VESDA-E Power Supply Units are uniquely designed to complement the style and appearance of VESDA-E aspirating smoke detectors (ASDs) 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 certified and CE marked to EN54-4 so are particularly suitable for use in territories where these approvals are required.
The VPS-250-STX-SLV are the deeper silver 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.
There is space for up to 24Ah batteries (not provided). The unit also provides a non certified setting which enables it to power loads up to 3.4A while recharging batteries up to 24Ah in accordance with EN 54-4.
