Digital Electric Protection

Microprocessor protection system EZAD – M1

Microprocessor protection system EZAD – M1

EZAD-M1 is a digital device for protection and work mode control of AC motors 380 V from the whole variety of powers – 0,5 – 300 kW in the electric drives of pumps ventilators, centrifuges, transport conveyors etc. that work during long or short periods of time. EZAD-M1 realizes an exact thermal model during heating and cooling of the electric motors, which is based on standardized thermal limit curves. There is an LCD display a powerful PIC processor with an in-built ADC and standard interface RS 232 allowing connection to other processing devices.

Digital Electric Protection

Microprocessor short circuit protection system EZAD-MT

Microprocessor short circuit protection system EZAD-MT

EZAD-MT is a digital device for short circuit protection of the start-up equipment in the electric drives of AC motors 6kV. When any of the predetermined values for the motor current is exceeded, the device turns off the motor with 50 ms time delay. When the device is activated the values of the three linear currents are memorized thus making it easier for the servicing personnel to localize the malfunction. When the EZAD-MT is working it indicates the three linear currents thus providing motor’s loading visualization. For the full protection it is referred to use the EZAD-MT in combination with the base protection module EZAD-M1.
