LIAC600-MS LI-ION Battery Charger

Product Announcement from Analytic Systems


LIAC600-MS LI-ION Battery Charger-Image

This COTS DC Charger is designed for recharging the SAFT Lithium Ion Battery (LBB) used by the US Armed forces from a 24V DC source such as a HmmWV, and is controlled using industry standard interface circuitry. It can also be used in Bypass Mode as a Stand-Alone DC-DC voltage converter. It is designed to deliver 32.0 VDC at up to 22 amps continuous to recharge the battery. The output changes to 28 VDC at up to 22 amps continuous when operating in Bypass Mode.

The LIDC600-24-28 is designed to be powered from a 24V vehicle source. It features low voltage shutdown circuitry that turns it off during vehicle cranking or if the vehicle battery becomes discharged. The unit is designed to meet MIL461E for both radiated and conducted emissions. It is designed to meet MIL810F for shock and vibration and to withstand submersion in 50cm of water for up to 5 minutes.

The unit can be operated over a temperature range of -40 to +60 degrees Celsius, and with an optional pre-heater, will operate at temperatures down to -55 degrees C.

The unit has indicators to show that it is running, when it is charging, input undervolt, output undervolt and over temperature. These indicators are dark except when the display button is pressed.

Available options include a carrying handle and various Mil-Spec Connectors. We are confident that you will get many years of reliable service from this DC Battery Charger.

Military Option

Most of the products manufactured by Analytic Systems can be adapted for military use (Commercial Off The Shelf).

We provide four different levels of ruggedization; most often, a product in military use will use the extra-wide temperature range components to allow operation to -55 degrees Celsius.

The printed circuit boards are also protected against condensation and are enhanced with vibration protection that meets or exceeds MIL-STD810F, Method 514-3 and Cat-1 Proc 1.

C.O.T.S. products are designed to meet EMC radiated and conducted emissions MIL-STD 461E.

All C.O.T.S. products are manufactured in accordance with IPC-A-610.
