Unipower Announces the PowerCassette Switching Power Supply
Unipower Corp. (Coral Springs, FL) recently announced the debut of its new PowerCassette multi-output switching power supply that employs a cellular, rather than modular architecture. Unipower claims that this new type of architecture allows quick factory programming of outputs to meet virtually any requirement. The unit provides up to six outputs, including a 5Vdc, 1A independent standby. Maximum continuous power is 600W, and available output voltages are from 1.2Vdc to 24Vdc.
Significant features of Unipower's new PowerCassette include a case measuring 1.6" x 5.0" x 11.0", giving 6.8W per-cubic-inch power density. Integral ball bearing fans cool the unit, which includes a single input/output connector for hot-swap applications, output Oring diodes and single-wire current-sharing. Power factor correction, Class B EMI input filter, remote sensing, worldwide ac input range, no minimum loads and adjustable outputs are all standard features built into the product. Unipower reports that, with the exception of power components, the PowerCassette consists almost entirely of high-density, surface-mount components.
Optional features on the PowerCassette include an I2C serial data bus output for real-time monitoring of output voltages, output currents, internal temperature and fan speeds. This feature interfaces with the host system through an available standard 1U, 1+1 redundant rack, or directly from the output connector on the power supply.
PowerCassette's architecture employs four standard internal power cells: one for the input filter, rectifier and power factor converter, and then three others for pre-configured single- and multiple-output dc/dc converters. The power cells provide two high-current, one medium-current and two low-current outputs.
Pricing for the PowerCassette in OEM quantities begins at $399 each. Delivery is in 5 to 10 days for prototype quantities and 8 to 10 weeks for production quantities.
