The BPW 4 handles the widest possible load variations and has a no-load power consumption of less than 30 mW. Its unique “constant power” mode delivers maximum usable power when pushed, so it actually outperforms many constant current circuits. In addition, the BPS 4 output power does not degrade over the operating temperature range (-30 to +70° C). Regulatory approvals are greatly simplified as the patented* circuit design also effectively eliminates line EMI, so that no input filtering is required.
Meets EN 55022, Class B; FCC Part 15, Class B as well as UL/CSA and EN Product Safety (ITE).
The BPW 4 Power Supply Module is an ideal solution for numerous control applications in lighting, sensing, smart building and power distribution where operation from 277VAC mains is required. This low-cost supply provides up to four watts of output power at 8, 14 and 24 VDC (Vo) and optional 3.3 and 5.0 VDC (Vr) output for microprocessors, logic, timing circuits, transceivers, sensors or other control functions. The Bias Module is an immediate “drop-in” solution, requiring no additional external components. At just 1.90 x 1.31 x 0.98 inches (48.3 x 33.3 x 24.9 mm); with a volume of just 2.45 in3 (40.1 cm3), the BPS 4 is a real space saver.
Extremely rugged construction (rated to IP66), makes the BPW 4 well suited for portable and harsh environment applications. Because it is a ready-to-apply solution, use of the BPW can shorten the design cycle and eliminate the need to source and inventory multiple power supply components. And as a single-component solution, with >500,000 hours MTBF, the module can greatly improve product reliability, while eliminating the need to source and inventory dozens of discrete components.
