• CE, cUL (UL and CSA up to 600V). EL-FI Shaft Power Monitors. The EL-FI M20 supervises induction motor driven equipment and provides alarms when abnormal loads are detected. The EL-FI M20's ability to provide reliable monitoring and protection ensures production equipment is optimised and expensive breakdowns and interruptions are minimised. Due to the special method of subtracting motor power losses, the monitor is able to accurately measure the shaft power supplied by the motor to the application. This advanced technique allows the EL-FI M20 to monitor the application load only as opposed to the total motor load, which includes varying motor losses.,Typical applications include monitoring pumps: centrifugal, impeller, screw, magnetically driven, submersible, lobe motor, peristaltic and membrane types. Also suitable for monitoring tool failure on machine tools, mixer protection, jamming material of free-running conveyors, automatic doors, blocked screw feeds,etc. For motors up to 999A 100-690Vac (single ; three phase) The motor is used as the sensor Unique algorithm for calculating motor power losses One Touch Auto Set (hassle-free commissioning) Four alarm levels: Max and Min Main Alarm; Max and Min Pre-Alarm Analogue output with P-span/scaling (0-20, 4-20, 20-0 or 20-4mA) Digital input for external Auto Set, Reset or Blocking Alarm Fully programmable with LCD screen Readout in true figures i.e. 5kW, Amps etc Compact size - 90 x 45 x 115mm Easy 35mm DIN rail mounting IP20
