DA486: 12V 2A DC Power supply unit with integrated UPS & monitoring

These power supplies accept a mains voltage input of 230V AC @ 50Hz (+/- 10%) and will provide an output of 12V DC (13.7).

Equipped with separate SPCO contacts for mains-fail signalling, these supplies will also house and charge a VRLA battery up to 7Ah capacity.

Battery low-voltage disconnect - If the unit output voltage falls below approximately 9.5V DC, for example after an extended mains-failure when stand-by battery has been depleted, the battery terminals will disconnect. When unit voltage recovers (when mains is resumed) the battery terminals will reconnect, allowing battery recharge. This feature allows batteries to provide unit stand-by without being damaged by deep-discharge during extended mains-failures.

Typical uses include powering door access controllers, electronic door releases, magnetic locks and CCTV cameras.

2A fused output

These units can provide up to 2A of 12V DC continuously and is protected with a quick-blow 2A glass fuse.

Integrated UPS function 7Ah VRLA Battery back-up support

A 7Ah VRLA batteries can be placed within the unit 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.

Low-battery disconnect

In the event of a prolonged mains power failure where the connected VRLA battery has been depleted, the battery will be automatically disconnected to protect against damage from deep discharging. When mains power is restored, the battery will automatically be re-connected and float-charged ready for use.

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.

Mains power input 230V AC

Designed to operate on UK standard mains power, this unit will accept a mains-powered input of 230V AC @ 50Hz (+/- 10%)
