Controller

The controller is equipped with complete relay protection and programmable logic, supports various standard communication protocols and remote communication, accurately measures electrical parameters, flexibly configures reclosing settings, and provides large-capacity event recording. It supports customized expansion to fully meet the intelligent control requirements of distribution automation.

Core Advantages

• With vacuum interrupter and permanent magnetic actuator, the switching operation is precise and stable, with mechanical life up to 30,000 operations, long maintenance-free period, suitable for long-term unattended outdoor operation.

• It supports multiple operation modes including independent phase control and three-phase linkage, featuring single-phase tripping, single-phase reclosing and single-phase lockout, which can accurately handle single-phase grounding and phase-to-phase faults, greatly reducing power outages in non-fault areas.

• It integrates a full set of protection logic such as overcurrent, instantaneous overcurrent, zero-sequence, directional, over-voltage and under-voltage protection, supporting 10 ANSI/IEC protection curves to flexibly adapt to various line protection schemes.

• Standard with RS485, Modbus, DNP3.0, IEC 60870-5-101/104 protocols, supporting GPRS/GSM remote communication, it can be connected to distribution automation systems for remote monitoring, fault recording and event logging.

• The whole unit adopts 304 stainless steel tank with IP54 protection, resistant to high and low temperatures, corrosion and vibration. It can operate stably for a long time in extreme environments from -45℃ to +85℃, adapting to plateaus, coastal areas, cold and hot climates.

• Flexible installation including single-pole, double-pole mounting and substation installation, with standard interfaces and cable configuration for easy on-site wiring and commissioning, suitable for both renovation and new projects.
