An apparatus for securing an electronic component to a DIN rail including an electronic component, a latching system positioned on an end of the electronic component adapted for attachment to the DIN rail, wherein the latching system is made of a plastic material, wherein the DIN rail has a flat upper surface with two legs extending downwardly from, and perpendicular to, the flat upper surface, and a flange extends outwardly from each leg, wherein the latching system includes a recess, an upper surface above the recess having an angled slot positioned in the upper surface adapted to receive an upper flange of the DIN rail, and a lower surface below the recess adapted to have an end of a lower flange of the DIN rail positioned thereover.

A includes a plurality of power supply units, a processor, and a non-transitory computer readable medium having instructions stored thereon that, when engaged by the processor, cause performance of a set of functions. The set of functions includes detecting an overcurrent of a first power supply unit of the plurality of power supply units. The set of functions includes determining that the overcurrent of the first power supply unit corresponds to current sharing between the plurality of power supply units. The set of functions includes in response to determining that the overcurrent of the first power supply corresponds to the current sharing, suppressing an overcurrent protection mode of the first power supply.

A device comprises a processor, a memory for storing instruction code that is executable by the processor, and power supply circuitry. The power supply circuitry is in communication with the processor. The power supply circuitry comprises voltage regulator circuitry, a capacitor, a current limiter, and a switch. The voltage regulator circuitry comprises an input electrically coupled to a voltage source and an output configured to provide a regulated voltage output. The capacitor is configured to store energy derived from the voltage source. The capacitor comprises a first node electrically coupled with the output of the voltage regulator circuitry. The current limiter is in electrical communication with a second node of the capacitor and configured to limit inrush current through the capacitor during a start-up phase of the power supply circuitry. The switch circuit is in electrical communication with the second node of the capacitor. Capacitor current flows through the switch when the switch circuit is in an ON state, substantially bypassing the current limiter. The switch is transitioned to the ON state when a particular control signal is applied to the switch circuit. The switch circuit is configured to remain in the ON state when the particular control signal is no longer applied to the switch circuit.

Systems and methods of monitoring the health of an emergency power source for a luminaire node that is a node of a wireless mesh network utilized by a process control system include: utilizing, by the luminaire node, mains power to (i) route process control messages utilized by the process control system via the wireless network to thereby control an industrial process, and (ii) energize an illumination source of the luminaire node and/or maintain communications with another luminaire; storing, by the luminaire node, energy in an energy storage device configured to perform these functions during a loss of mains power; monitoring, by the luminaire node, the energy storage device to determine a health status associated with the energy storage device; and sending, by the luminaire node, an indication of the health status associated with the energy storage device via the wireless mesh network utilized by the process control system.

A system is described. The system includes at least one power supply, a control system communicatively coupled to the at least one power supply, a communication module, and at least one channel connecting the at least one power supply to the communication module.
