HV-AN 1u-250 ISO 21498

The HV-AN 1u-250 ISO21498 is an artificial network used to simulate the impedance of an electric vehicle during emission measurements.

The impedance characteristics are according to ISO 21498-2 and can also be used for MBN 11123 and BMW GS95023. It is used to test small to medium power HV components i.e. DC-DC converters, On-board chargers OBCs, small e-motor inverters, etc.

Specs:

Sold as a set of two HV-AN 1u-250-xx (one each used for the HV+ and HV- supply lines)
The “250” is available with 10, 25, and 100mOhm resistance
The max current is not always 250A but depends on the resistance value

SMT

For more than 20 years SMT is the designated specialist for thermal processes with more than 5000 sold units. Know-how easily could be purchased at SMT.

Progress, innovative technology that takes the preservation and protection of resources and the environment into consideration is the philosophy of SMT. Not without reason is SMT the manufacturer of the most energy-saving and easiest to maintain reflow soldering systems in Germany, systems where heat transfer is effected exclusively via a positively-driven convection system.

The portfolio consist from extremely small systems for laboratories and development, via medium-sized units and on down to large systems for the industrial production of electronic modules. Customer-related wishes are always taken into consideration and so flow into our company as part of the continuous improvement process.
