Cranford Controls 400 BM Series 12v 4A Switch Mode Power Supply Enclosure Holds 1x 18Ah Batteries
These are high efficiency, cost effective Switch Mode Power Supplies, with Mains and Battery Monitoring and two independent volt free fault outputs, ideal for use in Access Control and general PSU applications. They also feature a regulated 13.8V dc output supplying continuous full rated current to load and a universal mains voltage input.
Standby battery recharging is achieved within 24h for an 18Ah battery. Maximum battery life is assured using deep discharge protection to prevent premature battery failure when operating in standby mode for extended periods. Two sets of volt free contacts are provided to signal (i) loss of mains and (ii) battery and loss of output faults.
