Hotraco Motor Control Units

With the GMC-1, the GMC-2 and the GMC-3, we are introducing the first products from our new range of motor controls. The GMC series distinguishes itself from Hotraco’s previous relay boxes/power units by the fact that the thermic safety has become surplus to requirements. In other words, a single version for the entire range of currents! These products are also characterised by universal operation and structure.

The GMC is a motor control for controlling 1-phase or 3-phase motors that, for example, open and close windows and also for hoisting motors. The GMC can be operated both manually and automatically.

Hotraco GMC-3 Implementation

The GMC can be supplied in a version for 1, 2 or 3 motors, with a maximum motor current of 6.0A per motor. The motor current is measured in 2-phase and is adjustable by means of a potentiometer and to read out with the MCSD service display. The GMC is supplied as standard with a lockable work switch, manual operation using push buttons and current measurement per motor.

The computer control is 24 V AC/DC, and the GMC is available in 1-phase 230 V and 3-phase 230 V or 400 V versions. Other voltages are available on request.
