The MATRIX MPS-P Series is a new generation of high-quality programmable linear DC power supply designed for various testing and measurement applications. It offers precise control over voltage and current, with the ability to display voltage, current, power, and other parameters simultaneously across multiple windows. This series is equipped with an RS232 communication interface, allowing for integration into larger test systems and enabling remote control through a host computer program. Its cost-effective design makes it a suitable replacement for ordinary programmable power supplies.
Function Description
The MPS-P Series functions as a programmable DC power supply, capable of delivering stable and adjustable DC voltage and current outputs. Key operational aspects include:
- Voltage and Current Setting: Users can set the output voltage and current through the front panel using numerical keys or an adjustment knob. The voltage setting range is from 0V to the maximum rated voltage, and the current setting range is from 0A to the full rated output current.
- Data Storage and Recall: The power supply features a multi-group data storage function, allowing users to save and recall up to 99 groups of commonly used parameters from non-volatile memory. Stored parameters include voltage setting value, current setting value, OVP (Over Voltage Protection), and OCP (Over Current Protection) settings.
- Protection Functions: It includes essential protection features such as OCP, OVP, and OTP (Over Temperature Protection) to safeguard the device and the connected load from damage. When a protection state is triggered, the output is automatically turned off, and relevant prompt information is displayed on the screen.
- LIST (List Test Function): This feature enables the execution of a sequence of programmed steps, allowing for automated testing scenarios. Users can edit up to 100 steps, defining voltage, current, and dwell time for each step. The list test can be configured for different execution modes, including "Repeat," "EndHold" (output state maintained after execution), and "EndReset" (output kept closed after execution).
- Menu Settings: A comprehensive menu system allows users to configure various system parameters, including output state (Off/Keep last shutdown state), output parameters (Reset to factory default or keep last shutdown parameters), buzzer (On/Off), communication address (0-255), baud rate (4800, 9600, 19200, 38400, 57600, 115200), command protocol (SCPI/Modbus), communication terminator (CR, LF, CR+LF, LF+CR), sense function (Off/On), and reset options (No/Yes). It also allows configuration of minimum and maximum voltage and current limits.
- Remote Operation: The device supports remote control via an RS-232 communication interface (DB9 plug) on the rear panel. This allows for integration with a PC host for automated control and data acquisition. Communication settings include baud rate (9600), parity (NONE), data bits (8), and stop bits (1).
