Abstract
Exemplary embodiments are disclosed that include multi-voltage contactors, controls, and related methods.
Claims25
A relay switch control configured for connection with one or more components and one or more line voltage sources, the relay switch control comprising:
- a processor;
- a relay operable by the processor to electrically connect or disconnect the one or more line voltage sources;
- and
- a control circuit configured to be coupled for communication with and/or transmit control signals to the processor;
- wherein the processor is configured to be operable for determining input voltage and adjusting brownout threshold;
- and
- wherein the relay switch control is configured to:
- at power up, determine a voltage level set within a memory;
- if the voltage level is set at a first voltage level within the memory, set the brownout threshold at a first brownout threshold;
- if voltage level is set at a second voltage level within the memory, set the brownout threshold at a second brownout threshold;
- and
- if voltage level is not set within the memory:
- monitor input voltage;
- determine if the monitored input voltage is stable within a first voltage range;
- set the voltage level at the first voltage level within the memory and set the brownout threshold at the first brownout threshold if the monitored input voltage is determined to be stable within the first voltage range;
- and
- set the voltage level at the second voltage level within the memory and set the brownout threshold at the second brownout threshold if the monitored input voltage is not determined to be stable within the first voltage range.

A contactor configured for connection with a load and a power supply, the contactor comprising:
- a processor;
- a relay operable by the processor to electrically connect or disconnect the power supply;
- and
- a control circuit configured to be coupled for communication with and/or to transmit control signals to the processor, the control circuit including a common connector, a first connector, and a second connector;
- whereby the contactor is configured to be selectively operable with:
- a first voltage input when a load operable with the first voltage is connected to the first connector and the common connector;
- and
- a second voltage input higher than the first voltage input when a load operable with the second voltage is connected to the second connector and the common connector;
- wherein:
- the contactor further includes a fuse coupled with and/or in the first connector that is configured to protect against miswiring;
- and/or
- the processor is configured to be operable for determining input voltage and adjusting brownout threshold;
- and/or
- the contactor further includes a cover or door movable relative to the first and second connectors such that only one of the first connector or the second connector is available for connection at a time.
11 more elements
A method of adjusting brownout threshold of one or more components, the method comprising determining a voltage level set within a memory, and further comprising:
- if the voltage level is set at a first voltage level within the memory, setting the brownout threshold at a first brownout threshold;
- if voltage level is set at a second voltage level within the memory that is higher than the first voltage level, setting the brownout threshold at a second brownout threshold higher than the first brownout threshold;
- and
- if voltage level is not set within the memory, monitoring input voltage, determining if the monitored input voltage is stable within a first voltage range, and
- setting the voltage level at the first voltage level within the memory and setting the brownout threshold at the first brownout threshold if the monitored input voltage is determined to be stable within a first voltage range;
- and
- setting the voltage level at the second voltage level within the memory and setting the brownout threshold at the second brownout threshold if the monitored input voltage is not determined to be stable within a first voltage range.
