Abstract: A flat-pack battery cabinet is disclosed. The flat-pack battery cabinet comprises a plurality of frames connected to each other by a plurality of vertical members. Each frame of the battery cabinet comprises a plurality of side brackets, a plurality of slats, a plurality of support brackets and a plurality of lock brackets. The side brackets comprises holes, grooves, and slits to attach to support brackets using fasteners to form shelf frames. The slats fit into the slits of the side brackets. The lock brackets receive the vertical members to lock the cabinet structure during assembly. The support brackets are designed to allow objects, such as batteries, to be mounted on the assembled shelves. The cabinet structure of the present disclosure is a flat-pack configuration that enables easy mounting, assembly and shipping.

Abstract: A direct current (DC) power supply system and methodology for monitoring current in the system. In embodiments, the system includes a battery power source, a conductor coupled to the battery power source, and a battery monitor for monitoring operating current. In embodiments, the battery monitor includes a substrate, a first hall-effect sensor mounted on the substrate and configured to detect a first range of electrical current, a second hall-effect sensor mounted on the substrate and configured to detect a second range of electrical current, and a controller coupled to the sensors and configured to receive voltage output signals from the sensors and determine operating electrical current flowing through the battery cable. In embodiments, the sensors are associated with different operating states of the system.

Abstract: In some embodiments, apparatuses and methods are provided herein useful to maintaining a minimum supplied voltage and/or current to an equipment. In some embodiments, there is provided a power system including at least one shelf including a plurality of rectifier slots, wherein each rectifier slot is configured to receive a rectifier unit that converts an alternating current (AC) into a direct current (DC); and at least one capacitor unit pluggable and operable in one of the plurality of rectifier slots.

Abstract: A power expansion kit includes a connection box. The connection box may include a slot configured to engage with one or more slots of one or more power shelves. The power expansion kit further includes one or more fork plugs. The one or more fork plugs may be arranged on a backside of the connection box. The one or more fork plugs may be configured to electrically couple to one or more busbars of a direct current (DC) power unit.

Abstract: A cable carrier may include a frame, a first leg extending from a first end of the frame, and a second leg extending from a second end of the frame opposite the first end. The cable carrier may also include a first bracket mounted on a first flange of the first leg, and a second bracket mounted on a second flange of the second leg. A first surface of the frame may include at least one channel configured to guide at least one cable.

Abstract: A printed circuit board (PCB) is provided and includes a plurality of edge connectors, a pin connector, and a plurality of electrical lines each electrically connecting one of the plurality of edge connectors to the pin connector. The plurality of edge connectors are positioned on the PCB to enable the plurality of edge connectors to interface with respective connectors of a plurality of configurations of circuit breakers. The configurations may include a configuration including a first type of circuit breaker and a configuration including a second type of circuit breaker. The first and second types of circuit breakers may be 1-63 ampere (A) and 80-125A circuit breakers or 80-125A and 200A circuit breakers, or may be any of a variety of other types.
