Designed for standby mode and other low-power supply applications, Bias Power's new BPS micro-size switching power supply allows designers 0,5 or 1 W of power in a 25,4 x 22,3 x 12,7 mm package. Operating at nominal 75% efficiency, applications are widespread; including powering remote and networked sensors, power-line carrier, relay drivers, test equipment, IR receivers, building automation, etc. The BPS, in six models which deliver 8 V or 14 V (single-output), or 5 V and 8 V (dual outputs) from an 85-265 V a.c. input, is also suited to powering system clocks, IR remote receivers, membrane keypads, and LED panel lighting for test equipment, and audio and video equipment. No-load power consumption is less than 30 mW. Bias Power says that it uses a special circuit design to eliminate line EMI so that no input filtering is required. It does this by isolating the input path for the duration of the conducted noise. An attribute of the overall assembly is extremely rugged construction, making the BPS well suited for portable and harsh environment applications.
