TOSUNLUX (Tosun) · 4 → 12 outputs
JKW5C var relay, an automatic reactive power compensation controller for low-voltage capacitor banks: it continuously measures cos φ, voltage, current and reactive power, then switches the capacitor steps in or out (4, 6, 8, 10 or 12 outputs) to hold the power factor. Automatic or manual mode, LED display.
