Vesda Xtralis VPS-220-STX5-SLV Power Supply 0.5A 7-14AH PSU-STX - Silver
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. Style STX Product Range Designed with the same widths and styling of the VESDA-E detectors, these power supplies geometrically blend with the VESDA-E detectors.
- Description
They feature the same curved profile and also incorporate an internal channel which accommodates the exhaust of the VESDA-E detectors. This is particularly useful when it is necessary to run the 25mm exhaust pipe back to the protected area (back-venting).
The units are available in two colours; Matt black is standard and works in harmony with the finish of the black plastic VESDA-E detectors (the “–P” variants) or contrasts with the extruded aluminium finish of other variants.
Alternatively, the unit can also be supplied with a grey (RAL 7047) cover which complements* the extruded aluminium finish of the premium VESDA-E Detectors.
VPS-220-STX5 & VPS220-STX5-SLV: 0.5A load with 14Ah batteries (max)
These are the shallower units in the range with depth and width matching the VESDA-E detectors.
Internally, they provide an EN 54-4 certified Power Supply rated to provide a 0.5A continuous 24Vdc supply whilst also charging the batteries (not supplied) which can be a 7, 12 or uniquely, 14Ah arrangement.
As such the unit can be used with confidence to power, and provide 24hr standby (plus 0.5hr in alarm), for the VESDA VLF-500, VESDA-E VEP & VESDA-E VES detectors and also the VESDA-E VEU detectors up to fan speed 5.
The unit also provides a non-certified setting which enables it to power loads up to 1A while recharging batteries up to 12Ah in accordance with EN 54-4.
