A complete 12V DC power supply and UPS battery backup in one compact enclosure. When operating from 240V, it automatically charges the internal battery (available separately) and powers the connected load (max 5A). When mains fails, the load switches and is powered from the battery. Recommended battery is 7.2Ah 12V (S4540).
Features output short circuit protection, output current limiting and over voltage protection. Separate battery charging circuit with fast changeover and standby battery low voltage cutoff (10V). Screw terminal connections. Ideal for alarm backup use. Indoor use only. Not be used to drive LEDs directly. This may overload the unit and cause damage.
Note: not suitable for LiFePO4 type batteries. Not be used to drive LEDs directly. This may overload the unit and cause damage.
