MVS
Series
5.9
Control Supply Transformer
The MVS requires a low voltage control supply (110~130 VAC or 220~240 VAC).
If low voltage is not available, a transformer is required. Use a transformer with
primary voltage matching the mains voltage, and secondary voltage of 110 VAC.
Use a single phase 500 VA transformer with protection fuses on both the primary
and secondary sides (refer to
Diagram 2: Complete Power Circuit Configuration
on
page 18).
Diagram 2: Complete Power Circuit Configuration
MVS power circuit with main contactor, bypass contactor, main isolator/ earth
switch, R Rated fuses and control supply transformer. Configured for two-wire
start/ stop control.
