The terminal block includes a body configured to fit within the casing of the power device. The body has at least one recess formed therein. The terminal block further includes at least one current transformer sized to fit within the at least one recess of the body.

Abstract: A bi-directional differential bus interface that includes a differential transmitter having a non-inverting terminal and an inverting terminal, a differential receiver having a non-inverting terminal and an inverting terminal, and a biasing circuit that is electrically coupled to the non-inverting terminal of the differential transmitter and the inverting terminal of the differential transmitter. The biasing circuit is configured to generate a voltage between the non-inverting terminal of the differential transmitter and the inverting terminal of the differential transmitter that is approximately 200 mV or more in response to assertion of a control signal received on a control input of the biasing circuit.

Abstract: A locking assembly is provided for securing an electronic module to a chassis of a rack enclosure within a mounting slot of the chassis. The locking assembly includes a lock configured to be secured to a vertical rail of the chassis. The lock further is configured to prevent the electronic module from being slidably installed into and removed from its respective mounting slot and to prevent a latch of the electronic module from being opened when the electronic module is secured in place within the chassis of the rack enclosure. The locking assembly further includes a key configured to enable the lock to be removed from the chassis thereby enabling the installation and removal of the electronic module from the chassis.

Abstract: Systems and methods for determining liquid depth information in a condensate pan of a climate control unit are provided. The systems and methods radiate a light beam into a liquid contained in a condensate pan associated with a climate control unit. The light beam is detected at a point of the condensate pan that is below a surface of the liquid. Information related to the depth of the liquid is determined based at least in part on the detected light beam. The systems and methods disclosed herein can determine if liquid depth in a condensate pan is greater than a threshold depth and can control evacuation of the liquid from the condensate pan.

Abstract: An air pressure differential sensing system includes a conduit defining an air passage through which air flows upon application of an air pressure differential across different regions of the air passage, a flap pivotally connected to the conduit, and a sensing device mounted proximate to the air passage and separate from the flap. The flap is configured to move about a pivotal axis in response to the air flowing through the air passage. The sensing device is configured to sense an angular position of the flap about the pivotal axis, the angular position of the flap being a function of the air pressure differential.

Abstract: A system for detecting leaks on a surface, such as a floor or a bottom of an equipment cabinet, includes a sound wave generator configured to generate sound waves, a tube having a first end coupled to the sound wave generator, a second end opposite the first end, and a plurality of openings formed in the tube, and a sound wave receiver coupled to the second end of the tube. The sound wave receiver is configured to detect sound waves generated by the sound wave generator that travel through the tube. The arrangement is such that sound waves are blocked from detection by the sound wave receiver when fluid enters the tube through the plurality of openings in the tube thereby indicating a fluid leak on the surface.
