I5kM based on rated capacity 20 wA. 25 Wh, 30 kVA, nine types. The altitude applicable for dimmer calibration is divided into A and B Three types of C, among which: - A type: altitude 2 000 ■ and below:_- Type B: Altitude of 3000 meters and below:_- Type C: Altitude 5000 meters and below. Dimmers are divided into two types based on output characteristics: chopper type dimmers and sine wave type dimmers
