UNIPOWER Adds New TPCG Model Front-End

As an addition to its PowerCassette® family of 1U front ends, UNIPOWER Corp. (Coral Springs, FL) added a 450 W version available in three output voltages of 12 Vdc, 24 Vdc and 48 Vdc. The TPCG models’ output currents are 30.8 A at 12 V, 16.7 A at 24 V or 9.4 A at 48 V. The units are housed in ultra-

compact cases only 1U-high 1.6 in x 5 in x 10 in (41 mm x 127 mm x 254 mm). They are available as either chassis-mount or hot-swap versions.

A compatible 19 in rack is available to house up to three units and produce 92.4 A at 12 V, 50.1 A at 24 V or 28.2 A at 48 V. The supplies may also be operated in a 2+1 redundant mode, and have output OR-ing diodes, which result in glitch-free, hot-swap operation to provide continuous power to the load.

Other operating features include a universal 85 Vac to 264 Vac input-voltage range, power-factor correction and a Class B EMI filter. The units have an auxiliary +5 Vdc, 250 mA output; an integral LED status indicator; active current sharing; and no minimum load requirement.

Control and monitoring features include enable/inhibit inputs; ac power fail, dc power good and over-temperature logic outputs; and an analog current monitor output. An optional I²C serial data output is available for monitoring operating functions. Protection features include overload, over-voltage and over-temperature protection.

Availability for the TPCG front-end modules is stock to four weeks. Pricing for the power modules is $225 in volume. The racks are ordered separately.
