Key Features
Product Overview
JKWF series phase‑separated automatic reactive power compensation controller adopts high‑performance microprocessor as the core component. It samples three‑phase voltage and three‑phase current signals, with a maximum of 16 output loops. It supports full phase‑separated compensation, full common compensation, and combined common‑and‑phase‑separated compensation modes. Meanwhile, it provides 12 capacitor combination modes (capacity coding), which can be selected by users via modifying control parameters, and the settings are permanently saved after modification. It controls the switching of capacitor banks by combining fundamental power factor and fundamental reactive power, featuring stable switching without oscillation and low harmonic sensitivity. It can accurately display power data and perform switching control, and is applicable to automatic reactive power compensation control for 0.4 kV systems.
