Emergency Braking Systems for all types of machinery including radial drillers
QS10 units are suitable for dual wound, D.O.L. motors.
Supply Voltage:
- From 240 volts single phase to 415 volts 3 phase 50 Hz.
Standard Models:
- QS2: For motors up to 3 h.p. (2.2kW) D.O.L. 3 phase or up to 0.75 h.p. (0.55kW) single phase.
- QS5: For motors up to 7.5 h.p. D.O.L. 3 phase or up to 1 h.p. single phase.
- QS10: For motors up to 10 h.p. (7.5kW) D.O.L. 3 phase or up to 2 h.p. (1.5kW) single phase.
The Quickstop DC injection braking unit provides a rapid or controlled stop every time the tripping device is activated. This could be a trip switch, stop button or any device which opens its contact when operated.
The device works by cutting the A.C. supply to the electric motor and then injecting D.C. into the motor windings. This causes a magnetic field in the stator that causes the rotor in the motor to stop.
Our range comprises of two types - a transformer rectifier type and/or an electronic device style.
For rapid stop that is required for a radial drill - the transformer rectifier type is recommended because it has a quicker response time. For most other applications - the electronic units are normally suitable.
