TwisTorr Medium-TMP onboard Controller

The Medium-TMP onboard controller is a solid-state frequency converter driven by a single chip microcomputer. It consists of a PCB including power supply, three-phase output, analog input/output section, microprocessor, and digital interface section. The power supply, together with the three-phase output, converts the single-phase AC mains supply into a three-phase, low voltage, medium frequency output required to power the pump. A remote host computer can operate the controller via the serial connection. Optional Windows-based A-plus software is also available. The Medium-TMP onboard controller can be mounted onboard, on the bottom or using an optional bracket on the side, of the TwisTorr 704 FS and 804 FS pumps.
