE marked to EN 54-4 so are particularly suitable for use in territories where these approvals are required. They may also be suitable in territories where ISO 7240-4 is required.
