DA371: 12V 1.5A DC Steel-cased power supply with integrated UPS, mains-failure and low-battery monitoring
This simple range of multi-purpose metal-cased power supplies provides 1.5A of 13.7V DC via a fused output, for 12V DC equipment. The enclosure can also house a 7Ah VRLA battery, which the power supply will automatically charge while mains power is present, and use in the event of a mains power loss.
Manufactured and tested in Britain, this range of power supplies has a five-year warranty, allowing installers to fit and forget. It is ideal for where high reliability is required and where companies may have long service or maintenance contracts. Typical uses include powering door access controllers, electronic door releases, magnetic locks and CCTV cameras.
1.5A 12V DC fused output
This output can provide 12V up to 1.5A DC continuously and is protected with a quick-blow
2A glass fuse.
Integrated UPS battery back-up function
A 7Ah VRLA battery can be placed in the mild steel enclosure and connected to the battery terminals of the PCB. This power supply will automatically float-charge the battery to capacity, providing continuous uninterrupted power from the battery if mains power is unavailable.
Batteries are not included. This unit can be used with or without batteries fitted.
Mains failure signalling
If the mains-input power is not detected for approximately 30 seconds, the mains-fail
relay will change-over. The delay helps prevent false triggering during common power fluctuations within the national grid. The clean normally open-circuit (N/O) & normally-closed-circuit (N/C) relay contacts can be used to switch or signal other systems.
Low-battery signalling
Should the connected VRLA battery be nearing depletion, the Low Vol
relay will change-over. The clean N/O & N/C relay contacts can be used to switch or signal other systems.
Mild steel powder-coated enclosures
Precision-made from mild steel and powder-coated white for an easy-clean, durable finish, this enclosure is ideal for wall mounting. The enclosure includes knock-outs
for cable gland entries.
Includes a spares-bag
mounting kit
Each unit includes a spares-bag for the installation engineer. This kit contains useful items, such as cable glands, wall plugs and fixing screws.
Input 230V AC @ 50Hz (+/- 10%)
Designed to operate on UK standard mains power, this unit will accept a mains-powered input of 230V AC @ 50Hz (+/- 10%)
