The BPH series of ½- and 1-W switching power supply modules are drop-in solutions that comply with CSA CAN3-C235-83 for Canada as well as Australia and other 347-Vac mains input countries. With an input range from 100 to 375 Vac. It is a one-component solution with a patented circuit design, incorporating a custom ASIC, and eliminates line EMI requiring no external input filtering.
The power module suits low-power and standby mode requirements in smart building applications when operation from 277- and 347-Vac circuits are needed. The modules provide constant voltage, constant power regulation from an 8 or 14 Vdc primary output, and can drive capacitive loads, including supercaps, relays, solenoids, SSRs, indicating lights, op-amp drivers, zero-crossing detectors and RF/powerline-carrier transceivers. Additionally, it can be a source for isolated dc utility power. (From $7 ea/large qty available now.)
