Vesda Xtralis Power Supplies


SKU: 88f8de25cf56 Category: Brand:


Xtralis Power Supply Units are uniquely designed to complement the style and appearance of Xtralis 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 Style E variants are VdS approved and CE marked to the EN54-4 so are particularly suitable for use in territories where these approvals are required. It may also be suitable in territories where ISO 7240-4 is required.

VPS-215-E: 0.5 A load / 7 Ah batteries (max)

This is the budget unit within the range. It is intended as a low cost unit to supply a single pipe ASD detector which only requires 7Ah batteries. A simple but elegant construction and no LEDs on the lid keep the cost of the unit to a minimum. This unit is still engineered to compliment the product with cable entry knockouts lining up with the cable entries on various Xtralis detectors including the VESDA VLC and the ICAM IAS and ICAM LAS products. The unit can also be inverted where necessary. The internal charger is EN54-4 approved and internal LEDs are provided to indicate OK (output healthy) and Fault.

VPS-220-E: 0.5 A load / 14 Ah batteries (max)

This is the premier unit within the range. Designed with the same foot print, colour and layout as the VESDA VLP and VESDA VLS, the power supply will visually blend with the detectors. Internally is an EN54-4 approved Power Supply rated to provide a 0.5 amp continuous 24 Vdc supply while also charging the batteries (not supplied) which can be a 7, 12 or uniquely, 14 amp/hr arrangement making it suitable for most multi-pipe ASD systems. With regard to installation, cable entry knockouts all line up with the VESDA VLP and VESDA VLS enclosure allowing positioning of the power supply directly adjacent to the detector. The front cover supports 2 LEDs giving a quick visual indication of OK and/or fault condition.

VPS-250-E: 2 A load / 38 Ah batteries (max)

This power supply is designed for installation with multiple detectors and/or remote displays. The internal charger is EN54-4 approved and there is space for up to 38 Ah batteries. With 4 separate fused outputs, this is a very versatile unit which can deliver to a combined, 24 Vdc, load of up to 2 amps. The front cover supports 2 LEDs to provide visual indication of Healthy status (OK) or fault condition and various knockouts exist to provide convenient cabling access to detectors, remote displays or subracks.
