Able to control BOTH fixed speed and variable speed compressors?

Yes

Product incorporates anti-tampering mechanism?

Yes

Product incorporates microprocessor that can detect/determine efficiency to load level curve for variables speed compressors?

Yes

Does the product incorporate a pressure transducer that has a measurement accuracy <= +/- 0.5% of full scale across its rated operating pressure range and across a rated temperature range of -25 to 80°C?

Yes

Does the product incorporate automatic control algorithms that monitor rate of change in system air pressure/flow and prevent compressors from being brought on load or unloaded in response to small fluctuations in demand?

Yes

Is the product capable of automatically regulating the operating pressure of the compressed air system, based on the output of a single pressure transducer, to within +/- 0.2 bar of the operating pressure set-point, as air demand varies between 10% and 100% of the maximum combined, continuous, rated output of air compressors being controlled?

Yes

The product is able to control

At least two air compressors

Does the product conform with the requirements of The Electromagnetic Compatibility Regulations 2016, and have an appropriate Conformity Assessment mark?

Yes

Uniclass codes
