UNIPOWER's TPCMQ24 series DC/DC bus converters convert 24VDC to either 48 or 54.4VDC for a variety of applications including industrial and telecommunications. Output current is 20.8A at 48V or 18.4A at 54.4V, giving 1000W of total power. These converters operate from a wide range 20 to 30VDC (24V nominal) input with an efficiency of 89% and power density of 12.5W/in³.

The hot-swap TPCMQ24 converters are only 1U high and are rack mounted in a 19-inch shelf that can accept up to three converters for 3000W of total power. The output from the shelf is 62.4A at 48V or 55.2A at 54.4V. For added power, multiple shelves can be paralleled and the system can also be used in N+1 redundant mode.

Other features of the TPCMQ24 converters include automatic load sharing, output ORing diodes, adjustable output voltages, a 5V, 250mA standby output, integral LED status indicators, and control and monitoring features which include output power good, input power fail, thermal warning and inhibit functions.

The TPCMQ24 DC/DC converter modules and shelves must be ordered separately. Delivery is stock to 4 weeks ARO.
