EA900103 – EEDS 3A Switched with Tk – Flakt Woods

The electronic speed controllers of the EEDS series control the speed of single phase voltage controllable motors (230 VAC, 50/60 Hz) by varying the supplied voltage. The controller has connections for motors equipped with thermostat (Tk) overheat protection (NC-contact). When overheating is detected power to the motor is stopped. The red indicator light and alarm output will signal this error condition (reset: main switch to off position and back). The working principle of this product series is based on zero crossing detection. An optotriac combined with a microprocessor ensures flawless and accurate control. OC (open contact – normal mode) and CC (closed contact – normal mode) inputs are provided for remote starting and stopping via thermostats, PIR and/or frost protection, etc. There is a potentiometer and a separate on/off switch with built-in illumination. The erminal board has a supplementary connection to branch off non-controlled 230 V. A safety isolator/switch disconnector should be installed on the mains side of all motor drives; refer to SISO.
