VESDA VPS-300US-220

Product Overview

The VESDA VPS-300US-220 is a high-capacity power supply designed to provide reliable 24VDC operating power and supervised battery backup for VESDA and VESDA-E aspirating smoke detection systems. Engineered for critical fire protection environments, this unit delivers stable, power-limited outputs and supports multiple detectors and accessories across the Xtralis product range.

Designed to accept 120VAC or 220VAC (60 Hz) input, the VPS-300US-220 automatically regulates power across three independent, power-limited 24VDC outputs, ensuring consistent performance. The unit also features full battery supervision and an intelligent charging system that maintains sealed lead-acid or gel-type standby batteries for uninterrupted operation.

Paired with the included VBC-001 battery cabinet, the VPS-300US-220 supports up to six backup batteries, extending autonomy for applications requiring long standby times. Built to meet UL fire alarm power supply requirements, it is suitable for indoor dry environments and installations governed by NFPA 70, NFPA 72, and local AHJ standards.
