Bias Power BPH AC-DC Power Supplies

Bias Power BPH AC-DC Power Supplies are available in 1/2W and 1W with universal input and more than 500,000 hours mean time between failures (MTBF). These drop-in modules feature less than 30mW no-load input power and no derating across the entire temperature range of -30°C to +70°C. Bias Power BPH AC-DC Power Supplies use patented technology that does not require extra filtering or shielding because there is very little EMI / EMC interference with other circuits. These single- and dual-output power supplies measure 27.94mm x 23.24mm x 13.97mm. These devices create very little self-generated heat, making them ideal for intelligent devices such as smart sensors, meters, lighting, and grids, machine to machine (M2M), Internet of Things (IoT), and other control applications.
