DA698-IP66: IP66 Weather-resistant 12V 4A DC PSU with integrated UPS and monitoring
These power supplies accept a mains voltage input of 230VAC @ 50Hz (+/- 10%) and will provide an output of 12VDC (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 9.5VDC, for example after an extended mains failure when standby battery has been depleted, the battery terminals will disconnect. When unit voltage recovers (when mains power returns) the battery terminals will reconnect, allowing battery recharge. This feature allows batteries to provide unit standby 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.
4A fused output
These units can provide up to 4A of 12VDC continuously and are protected with a 4A glass fuse.
Integrated UPS 7Ah VRLA Battery back-up
A 7Ah VRLA battery 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 as required and provide continuous, uninterrupted power to the output from the battery if mains power is unavailable. Batteries are not included. This unit can be used with or without batteries fitted.
In the event of prolonged mains power failure and if the connected VRLA battery has been depleted of useful power, the battery will be automatically disconnected to protect against deep cyclic damage from deep discharging. When mains power is restored, the battery will automatically be reconnected and float-charged ready for use.
ABS IP66 Weather-resistant enclosures
The IP66-rated ABS enclosure is ideal for commercial, industrial and outdoor environments.
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 230VAC
Designed to operate on UK standard mains power, this unit accepts 230VAC @ 50Hz (+/- 10%)
