NEW, 1U HIGH DC/DC CONVERTERS

PRODUCE 12 OR 24VDC AT UP TO 700 WATTS

Coral Springs, Florida- UNIPOWER's new TPCMQ48 Series DC-to-DC converters produce 12VDC at 54.2A or 24VDC at 29.2A; the input voltage is a nominal 48VDC with a wide range of 40 to 60VDC. The compact, self-cooled case is only 1U (1.6 inches) high, 5 inches wide and 10 inches deep, resulting in up to 8.8 watts per cubic inch power density. The units are available as hot-swappable modules with a handle and retention bracket or as chassis mount versions. They have a single pluggable connector for input and output.

These converters are available with a compatible 1U, 19-inch rack that can accept up to three DC/DC modules for higher power or for N+1 redundant operation. The racks are only 12 inches deep and can also be paralleled with other fully loaded racks for added power. The converters can also be used on a stand-alone basis or built into a customer's system.

Other features of this series include LED status indicators, staged pin engagement, an isolated 5VDC 250mA standby output, active current sharing capability, an output ORing diode, and no minimum load requirement. The units also have monitoring and control signals such as output power good, input power fail, thermal warning, and enable and inhibit inputs. An optional I2C serial data output monitors output voltages, output currents, internal temperature and cooling fan speeds for interfacing with a host system.
