Electric regulators

DESCRIPTION

Manual voltage controllers with continuous adjustment by potentiometer. Electronic control with closed-loop triac phase control. Suitable for adjustable single-phase asynchronous motors.

Note all triac controllers can make the motor hum at low speeds. We do not recommend reducing the rated speed of an electric motor by more than 50%.

These models are adjusted with a rotary potentiometer with switch.
A dedicated built-in trimmer sets the minimum as the starting point of the control range.

Made with a radio-interference filter, in accordance with current regulations.

DESCRIPTION

The EM5 is a new-generation electronic speed controller designed for use with universal asynchronous single-phase and three-phase motors and brushed motors.
The EM5 uses intelligent control that is efficient especially at low speeds, together with simple operation, because the initial boost is guaranteed in every case. After the start-up phase, the speed returns automatically to the one set by the user.

ADVANTAGES

A THREE-PHASE motor can be supplied from a SINGLE-PHASE supply using a capacitor.
The EM5 software ALWAYS guarantees that the motor starts; after this start-up phase, the motor speed is set to the point the user has chosen.
The EM5 software, which can be customised on the product, then optimises operating efficiency and the control function.
The EM5 protects the motor from overheating by means of a thermal image.
Low-speed control with the EM5 considerably improves motor efficiency compared with normal triac control.
