Features superior harmonic noise characteristics and can be used
for a wide frequency range (30 to 200 Hz), allowing application in
the secondary coil of the inverter control circuit.
(For instantaneous, 50/60 Hz only).
˙A warning alert is activated during overload to prevent a system failure due to a sudden over-current trip.
˙A bar graph on the display monitor during operation enables constant monitoring of load status, allowing easy maintenance.
Total cumulative motor run time is displayed for convenient
scheduling of maintenance and repair.

Real-time current for each phase of the three-phase current is displayed continuously in sequence to allow constant monitoring of
current values.
˙Up to ten of the most recent failure events, up to 50 system events are stored (Advanced Type - Comm. Type)
˙Up to the five latest events of failure and three-phase current values at the time can be checked on the indicator.
˙A fault current waveform of the latest trip is stored to assist in diagnosis of the cause of the event. (Advanced Type - Comm. Type)
˙ Current waveform of the motor in operation can be easily viewed without the need of separate Current measuring equipment
(Advanced Type - Comm. Type)
