High-quality, reliable LCM series units boast a comprehensive set of industrial and medical safety approvals

MUNICH, Germany. – Today at Electronica, Emerson Network Power, a business of Emerson (NYSE:EMR) and a global leader in enabling Business-Critical Continuity™, launched two new models in the popular LCM series of AC-DC power supplies, which is known for providing high efficiency and reliability at a competitive cost.

With the addition of the LCM300 and LCM1500, rated for 310 W and 1,500 W loads, alongside the existing 600 W LCM600 unit, Emerson Network Power’s LCM series can now provide for a very wide range of AC-DC embedded power requirement. Featuring high build quality with robust screw terminals, long life, and typical full-load efficiency of greater than 91 percent, 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.

In the LCM300 and LCM1500, this quality and performance is offered at a competitive price of $80 for LCM300 and $255 for the LCM1500 in production volumes.

The quality and reliability of the LCM series units are assured through careful component selection, automated production processes and sophisticated circuit design. Variable-speed ‘Smart Speed’ fans draw on software controls developed by Emerson Network Power 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 LCM300 and LCM1500 units is greater than 500,000 hours, and the units carry a manufacturer’s warranty of three years.

A sophisticated digital control loop optimizes efficiency across a wide load range. The efficiency of both the LCM300 and LCM1500 is greater than 91 percent at full load (230 Vac nominal input), and is at least 80 percent at all loads higher than 25 percent. Power factor correction is implemented internally, offering a typical power factor of 0.99 (LCM1500) or 0.98 (LCM300).

Both units accept operating inputs between 90Vac and 264Vac. Maximum input current for the LCM300 is 5 A, and 18 A for the LCM1500. The compact LCM300 has a power density of 6.86 W/in3, and the LCM1500, 12 W/in3.

Both the new LCM series units will be available in versions offering 12, 15, 24, 36, and 48V outputs; the LCM1500 additionally offers a 28 V unit. All output voltages can be trimmed to ±20 percent (LCM300) or ±10 percent (LCM1500) of their nominal value, which means that almost any output voltage between 10 and 53 V can be provided by LCM series parts.

The LCM300 and LCM1500 safety certificates include UL (60950-1, 508/1598/1433, and 60601-1 Ed 3); CSA (60950-1); VDE (60950-1 and 60601); China (CCC); and CB Scheme international certification. The power supply meets EMI Class B and EN61000 standards for conducted noise and the Restriction of Hazardous Substances (RoHS) 2 directive.

The LCM300 and LCM1500 are being demonstrated at the Electronica exhibition (Munich, 13-16 November) on Emerson Network Power’s stand B2.161.

High resolution photos of the LCM300 and LCM1500 are available.
