The differences in Regulation/Transmission types:
Explanation of the Regulation/Transmission type:
- Five step (0 – 25 – 50 – 75 – 100%) => used for 5 step Piston compressors (not for screw compressors)
- Load/Unload/Modulation (0 – 100%) => For a fix speed compressor
- Three Step (0 – 50 – 100%) => used for 3 step Piston compressors (not for screw compressors)
- Variable Output (0 … 100%) => For a VSD compressor
Additional information for "Power and motor data":
Explanation “Power and motor data”:
(These values can be found on the datasheet of the compressors and some on the nameplate of the compressor)
- Power supply voltage. => Is the machine incoming voltage.
- Power factor => Power factor is the ratio between the kW and the kVA drawn by an electrical load where the kW is the actual load power and the kVA is the apparent load power. Simply, it is a measure of how efficiently the load current is being converted into useful work output and more particularly is a good indicator of the effect of the load current on the efficiency of the supply system.
- Power factor Loaded => Power factor of the compressor in Loaded condition
- Power factor offload => Power factor of the compressor on offload condition
- Total package power loaded => this is the complete input power requirement, in kW, of the compressor package when the compressor is running at the Full Load Operating Pressure. (machine rated value)
- Total package power offload => this is the power consumed by the compressor with its lowest pressure required. (machine rated value)
- Nominal motor power => The nominal motor power is the measure of how efficiently a compressor package produces compressed air. (= motor rated power)
- Frequency => Frequency that compressor works.
