Acopian Introduces AC-DC Mini Encapsulated Linear Power Supplies

October 29, 2006 by Jeff Shepard

Acopian Power Supplies introduced its EB family of encapsulated modules that have series regulated outputs ranging from 1 to 75V and as high as 2.5A. Their footprint is only 3.5 x 2.5 inches. Output power range is 0.5 to 14W. These modules have a thermal barrier running through the power supply, isolating the hot running components from the more sensitive components. All models are UL recognized. Modules have a universal input range of 105-125 Vac, 47 to 420 Hz, single phase. Line and load regulation are, respectively ± 0.2% to ± .05% and ± .05% to ± .25%. Input-to-output isolation is 3000Vac. Output ripple/noise is1mV. All models may be used in series and are short circuit (continuous) protected.

Operating temperature range is -20 to +71°C. without derating. Storage temperature range is -55 to +85°C. Connecting an external resistor to the T/C terminal allows the user to trim the output precisely to the nominal voltage. The temperature coefficient for 9 to 75V output ranges is typically 0.015%/°C. For 1 to 8V, the temperature coefficient is 0.03%/°C. Output impedance is 0.07Ω at 1kHz and 0.2Ω at 10kHz (approx.). Linear operation minimizes output noise so these modules are well-suited for use in test equipment, analog systems, controls, aviation and R&D.
