Low-Cost Single-Voltage Supplies Have 25-W Outputs

The six members of the GE-25 series of general-purpose, low-cost, highly reliable power supplies feature single-output voltages from 3.3 to 48 V dc with a ±10% adjustment range. The 25-W supplies accept inputs of 88 to 264 V ac (125 to 373 V dc). Efficiency averages 81% and the series’ no-load power consumption of less than 0.5 W enables environmentally sound designs. The rugged and compact supplies are made with 105°C long-life capacitors and have an operating range of ?20°C to 70°C. They have been vibration tested to 5g. Circuit-protection capabilities include short-circuit, overload, over-current, over-voltage, and low ac input “brown-out” protection. The supplies are UL60950-1 and TUV EN60950-1 safety approved and comply with EN55022 Class B standards for both radiated and conducted electro-magnetic interference. The GE-25 power supplies cost $11.96 each in OEM quantities. Delivery is from stock to eight weeks. POWER SOURCES UNLIMITED INC., Wrentham, MA. (800) 966-7784.
