The BPW-4 series micro-size switching power supplies offer single or dual outputs. The 1.90 x 1.31 x 0.98-in. supplies operate from 85 to 308 Vac at 50/60Hz. The supplies provide up to 4-W output power at 8, 14 and 24 Vdc and optional 3.3 and 5.0 Vdc outputs for microprocessors, logic, timing circuits, transceivers, and sensors.
The switching power supplies have a no-load power consumption <30 mW. The constant power mode delivers maximum usable power and does not degrade over the operating temperature range from −30 to +70C. The circuit design eliminates line EMI and needs no input filtering. The supplies suit control applications in lighting, sensing, smart building and power distribution where operation from 277 Vac mains is required. (Contact company for pricing and availability.)
