![]() ![]() ![]() All heat generating components are installed on aluminum heatsink blocks which are thermally connected to the base plate. Additional cooling is achieved by natural convection through the cooling slots. ![]() The HVT 350-F7 converters are cooled by conduction via baseplate. 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.Ħ00W, High DC-input voltage (1100Vdc) and wide operating input ranges (750-1400Vdc) with fan cooling. The input meets EN55032 Class A with wide margins. The input and output are filtered for low noise. 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. Other electronic protection includes inrush current limiting, reverse polarity protection, output current limiting, short-circuit protection and self-resetting thermal shut-down in the case of insufficient airflow. The design is verified for 5600Vdc input to output isolation and production level testing is 4300Vdc input to output. To ensure high reliability and long operating life, all critical components on the primary side are designed and tested for corona inception levels that are significantly higher than the operating voltages. We also offer a number of other ultra-high input voltage designs including a 200W, 600W, 1000W and 2400W version. The output separation diode also makes the units suitable for battery charging applications. An output-fail alarm (Form C) and remote shutdown or enable are available on request. The 350W units deliver a single output of 24Vdc, 36Vdc, 48Vdc, 110Vdc, 125Vdc or custom.Īn optional built-in redundancy diode allows for a number of units to be connected in parallel to achieve higher output power or N+1 redundancy. The converters accept a nominal input voltage of 1100Vdc and offer a wide operating input voltage range of 900Vdc to 1300Vdc, with 1400Vdc peak voltage. The HVT 350-F7 series of rugged of DC-DC converters are designed for heavy-duty industrial applications that require an ultra-high DC-input voltage and wide DC-input ranges. 350W Conduction/convection cooled DC-DC converters with high DC-input voltage (1100Vdc) and wide DC operating input ranges (900-1300Vdc operating range, 1400Vdc peak). ![]()
