TVSS5

TVSS5 electronic three phase fan speed controller The TVSS5 automatically controls the speed of three phase (3 x 400 VAC/50 Hz) voltage controllable electric motors with a 0-10 VDC or 0-20 mA control signal. This makes it possible to control these motors automatically with an external PD-controller, remote with a potentiometer or a microprocessor with analog output. There is also a connection for a remote start/stop switch. The working principle of this product series is based on the so-called zero crossing detection. An optotriac combined with a microprocessor ensures flawless and accurate control. There are two working modes, internally selectable by switch. With kickstart the motor will always start or restart at max. speed for 10 seconds, after which it will automatically follow the position set by the 0-10 VDC or 0-20 mA control signal. Without kickstart the motor starts according to the position set by the 0-10 VDC or 0-20 mA control signal. The CNVT-PWM-010V can be connected to provide a conversion of a PWM signal to a 0-10 V signal.
