NEW 1U, HOT-SWAP FRONT ENDS ACHIEVE

15 WATTS PER CUBIC INCH POWER DENSITY

Coral Springs, Florida-UNIPOWER's new PCP/TPCP front ends are designed to drive power buses for distributed power systems. Three different models produce 48VDC at 25A (1200W), 24VDC at 41.7A (1000W), and 12VDC at 66.7A (800W). The units come in an ultra-compact case only 1U high (1.6 inches or 41mm) by 5 inches (127mm) wide by 10 inches (254mm) deep, resulting in up to 15 watts per cubic inch power density. They are available in either hot-swap or chassis-mount versions and have self-cooling fans and a single, pluggable connector. The PCP/TPCP Series is a member of UNIPOWER's popular PowerCassette® family of switching power supplies.

These front ends operate from 85 to 264VAC universal inputs and feature power factor correction together with a Class B input EMI filter. Other features include a 5VDC, 250 mA auxiliary output, integral LED status indicators, active current sharing, an output ORing diode and no minimum load requirement. Control and monitoring features include enable/inhibit inputs, AC power fail, DC power good and overtemperature logic outputs; and a current monitor output. An optional I²C output is available for monitoring operating functions in serial data format. Standard protection features include overload, overvoltage and overtemperature protection.
