Digital Multifunction Controller
What's
ESK100 device is a multifunction digital unit with 2+1 transducer inputs, to regulate the speed of single-phase AC Motors used in axial or centrifugal fans. Designed using a "state of art" microcontroller, is suited to have a choice of 14 different default software configurations ready for ventilated heat exchanger applications. It is optimized with “IES”, the innovative control algorithm for HVAC&R applications. The ALL-IN-ONE controller, is completed with : the inside protection against the short circuits with a Protistor “FUSE”, the Power switch, the direct connection of n. 6 + 1 single phase fans (on request), the THD system (on request), to be in compliance with EN61000-3 & 3-12 (about the Total Harmonic Distorsion). Using a serial Modbus line option on request) it’s possible to read & write all the parameters of the device, testing and controlling also from remote sites the state of the machine. A Selpro software called Clima-Sinergy is already allowable. Clima-Sinergy allows data collection, analysis with graphs, change of working parameters, optimization of performances through the comparison between two ventilating groups
