12v battery backup

12V Lead-Acid Battery Chargers

L12-0.5/115AC 115/230VAC input, 0.5A output, 0C to +40C operation, 1yr. limited warranty. Designed for low-cost charge maintenance of 12V batteries 1.3Ah or larger. This unit is especially economical in OEM quantities. $55 (1-4).

This is a bare-board 2 mode linear charger/power supply. Two charger-status output signals are available to power front-panel LEDs. Short circuit and reversed-battery protected.

The output voltage is temperature-compensated and may be field adjusted. Mating connectors are not supplied with this charger. As a convenience, a connector kit is available.

Data Sheets and Operation Instructions

S12-1.0/115AC 115/230VAC input, 1.0A output, -40C to +65C operation (full output), to +85C (reduced output), 5yr. limited warranty. For 12V, 6Ah or larger batteries. Designed for extreme environments. $78 (1-4).

This is a microprocessor-controlled, enhanced 3 mode, bare-board switchmode charger/power supply. A charger status output signal is available to power a front-panel LED. Short circuit and reversed-battery protected.

The output voltage is temperature-compensated and may be field adjusted. The charger can also be interfaced to a remote temperature monitor (LM335) for applications that put the battery in a different environment from the charger. Mating connectors are not supplied with this charger. As a convenience, a connector kit is available.

Data Sheets and Operation Instructions

L12-1.5/115AC 115/230VAC input, 1.5A output, -40C to +60C operation, 5yr. limited warranty. For 12V, 4.5Ah or larger batteries. $89 (1-4).

This is a microprocessor-controlled, enhanced 3 mode, open-frame linear charger/power supply. It features two available charger-status signals that can power front-panel LEDs.

The output voltage is temperature-compensated and may be field adjusted.

Data Sheets and Operation Instructions

L12BD-1.5/115AC 115/230VAC input, 1.5A output, -40C to +60C operation, 5yr. limited warranty. For 12V, 4.5Ah or larger batteries. With low battery disconnect. $109 (1-4).

This is a microprocessor-controlled, enhanced 3 mode, open-frame linear charger/power supply. It features two available charger-status signals that can power front-panel LEDs.

The output voltage is temperature-compensated and may be field adjusted. An automatic low-battery load disconnect circuit protects the battery from becoming over-discharged.

Data Sheets and Operation Instructions

PCB-S12UPS-3.0/12DC 12VDC input, 12VDC 3.0A output. -40C to +65C operation. For 12V 5Ah or larger batteries. With low battery disconnect. $91 (1-4).

This is a bare-board unit that operates from a large range of DC supply voltages. The input supply is switched to the output terminal to power a load (up to 3.0A).

An on-board buck/boost low-current charger maintains an external, user-supplied, 12V battery. In the event of a power failure, solid-state switches connect the 12V battery to the unit's output.
