    摘要: The present invention relates to a feedback device for a power supply, including a main feedback module, an auxiliary feedback module and a feedback control module. The main feedback module is adapted to sample a voltage on a main output branch of the power supply, and output a main feedback voltage to the feedback control module. The auxiliary feedback module is adapted to reduce the main feedback voltage when a voltage on an auxiliary output branch of the power supply drops. The feedback control module is adapted to control the power supply to increase its power output when the main feedback voltage decreases, so that the voltage on the auxiliary output branch is restored to normal. By using the power supply feedback device of the present invention, the circuit is simple, not only solving voltage sag problems, but also ensuring the power density and cost.

    摘要: A dust cap for a fiber optic connector is disclosed. The fiber optic connector includes a connector body having a first end and second end and a ferrule positioned at the first end of the connector body. The ferrule holds an optical fiber having an end face. The dust cap includes a housing adapted to engage the first end of the connector body to releasably couple the dust cap to the fiber optic connector and protect the end face of the optical fiber. Additionally, or alternatively, the dust cap may be configured to releasably engage an adjacent dust cap to join at least two dust caps together, and may include one or more mounting members for releasably coupling the dust cap to a support structure to thereby support the dust cap and any fiber optic connector releasably coupled to the dust cap from the support structure.

    摘要: A fiber optic cable clamp module is disclosed. The clamp module includes a conductive contact for terminating a tracer wire. The clamp module retains the fiber optic cable and provides a weather tight seal around the cable. A carrier for a fiber optic cable clamp module is also disclosed. The carrier provides a connection to ground for a tracer wire when a clamp module containing the tracer wire is installed in the carrier. The carrier also has a switch for disconnecting the tracer wire from ground without physically removing the tracer wire. A method for installing fiber optic cable using a clamping module is also disclosed.

    摘要: A filter system including a method for self cleaning the filter system of an electronic equipment enclosure where air flow is monitored either by monitoring fan performance of air flow velocity through the enclosure. The system includes two filters elements, an upstream ASHRAE or HEPA filter element to block particulate matter and a downstream PTFE filter element to block water vapor. The ASHRAE or HEPA filter element is relatively inexpensive and easy to clean. The PTFE filter element is more expensive and difficult to clean. Thus, the cheaper filter is used to protect the more expensive filter from contaminants and to increase its useful life. The method of self cleaning includes stopping the fan when a signal is received indicating a predetermined resistance to air flow which is a function of blockage of the filter elements, thereafter operating the fan at an increased rotational velocity to determine whether the fan itself is malfunctioning, thereafter slowing and stopping the fan to allow the fan to be reversed, rotating the fan in reverse for a predetermined period of time, such as five minutes, thereafter slowing and stopping the fan and returning the fan to its usual rotational velocity and direction. If the resistance to air flow is still above a predetermined level, the fan is again slowed, stopped and reversed and then returned to normal operation. The reversal operation can be conducted a multiple number of times, however, after a predetermined number, a signal is sent requesting maintenance

    摘要: A more efficient cooling system for densely packed electronic components for use in an out-of-doors equipment enclosure. An array of cooling assemblies are placed on heat generating components mounted to printed circuit boards mounted in enclosure racks. Each board has a manifold for intake and exhaust of refrigerant, and larger rack manifolds are substituted for rails and are attached to a backplane. A hybrid package including a ceramic hybrid power module and an attached array of cooling assemblies provide even more density of components and improved cooling.
