300Vdc Input, 2.5kW DC/DC convertes target rugged industrial applications

High DC-input voltage, wide DC-input range

AC-input versions available

The HBC 2K5-3U3 Series industrial quality DC/DC converters deliver up to 2.5kW output power. They operate from a nominal input of 300Vdc (270-350Vdc range). Other DC-inputs requirements can be readily be accommodated. Versions of this design with 230Vac or 115Vac inputs are also available.

The series provides standard output voltages of 24V/100A, 28V/90A, 48V/52A, 56V/45A, 110V/23A, 125V/20A or 250V/10A, with other outputs available on request. The output is isolated, floating and can be grounded to either terminal, so that the unit can be used in either positive or negative grounded systems, or left floating.

The HBC 2K5-3U3 is built with three rugged HBH 65 internal modules. A built-in output redundancy diode separates the internal modules and also allows for a number of units to be connected in parallel to achieve higher output power or additional redundancy. The output redundancy diode also makes the unit suitable for battery charging applications.

The converters have generous design headroom and are rated for operation over a 0°C to +50°C temperature range without de-rating; wider temperature ranges are available. Cooling is by high quality built-in fans. They are ruggedized and all printed circuits are conformal coated, which provide immunity to shock, vibration (IEC 61373 Categories 1 A&B) and moisture. Heavy ruggedizing is available for operation in extreme environments.

The HBC 2K5-3U3 Series complies with EN/UL 60950-1 and equivalent industrial safety standards. The input and output are filtered for low noise. Efficiency is 80% (minimum) at full load, depending on the input/output configuration. Protection features include 4300Vdc input/output isolation, overload, over-voltage and short circuit protection with thermal shutdown and automatic reset. Module fail alarm (Form C) and remote shutdown are available as options.
