A new series of ultra-compact AC/DC power supplies is announced by leading power specialist company Powersolve. The JB300/320 series is available as single or dual output units capable of providing up to 320W. Power factor correction to EN610000-3-2 class A is standard across the range and all models meet all relevant international safety approval standards.

Key to the versatility of the JB300/320 series is the fact that Powersolve offers these power supplies in four different mechanical formats, making them suitable for a wide range of applications where space is restricted. The four options are: An open U-channel unit that provides up to 320W with forced air or up to 180W convection cooled; A U-channel unit with top cover giving a maximum of 170W convection cooled; An enclosed unit with built-in end fan giving up to 320W and an enclosed unit with built-in top fan giving the same 320W maximum. Maximum power density for these units is high at 8.9W/in³.

All models in the JB300/320 series feature an auto-selectable AC input ranging from 90 to 264V and are available as either single output units, with fixed voltages from 2 to 60V DC or with dual output combinations based on 5,12, 24 and 48V. Up to 700W peak power is possible within a 500µs duty duration. Operating temperature range is 0 to 70ºC with derating from 50 ºC.

Features include Power Good and Fan Fail Signals, LED indicator, protection against over voltage, over temperature and short circuit and a 12VDC, 400mA output to drive an external cooling fan is incorporated as standard in the U-channel units.
