A method for managing a number of power supply units (PSUs) of a power supply device is provided. A total operation time of each PSU is counted. A number of the PSUs to be assigned to work is determined according to a load value of a load connected to the power supply device. Which of the PSUs will be assigned to work and which of the PSUs will be assigned to idle are determined according to the total operation time of each PSU and the determined number of the PSUs to be assigned to work. The PSUs to be assigned to work are controlled to enter a work state, and the PSUs to be assigned to idle are controlled to enter a standby mode.

Power supply device and power management method

A voltage-drop testing system, including a voltage-drop control apparatus, and a voltage-drop testing method adapted for the voltage-drop testing system based on LABVIEW department platform. When the LABVIEW department platformis running, different groups of test data may be transferred to the PLD tester, when the PLD testerfinishes the testing based on all groups of test data, the PLD testerfeeds back the test results to the LABVIEW department platform, and the LABVIEW department platformcreates the voltage-drop testing graphic frame displaying the test results for the electronic device under testfor the convenience of a user.

Voltage-drop testing system, voltage-drop control apparatus, and method thereof

A power supply system is for supplying power to a number of loads, and includes a number of plugs, a number of power supply modules of the same type, and a number of current distribution modules. The plugs are respectively used for connecting to an external power source, to obtain alternating current. The power supply modules are connected to the respective plugs for converting the alternating current into direct current and providing the direct current to the loads according to the requirements of the loads. Each power supply module includes a positive electrode and a negative electrode, both of which connect to a corresponding load. The current distribution module electrically connects the positive electrodes to each other, and electrically connects the negative electrodes to each other, such that the power supply modules are connected in parallel.

Power supply system for rack server

A power supply system for supplying power to a number of loads includes a number of power supply modules, a bus, and a control module. The power supply modules each comprises an input terminal receiving an input power and an output terminal outputting an output power, the input terminals of power supply modules having the same input power. The bus is configured for connecting the loads to the power supply modules. The control module calculates the ratio of the total output power of the power supply modules to the input power of one power supply module and controls the connection and the disconnection of the power supply modules according to the ratio.

System for maintaining power efficiency of power supply modules by selectively connecting and disconnecting power supply modules from a plurality of power supply modules based on the calculated power supply module output to input ratio of each module

A power supply consists of a main body including a base and a cover. The base defines a cavity and a through hole communicating the cavity with the exterior. The cover covers the cavity. The circuit board is received in the base. The connector includes a connector body, a conductive pad, and a conductive fastener. The connector body is disposed within the cavity. The conductive pad is fixed to the connector body, connected to the circuit board, and defines a threaded hole. The conductive fastener is received in the threaded hole. The cable goes through and is connected to the conductive fastener.

Power supply

A power managing system includes a power supply, a first converter, a second converter, and a complex programmable logic device. The power supply outputs a first verification signal and a first power upon the condition that the power supply receives a power supply on signal from a motherboard. The first and second converters convert the first power to a second power, a third power, and output a second verification signal, a third verification signal respectively. The complex programmable logic device outputs an enable signal to the motherboard to make the motherboard receive the first, the second, and the third powers upon the condition that the complex programmable logic device receives the first, the second, and the third verification signals.
