The ST400S-C1F-V2+1A power measurement and control instrument uses AC sampling technology and has high-precision measurement functions for voltage, current, power, and electrical energy; Supports multiple standard fieldbus communication interfaces and can achieve the "four remote" function; Cooperating with circuit breakers for low-voltage incoming and feeder circuits, remote operation monitoring and management of electrical equipment can be achieved; The selection of "control modes" such as frame circuit breakers, molded case circuit breakers, and general control can be achieved through programming; Various measurement parameters and status can be displayed and queried through the LCD display module.

The ST400S-C1F-V2+1A power measurement and control instrument is equipped with auxiliary protection functions such as grounding tripping, undervoltage alarm/tripping, PT disconnection alarm, overcurrent alarm, etc., to improve the protection functions of incoming and feeder circuits. In addition, the ST400M/H series is also equipped with auxiliary control circuit disconnection alarm function.

 

Product Features

The product adopts a modular and split structure, with a small volume, and can be directly installed and used in a 1/4 module drawer cabinet.

The product has measurement functions for electrical parameters such as current, voltage, frequency, active power, reactive power, apparent power, power factor, active energy, reactive energy, etc. It also has 4-20mA analog output function.

The ST400III series has 9 switch inputs (dry contacts) and 4 relay outputs; The ST400M/H series has 8 switch inputs (wet contacts) and 4 relay outputs.

The product supports multiple standard fieldbus communication interfaces such as Modbus RTU, Profibus DP, and dual Modbus RTU;

The set parameters and energy data have power-off memory function;

Real time display of fault and alarm interfaces through the display module (where ST400MH is also equipped with clock function).
