Abstract
Networked automation systems having electric actuation from a high voltage source. The electric actuator includes a switch mode power supply coupled to the high voltage source as a principal power source. The networked automation systems include a controller device having an output network port wired to an input network port of the motor drive. The controller device is also coupled to an auxiliary source of power. Thus, a regulation circuit of the switch mode power supply can be coupled to the auxiliary source of power, thereby providing power for the regulation circuit at start up.
Claims15
A networked automation system comprising:
- a first motor drive including:
- an IN network port;
- an OUT network port;
- a switch mode power supply providing a low voltage source control power for the first motor drive;
- and
- a regulation circuit for the switch mode power supply,
- a second motor drive including:
- an IN network port connected to the OUT network port of the first motor drive;
- a switch mode power supply providing a low voltage source control power for the second motor drive;
- and
- a regulation circuit for the switch mode power supply;
- a high voltage source powering the first motor drive;
- and
- wherein, the OUT network port of the first motor drive is coupled to the IN network port of the second motor drive for providing auxiliary power from the switch mode power supply of the first motor drive to the regulation circuit of the second motor drive at start up.
A motor drive assembly comprising:
- a high voltage source;
- an auxiliary power source;
- and
- a switch mode power supply coupled to the high voltage source, the switch mode power supply comprising,
- a regulation circuit for the switch s DOW supply, and
- at least one IN port configured to receive auxiliary power from the auxiliary power source,
- wherein the auxiliary power powers the regulation circuit to allow the switch mode power supply to start up and operate.
A networked automation system comprising:
