Bias BPSX/BPWX/BPHX series of miniature ac-dc power supply modules have an extended full power operating range from -40 to 85°C. They are an ideal drop-in solution for a variety of low-power and standby mode applications that must operate in harsh temperature environments. Their patented design eliminates the need for EMI filtering and results in the smallest, highest efficiency turn-key solution available. The modules are regulatory ready and can significantly reduce your design time while speeding time-to-market and simplifying the supply chain from dozens of components to a single part. They offer voltage-regulated output which has a constant power mode instead of a conventional current limit. This output is best suited to drive mechanical relays, solenoids, SSRs, capacitive loads, indicating lights, LEDs and as a source for isolated DC utility power which may be used directly or post-regulated with either a linear regulator or a DC/DC converter.
