| | | Description The MOTRON Motor Control 7 is a totally encapsulated and very robust TRIAC controller with 7A output and 100% galvanic isolated controlinputs. It is meant to be mounted on an Capacitor motor .designed for Triac control, and can be attached next to the capacitor, close to the motor. MMC 7 has all electronic build into the "tube", totally integrated and thereby robust to water, temperature,humidity,mechanical stresses and many other factors. No liquid can reach the electronics, making the MMC 7 unique among isolated triac controllers. And yet simple to use. MMC 7 is supplied and controlled from the same multicable, making it an easy task to connect to an Ac motors connection house. Delivered with 1m of cable with numbered leads from 1 to 10, and an yellow PE wire as well. The tube is of aluminium, and PE is connected to the case inside !. MMC 7 is a new way of controlling motors with the traditional Triac Principle, but is controlled from an micro, guaranteed zero DC level, no spurious trigger and an sophisticated "closed loop" control, that constantly measures the voltage output, compares it to the input and corrects the output from the error. This pseudo "closed loop" in fact does mean that the motor is at the aprx. same speed for almost any loads. Which can be tricky for an AC Capacitor motor. MMC 7 has an totally galvanic isolation between power and control, making interfacing to low voltage external controllers no problem. Ask MOTRON for an appropriate controller, ie the Coolman 6 which can be configured to temperature,humidity,pressure,voltage or almost anything that needs to control the speed of an AC motor. There is an START input, which when taken low activates an internal relay and connect the L1 phase to the output. This makes the MMC 7 even smarter, because no external contactors/relays is needed for stopping and starting the AC motor. MMC 7 is protected against overtemperature, an build in switch will OPEN when temperature reach around 80°C inside, making the external controller take some action ! MMC 7 has an auxilary 10V DC output, which can be used for potentiometers, sensors, controllers etc. not exceeding 50mA MMC 7 can automatically start/stop the motor from the internal L1 relay upon limits from the Dc control input. This is an feature that diverts from each application, please ask MOTRON A/S._ | | Picture | | |
