Description: The MP-P2 Power Supply is engineered to provide power to the motherboard and its associated plug-on boards, including the MP-09 Microprocessor Board, disk controller board, memory boards, and up to eight interface boards within the SWTPC Computer system. It comprises a power transformer, a bridge rectifier, two large filter capacitors, and a power interconnect board. The power interconnect board serves as a circuit board that supports protection fuses, a +16 volt rectifier with a filter, and the motherboard wiring connector, which significantly facilitates the interconnection and servicing of the unit.
The MP-P2 Power Supply operates by converting alternating current (AC) from the mains into the necessary direct current (DC) voltages required by the various components of the SWTPC Computer system. The power transformer steps down the high voltage AC to a lower voltage suitable for rectification. The bridge rectifier then converts this AC voltage to pulsating DC, which is smoothed out by the two large filter capacitors. These capacitors store energy and reduce voltage fluctuations, providing a stable DC output.
The power interconnect board plays a crucial role in the overall functionality of the power supply. It houses the protection fuses, which safeguard the system against overcurrent conditions, ensuring that the components are protected from potential damage. The +16 volt rectifier, located on this board, is responsible for supplying the necessary voltage to the motherboard and other connected boards. The filter associated with this rectifier further stabilizes the output voltage, ensuring reliable operation.
Additionally, the motherboard wiring connector on the power interconnect board is designed to simplify the process of connecting and disconnecting various components. This feature is particularly beneficial during maintenance and upgrades, allowing technicians to efficiently service the unit without extensive disassembly. Overall, the MP-P2 Power Supply is a critical component of the SWTPC Computer system, providing reliable power distribution and enhancing the ease of serviceability.The MP-P2 Power Supply is the supply designed to power the mother board and its complement of plug-on boards including the MP-09 Microprocessor Board, disk controller board, memory boards and up to eight interface boards on the SWTPC Computer system.
