75W switching regulated power supplies are convection cooled
Expanding the Narrow Profile, three-day power supply series of switching regulated power supplies, Acopian Power Supplies introduces the the WN8B power supply. The AC-DC single-output units provide an output power of up to 75W with convection cooling, which eliminates the need for fan maintenance, along with audible/ambient noise and vibrations.
The modules measure 1.7x3.5x8.8" and can therefore be mounted in tight spaces where most standard units do not fit.
In addition to their narrow profile and small footprint, the WN8B power supplies' current limiting capabilities make them ideally suited for a range of applications in which high inrush loads are used. They are most commonly employed in industrial automation, high-power LED lighting, test and measurement equipment, broadcast equipment, gaming and point-of-sale equipment and IT equipment as well as in communications, motor control power and motorised entrance gates, shades and blinds.
Acopian's WN8B power modules operate from a universal input of 90-265VAC (49-420Hz, single phase) or 110-350VDC. They are offered with PFC of 0.99 at 115VAC (60Hz and full load) to ensure compliance with EN61000-3-2. Units are available with 39 output voltages from 3.3 to 125V, and with a ±0.5V or ±1V user-adjustment range. The output voltage may be controlled by an external 1kΩ potentiometer.
The modules operate over a temperature range from 0 to +71°C with power-saving efficiency up to 81%. A green LED output indicator is lit when the supply is on (DC). Modules are CE Marked and feature general-purpose safety agency certifications per UL60950 and UL508. The series further meets the conducted and radiated EMI requirements of EN55022, Class A.
A metal case fully encloses all circuitry and provides EMI shielding, while an AC input filter attenuates both common and differential mode noise conducted to the line. The WN8 power supplies are delivered with threaded mounting holes to permit mounting to a chassis, cabinet wall or bracket. Units may also be used on a test bench or tabletop. Accessory mounting kits for wall mounting or DIN rail mounting are available.
