Frequency inverter with integrated sine filter for three-phase motors Universal control unit for clean room, refrigeration and air conditioning technology Frequency converter with multifunction display with plain text display for constant temperatures or constant pressure in pipe systems including integrated process controller (PID freely programmable) or 0...10 V control signal. The setting of two setpoints or manual operation is possible. The unit has 2 digital inputs, 2 analogue inputs, an analogue output with 0...10 V and 2 relays with change-over contact. All of these inputs and outputs are programmable. Protection of the motor is ensured by connecting thermal contacts or PTC thermistors. Pre-programmable operating modes make the frequency inverter easy to configure. English, German and Swedish can be selected as menu languages. The power supply for sensors is +24 V (Imax 120 mA). Blanking of up to 3 speed ranges is possible, with minimum and maximum speed limitation. Parallel operation of all fans is possible without damaging the motors. Shielded motor cables are not required!
