YUDO Temperature Controller
operates with supply voltage 220~240V AC.
But even in case of supply voltage 380~415V AC 3phase 4 line, by re-wiring as shown
below, 220~240V AC can be taken between one phase(R, S or T) and Neutral(N).
YUDO Temperature Controller be supplied with wiring for supply voltage 220~240V AC
unless special instruction. Please check the current wiring.
