Power resistors - Import export

In connection with very precise digital voltmeters the model 1282 resistors are used as measuring resistors for accurate registration of direct and alternating currents up to 200 A. The compact construction supports universal application. The exceptional low temperature coefficient extends the scope of application a second time. A typical application is the wide range of quality and reliability testing. Regular measurements give a reliable information of the quality level of parts, instruments and systems. Technologies already approved with our precision and calibration resistors - which especially guarantee a secure conduction of the dissipation heat - have been transferred to the precision high capacity resistors. Features: — Temperature coefficient ≤ 10 ppm/K — Nominal load 20 W — Ranges 1 mΩ ... 100 mΩ — Four-terminal measurement principle — Accuracy 0.02 % — For technical frequency 50 Hz

"The demand for speed control has taken off with the advent of IGBTs and powerful microprocessors. Today, there is no longer any difference between DC and AC. 99% of new installations will be equipped with variable speed AC solutions. In our product range, we have both DC and static frequency inverters. Characteristics of a static frequency inverter: OPEN LOOP CONTROL - Single and three-phase power supply between 200 and 480V - Digital inverter - Solution only in 1 or 2Q - Possible braking via chopper and resistor - Power between 0,37kW and 22kW - IP20 protection - Modular drive - We have a stock up to 22kW in single and three phase CLOSED LOOP REGULATION - Single and three-phase power supply between 200 and 500V -Digital dimmer -Solution only in 1 or 2Q -Braking possible via chopper and resistor -Power between 1,3kW and 900kW -IP00/IP20/IP54 protection -Modular drive We have a stock up to 160kW in three-phase 400V"
