Vesda Xtralis VPS-250-STX5 VESDA-E STX Power Supply Unit 2A 24Ah
The VESDA-E Power Supply Units are designed to complement the style and appearance of VESDA-E aspirating smoke detectors (ASDs) while providing sufficient current and battery charging capacity to meet EN 54-4 requirements.
The STX variants are VdS certified and CE marked to EN 54-4, making them ideal for use in regions where these approvals are required. Designed with the same width, curved profile, and styling as VESDA-E detectors, these power supplies integrate seamlessly with the detectors. An internal channel allows the 25mm exhaust pipe to be routed back to the protected area, supporting back-venting when needed.
