The CV21GE (Analog) are combination test benches for 6, 12 and 24 Volt starter motors and alternators. The drive motor is PLC controlled and has a capacity of 7.5 kW. This makes it possible to test alternators to a capacity of 200 amperes and 240 amperes at 24 Volts. To test maximum capacities, the CV21GE is fitted with resistors to a capacity of 4800 Watts. The motor is driven at two fixed rpm (1500 or 3000 rpm), or fitted with a variable regulator.
