| | | Description Delta Drive Micro from motron is a miniature plug and play LOW COST frequency converter, intended for variable speed regulation of fans etc up to 370W max with a 2-10V input range and apr. 5-50Hz output range with linear V/F control. 0V on control line will stop the motor. Delta Drive Micro is an extremely robust product in a Die Cast Aluminium box which can be placed almost anywhere. It is simple to use, and yet very efficient in control. The electronics has been sealed with resin for maximum robustness and user connections are avaliable throgh terminals inside the cabinet. Delta Drive Micro will connect to 230VAC powersupply, a standard 230V AC motor and a simple 2-10V isolated control signal will command the motor to run at specified speed. Delta Drive Micro has an input detector, which will STOP the motor, if the inputsignal is less than apr. lV=, so no need for an extra start/stop signal, its all been taken care off. Delta Drive Micro has a number of build in safety funtions, which all will stop the motor, and retry after apr. 30 seconds. Overtemperature, motor shorts, overvoltage, undervoltage, ground failures etc will be detected and stop the motor. Delta Drive Micro comes in different versions. Mainly, a Wall Mount version with integrated bottom flanges for mounting. Also, a Flange Version is supplied for mounting directly in some kind of Air Convection systems. This type needs to be cooled by forced air , as in Chimneys etc. Delta Drive Micro is designed with an integrated Emc filter to comply with International regulations. Isolation between control input and live supply is designed to withstand min 3kV, according to the LVD directive. CE Pending Delta Drive Micro is as standard supplied with glands and snap in terminals for connections, but an alternative is a Complete Delta Drive with integrated Cables as per Customer requirements.

| | | Connection | | Trimmer inside Maximum speed can be adjusted from the integrated trim potentiometer. Maximum frequency, 50-60 Hz, can be adjusted between apr. 5-10V of the input control voltage. So, Max speed can be achieved with 5V DC systems as well as with 10V DC systems. Automatic stop as well. Speed should be limited at 50 Hz for standard Motors. No Slip in motors can be tolerated, as the current will increase in a progressive way. Stopping of the FC 370 will always take place when the dc input signal is less than apr. 1-2V. As it is a "low cost" frequency industrial converter, and the input signal comes from an optocoupler, there there can be slight deviations from units to units. | | |
