| ¡¡¡¡ Principles:The
YDB multifunctional electric motor protector can detect the
signals of current and voltage.while failures,including lack
of phase,overloading,short circuit,leakage,occur,they will be
identified and sampled via respective testing circuit,and then
be transfered to output control circuit after being analyzed
and processed.And the power supply will be cut off and the cause
of failures will be indicated.
¡¡¡¡Expanding:"The
YDB multifunctional electric motor protector" is highly
honored and listed as one of the main expanding electromechanical
products throughout the country by national authoritative
department.
