Converters target power systems that transmit high voltage, high power over long distances.

HVI-3K-1300-24-4U5 high-input voltage connectors

The HVT 2K5-1300/24-4U5 is a high input voltage, industrial quality dc-dc power converter designed for driving low voltage 24Vdc equipment. The converter is typically designed into power systems that transmit high voltage and high power over long distances.

The unit converts high voltage direct current in a 1000Vdc to 1500Vdc range, to 24Vdc/100A. The output can be customized for 48Vdc, 110Vdc and other output voltages. Input to output safety isolation is 5000Vdc and input to chassis isolation is 3450Vdc. Conversion efficiency is typically 85% at 1300Vdc nominal input, at full load.

The HVT-2K5-1300/24-4U5 converter is built with rugged internal modules connected parallel via internal redundancy diodes. This modular construction provides inherent redundancy and ensures that the unit remains operational even if one of the internal modules fails. The built-in redundancy diodes also allow several units to be connected parallel for output power at 5kW, 7.5kW and higher. The low voltage output can also be connected in series to generate higher voltage, or multiple outputs.

The HVT-2K5-1300/24-4U5 is cooled by high quality built-in fans that ensure operation over a 0°C to +50°C temperature range for full specification with no requirement for derating. Wider temperature ranges are available on request. The 177 x 305 x 419 mm chassis is ruggedly constructed and is designed to withstand high levels of shock and vibration to IEC 61373 Cat 1 A&B. Conformal coating provides protection against humidity and airborne contaminants.

The input and output on this converter are filtered for low noise. The input meets the requirements for EN55022 Class A with wide margins. Class B is available on request. This ensures that the unit can be used in EMI sensitive environments without additional filtering. Electronic protection includes inrush current limiting, reverse polarity protection, output current limiting and short-circuit protection. The unit is designed for compliance with IEC61010-1, UL508C and equivalent safety standards. Low component count, large design headroom, and the exclusive use of components with established reliability also contribute to ensuring that the unit delivers many years of problem free operation.
