Scr torque derate.

The effective impedance of any device will vary with temperature. If that impedance rises with temperature, two devices in parallel will share reasonably well. The device carrying more current heats up more, and its fraction of the total current drops. But if the impedance of the device drops as temperature rises, the device carrying more ...International 2019 with Cummins engine. Truck came with SCR code for DEF lines.
