Battery Power - September/October 2012 - (Page 27)

Power Supplies (larger than 1 W multiples) allowing the singles to meet the ErP requirement of 87 percent and 500 mW. Designed for convection and cooled applications, the GRN series operates from 0°C to 70°C with suitable derating above 50°C. 40-Watt DC/DC Converter with a 2:1 Input GRN Series of Green Power Supplies Power Sources Unlimited, Inc. has released the new GRN series of “green” power supplies. Available in both single and multiple output versions, these energy efﬁcient component power supplies cover the 45, 60, 80, and 110 watt power levels. Complying with the energy saving requirements of the ErP (Energy Related Products) Directive, the single output versions offer high efﬁciency, high power density and low standby power. The multiple output versions are available with up to four outputs and also offer high efﬁciency and low no-load input power in a compact, low proﬁle package. The GRN series is well suited to a broad range of medical, information technology, and industrial applications and is designed for those seeking to reduce standby and overall power consumption. Offering 17 standard models at each power level, the GRN series offers a ﬂat efﬁciency curve from 25 percent to a 100 percent load. The use of innovative design techniques result in more than 87 percent average efﬁciency for the singles (12 V to 48 V) and 85 percent for the multiples (3.3 V and 5 V outputs also available) while featuring less than 300 mW standby power ConTech, a Division of Calex, has released the TMH series of DC/DC converters. The TMH series offers up to 40 watts of fully regulated output power with an industry standard 2 inch by 1 inch footprint. The series offers a 2:1 input range with nominal input voltages of 12 VDC, 24 VDC and 48 VDC. Single outputs offered are 3.3, 5, 12, and 15 VDC. Dual outputs are +/-12 and +/-15 VDC. The TMH series operates with efﬁciencies as high as 92 percent. Features include Remote On/Off, Output Trim and Short Circuit Protection. The operating ambient temperature range of the TMH is -40°C to 55°C with no de-rating. The non de-rated temperature range can be extended to 65°C ambient with an optional heat sink. The unit is encapsulated with a thermally conductive potting compound in a six-sided metal case for improved thermal performance in still air environments. The TMH series is RoHS compliant. www.BatteryPowerOnline.com September/October 2012 • Battery Power 27 http://www.ThermalNews.com/conferences http://www.BatteryPowerOnline.com
