DA488: 12V 4A DC PSU with integrated UPS & 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 is resumed) 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.
