DC/DC converters deliver up to 2,000W

The HVI 2K-F6W units operate between 700VDC to 900VDC input range, 800VDC nominal input. Regulated output voltage includes 24VDC, 28VDC, 36VDC, 48VDC, 110V or custom. An optional built-in redundancy diode allows for parallel and N+1 operation, or back-up battery connection. An output-fail alarm (Form C) and remote shutdown or enable are available on request. Efficiency is a minimum of 80% at full load depending on input/output configuration.

The units are filtered on the input and output for low noise. The input meets EN 55032 Class A with wide margins (Class B option). This ensures that the unit can be used in EMI sensitive environments without additional filtering. The converters comply with the requirements of EN/IEC 61010-1 and related standards.

The HVI 2K-F6W design is verified for 5,600VDC input to output isolation and production level testing is 4,300VDC input to output. The units are equipped with reverse polarity protection, inrush current limiting, output current limiting, short-circuit protection and self-resetting thermal shut-down in the case of insufficient airflow. 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 trouble free operation.

Cooling is by high quality built-in fans with additional cooling provided by conduction via the baseplate. This ensures operation over a 0°C to +50°C temperature range for full specification without the need for derating. Wider temperature ranges are available on request.

Heavy ruggediSing ensures immunity to shock and vibration (IEC 61373 Cat 1 A&B), which makes the units suitable for operation in extreme environments. The internal boards are conformal coated for protection from moisture, humidity and airborne contaminants. The units measure 254x65x349mm.
