Sep 18, 2018

Integrated protection and control functions.

Three-phase full-charge measurement, three-phase voltage, current, power factor, active power, reactive power, apparent power, active energy, reactive energy and other measurement values can be displayed in the local LCD panel, can also be transferred far to the monitoring system.

With direct start, two-way start, star/triangular start, self-coupling transformer start-up and other start-up control mode, with the electric self-starting function, can realize the motor batch restart. Equipped with a small dedicated core-type current transformer (less than 160A), for small-power motor can eliminate the external current transformer, save costs. One-way switching input monitoring, with 64 SOE event logging capabilities, including time and type, event logging can be uploaded to facilitate failure analysis of event causes (the number of event records can be expanded).

Up to 5-way relay Intelligent control output, to achieve protection trip output, alarm output, control output and other remote functions.

With short-circuit protection, blocking protection, fixed-time overload protection, grounding leakage protection, three-phase current imbalance protection, phase-out protection, undervoltage protection, overvoltage protection, start-up time over-length protection, process chain trip and apply proof-type motor te time protection, to ensure safe and reliable motor operation. Provide 4~20ma analog output/analog input function to meet the needs of users.
