The CUI Inc. VSBU-150-15 is an AC/DC converter designed to deliver a regulated 15 Vdc output at up to 10 A, providing 150 W of output power. It operates from a universal AC input range of 90-264 Vac at 47-63 Hz, with active power factor correction achieving a typical 0.95 PF at 240 Vac full load. The converter offers a typical efficiency of 88%.
Electrical protections include over voltage protection (112% nominal) and over current protection (110% nominal). The unit features a minimum hold-up time of 16 ms at 110 Vac full load and a maximum start-up time of 3 seconds. Isolation is rated at 4,242 Vdc minimum between primary and secondary, and 2,837 Vdc minimum between primary and earth ground, with a minimum isolation resistance of 50 MΩ.
The VSBU-150-15 is packaged in an open-frame, chassis-mount form factor measuring 127.0 mm x 76.2 mm x 35.6 mm. It is rated for operation in 0°C to 70°C ambient temperatures with derating, and storage from -40°C to 85°C. The MTBF is a minimum of 100,000 hours per MIL-HDBK-217F at 25°C ambient.
