In September 2017, the new product GLS350 power factor controller was released.

GLS350 is a flexible modular intelligent reactive power automatic compensation control system, which consists of two basic components: basic unit and extended module. The basic unit as the main components, mainly completes the data acquisition, communication, logic control function is the core of the whole system, and expansion module or intelligent switch connection through the communication interface, the communication way of collecting extended input signal module, intelligent control switch points. This architecture optimizes the control between various switching switches and capacitor banks, greatly improves the flexibility of various reactive compensation schemes, and greatly reduces the cost of switching, running and maintenance of reactive power compensation systems. The basic unit and the expansion module are connected in RS485 mode, which supports 32 groups of capacitor switching.
