LCM1000 AC/DC Power Supply

Artesyn Embedded Technologies LCM1000 provides a low-cost solution to industrial and medical single output high power requirements. Full-featured, the 2.4" x 5" x 10" enclosed form factor utilizes smart fans for self-contained thermal management at very low acoustic noise levels. Digital signal processor control allows for a high level of modification flexibility. Voltage output for the series ranges from 10.8 V to 52.8 V at a continuous output power of 1000 W. The LCM1000 also provides an optional 5 V standby, conformal coating, and constant current operation.

The LCM1000 series of power supplies provide for a very wide range of AC/DC embedded power requirements. Featuring high build quality with robust screw terminals, long life, and typical full-load efficiency of greater than 90%, these units are ideal for use in industrial and medical applications. They are backed by a comprehensive set of industrial and medical safety approvals and certificates.

A sophisticated digital control loop optimizes efficiency across a wide load range. The efficiency of the LCM1000 is greater than 90% at full load (230 VAC input) and is at least 80% when loading is higher than 25% of full load. Power factor correction is implemented internally, offering a typical power factor of 0.99.

Variable-speed smart speed fans draw on software controls developed by Artesyn Embedded Technologies to match fan speed to the unit’s cooling requirement and load current. Slowing the fan not only saves power but also reduces wear, thus extending its life.

The MTBF of the LCM1000 unit is greater than 500,000 hours, and the units carry a manufacturer’s warranty of three years.
