Control Transformer Wiring

Refer to page 52 for wiring schematic drawing.

Control transformer wiring.

Variety of industrial control transformer wiring diagram. A control transformer is an isolation transformer designed to provide a high degree of secondary voltage. These occur if the control devices requiring power are located away from the transformer. A wiring diagram is a streamlined traditional photographic depiction of an electric circuit.

Input output control transformer wiring mystery the only reason the wiring diagram is so specific about the if you get the two v secondary windings in parallel and out of phase. It reveals the components of the circuit as simplified forms and also the power and signal links in between the gadgets. Control circuit transformers our global control circuit transformers are designed to reduce supply voltages to control circuits providing greater safety to operators. Remove wire c if supplied from starter s control circuit.

When a long wire run is present the resistance and capacitance cause a voltage drop to the control device. 2 5 bnfc x1 h1 x2 x3 h2 h3 x0 3 2 1 3 2 1 3 2 1 connectconnect primary primary inter secondary. The transformers with protective devices include fuse blocks and or fuse clips to help protect the wiring. This will convert the starter from common control to separate control.

Variety of control transformer wiring diagram. A wiring diagram is a simplified traditional photographic depiction of an electrical circuit. It shows the components of the circuit as streamlined forms and the power and signal connections in between the devices. 240 volts delta secondary.

Control transformers are also known as machine tool transformers industrial control transformers or control power transformers. Our transformers isolate the control circuits from power and lighting circuits. A control transformer is an isolation transformer designed to provide a high degree of secondary voltage stability regulation during a brief period of overload condition also referred to as inrush current. As discussed earlier in this booklet if wire c is supplied on the starter magnet coil voltages greater than 120v you must remove it.

These single phase transformers are suitable for fixed installation in cabinets or switchboards. Bulletin 1497 control circuit transformers 6 long wire runs considerations another consideration in the selection of the transformer is long wire runs.
