Emerson Network Power has launched two new models in the popular LCM series of AC-DC power supplies, known for providing high efficiency and reliability at a competitive cost. With the addition of the LCM300 and LCM1500, rated for 310- and 1,500-W loads, alongside the existing 600-W LCM600 unit, Emerson Network Power's LCM series can now provide for a wide range of AC-DC embedded power requirement. Featuring high build quality with robust screw terminals, long life, and typical full-load efficiency > 91%, these units are well suited for industrial and medical applications. They are backed by a comprehensive set of industrial and medical-safety approvals and certificates.
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. 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% at full load (230-V AC nominal input), and is at least 80% at all loads higher than 25%. PFC (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 90 and 264 V AC. The 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 48-V outputs; the LCM1500 additionally offers a 28-V unit. All output voltages can be trimmed to ±20% (LCM300) or ±10% (LCM1500) of their nominal value, which means that LCM-series parts can provide almost any output voltage between 10 and 53 V. 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 series AC-DC power supplies are available for $80 (LCM300) and $255 (LCM1500) in production volumes. Emerson Network Power LCM300 product deeplink LCM1500 product deeplink
