VESDA-E Power Supply Units are purpose-built to match the look and performance of VESDA-E aspirating smoke detectors, delivering the current and battery charging capacity required to meet EN 54-4 standards.

The STX variants are VdS certified and CE marked to EN 54-4, making them ideal for regions where these approvals are mandatory.

These compact, shallow units are designed with dimensions that align with VESDA-E detectors for a consistent installation profile.

Internally, they feature an EN 54-4 certified power supply providing a continuous 0.5A at 24V DC while charging batteries (not included) in 7Ah, 12Ah, or 14Ah configurations.

They support 24-hour standby plus 30 minutes in alarm for VESDA VLF-500, VESDA-E VEP, VESDA-E VES, and VESDA-E VEU detectors (up to fan speed 5).

A non-certified mode is also available, allowing loads up to 1A while charging batteries up to 12Ah in compliance with EN 54-4.
