Digital motor relays for protection and control
A comprehensive range of digital protection relays to protect motors from abnormal conditions in the power supply, faults in the cable and problems in the motor itself is now available from Softstart UK. Manufactured by Solcon Industries, the range includes models to cover all requirements from monitoring abnormal temperature conditions alone to providing full protection from all possible faults with the addition of advanced control capabilities for all types of starting methods. Affording the highest levels of motor protection, the MPS 3000 and MPR 2000 are ideal for high voltage motors, large low voltage motors and applications where full protection and advanced warning is crucial.
Both digital motor protection relays monitor three phase currents, ground currents, voltages and up to ten temperature inputs, with the MPS 3000 offering multiple levels for each protection function.
For both models, each protection function can be designated as an alarm fail-safe, a trip (or trip fail-safe), an auto reset, a panel reset or a remote reset.
Within the 3000 and 2000 ranges are models that offer advanced motor control functions in addition to motor protection.
These cover all types of starting methods, including soft starters and variable frequency drives.
For example, the MPS 3000/C provides 16 discrete inputs to enable full control of motor start, stop, rotation direction change, etc Where such high levels of functionality are not required, the MPR 6/3 DGF is a new generation of microprocessor based relay designed to protect three phase induction motors.
With its full array of motor protection functions, the addition of direction ground fault function and three thermal sensor inputs, the MPR 6/3 DGF provides a comprehensive protection package.
In the same family as the MPR 6/3 DGF, the TPR 6 provides comprehensive protection from abnormal thermal conditions.
Monitoring up to 14 temperature inputs, the TPR 6 accurately creates a thermal model to protect the motor from faults such as abnormal heat in the windings or bearings.
Each protection function can be designated as alarm only, trip only, combined alarm and trip, disabled, enabling auto reset, or a programmable output.
Serving the UK and Republic of Ireland as the exclusive agent for Solcon, Softstart UK is dedicated to the supply of solutions to the starting, protection and control of AC motors, offering a vast wealth of experience in the planning, development and application of all motor starting solutions.
