Dehumidifier with single and three=phase AC supply connections - has separate sets of contacts and internal wiring to switch serving two identical motor-blower drying units via relays

The dehumidifier incorporates two air-dryers (20A,20B) each having a series AC motor (22), a heater (24), a blower (26), a temperature sensor (28), and a hygrometer (30) with a bypass switch. One set of contacts (12) is provided with three phase lines (L1-L3) and a neutral line (N1). Three other set...

Beschreibung
Zusammenfassung:	The dehumidifier incorporates two air-dryers (20A,20B) each having a series AC motor (22), a heater (24), a blower (26), a temperature sensor (28), and a hygrometer (30) with a bypass switch. One set of contacts (12) is provided with three phase lines (L1-L3) and a neutral line (N1). Three other sets (14,16,50) connect three separate phase lines (F1-F3) and corresponding neutral lines (N2-N4) to the same switch (42) which feeds both dryers with excitation voltages via relay units (40). Power can thus be drawn from either three-phase mains or at least two separate single-phase supplies.
