GCS Series AC-DC Power Supplies 150/180/250 Watts * Convection/Forcedcooled Ratings * Universal 85 264 VAC Input * IT & Medical Safey Approvals (Class I & II) * < 0.5 W Standby Power (150 & 180 Models) * 40 C to +70 C Operation * Remote On/Off (R Models) * Class B Emissions * 3 Year Warranty The GCS Series has been designed to minimise the no load power consumption and maximise efficiency in order to facilitate equipment design to the latest environmental legislation. Dimensions: GCS150/GCS180/GCS250: 5.00 x 3.00 x 1.42" (127.0 x 76.2 x 36.3 mm) (C): 5.50 x 3.48 x 1.70" (139.7 x 88.5 x 43.2 mm) (TF): 5.50 x 3.48 x 2.20" (139.7 x 88.5 x 57.8 mm) (EF): 6.35 x 3.48 x 1.70" (161.3 x 88.5 x 43.2 mm) Approved for Class I and Class II applications, this range of single output AC-DC power supplies are packaged in an industry standard 3.0" x 5.0" x 1.42" package and achieves EN55011/22 Level B emissions compliance whilst maintaining very low earth leakage currents, making them suitable for a wide range of 1U and other industrial, IT and medical applications. The series has single output versions from 12 V to 48 VDC, dual-fusing for compliance with IEC60601-1 and feature minimal excess heat generation as efficiencies reach 94%. They will deliver up to 250 W of power over an operating range of -40 C and up to +70 C and are available with a number of cover options.

Temperature should be monitored using K type thermocouples placed on the hottest part of the component (out of direct air flow). See Mechanical Details for component locations. Temperature Measurements (At Ambient 50 C) Component Max Temperature C T1 Coil 120 C L3 Coil 120 C Q1 Body 120 C Q3 Body 120 C C6 105 C C23 105 C -- Service Life The estimated service life of the GCS Series is determined by the cooling arrangements and load conditions experienced in the end application. Due to the uncertain nature of the end application this estimated service life is based on the actual measured temperature of a key capacitors with in the product when installed by the end application. The worst case of the two figures should be taken as the indicative service life in 24/7 operation. The graph below expresses the estimated lifetime of a given component temperature and assumes continuous operation at this temperature.
