The DSP-1L or DSP-1LM is used to protect your three-phase motors against loss, imbalance or inversion. It continuously monitors each phase of your power supply. In case of phase loss, imbalance or inversion, the DSP-1L cuts off the power to the control circuit and thus protects the motor concerned.
The DSP-1LM is used to transmit a signal to a PLC. As soon as the three-phase power supply returns to normal, the DSP-1L enables the engine to restart normally and safely. However, the DSP-1LM’s Optomosfet contact will trip again.
Would you dare to connect your electrical equipment to a power supply not protected by fuses or circuit breakers? So now that
you know about the DSP-1L and DSP-1LM detectors, you know how to protect the production of your business against phase failures.
