MPS-100 Series High-precision Programmable DC Linear Power Supply Product Details

The MPS-100 Series pure linear DC regulated power supply is one of the core products of MATRIX in the DC power supply field, specially designed for scenarios with stringent requirements on power supply precision and stability. The full series covers two power ranges of 30V/5A/150W and 60V/3A/180W, and is divided into basic models and C models with communication functions, which can flexibly meet the usage needs of different users.

In terms of precision performance, the series achieves a voltage resolution of 1mV and a current resolution of 0.1mA. At room temperature of 25℃, the setting and readback accuracy of voltage and current are controlled within an extremely low error range. The voltage ripple and noise are ＜5mVrms, and the current ripple and noise are ＜3mArms, which ensures the accuracy of precision testing from the core parameters—this is also the core advantage of linear power supplies compared with ordinary switching power supplies. The product is equipped with five groups of high-precision LED display windows, which can synchronously and real-timely display voltage, current and power values. It is matched with numeric keys and an encoder adjustment knob, supporting both precise direct value input setting and quick adjustment via the knob. The knob is designed with anti-misadjustment protection, effectively avoiding damage to equipment or test pieces caused by operational errors.

In terms of practical functions, the MPS-100 Series is equipped with a wealth of intelligent designs. First, it supports the List sequence output function, which can set up to 10 steps of sequences and 0-9999 cycles, meeting the needs of complex experiments such as dynamic testing and stepped power supply. Second, it is equipped with 9 groups of common parameter storage/recall functions, eliminating the need to repeatedly set frequently used parameters and greatly improving operation efficiency. Third, it is equipped with an intelligent temperature-controlled fan that can automatically adjust the speed according to the actual load of the equipment, minimizing the operating noise while ensuring the heat dissipation effect, and is suitable for scenarios with requirements on environmental noise such as laboratories and silent workshops.

In terms of safety protection, the product has a built-in triple comprehensive protection mechanism of over-voltage (OVP), over-current (OCP) and over-temperature (OTP). When the power supply output exceeds the set threshold or the device itself is overheated, the protection action will be triggered automatically, effectively protecting the power supply itself and the tested equipment, and avoiding safety risks in the testing process from the hardware level.

In terms of expansion and adaptability, the MPS-100C and MPS-101C models come standard with dual RS-232 and RS-485 communication interfaces, compatible with mainstream industrial protocols of SCPI and MODBUS, enabling remote control, data acquisition and intelligent system integration, and adapting to the construction needs of automated test production lines. The basic models can also be optionally equipped with RS-232 interface and SENSE function, taking into account both basic use and expansion needs. The product supports a wide voltage range of AC220V±10% or 110V±10% for rated input, which can be adapted to the power grid standards of different regions around the world. With a compact body size of only 185×105×295mm and a net weight of 4.5Kg, it is small and portable, saving space on the experiment table or production line. The operating temperature range is 0-40℃ and the humidity is ≤85%, with strong environmental adaptability, meeting the usage conditions of most industrial and scientific research scenarios.

As a benchmark product of MATRIX, the MPS-100 Series continues the brand’s high requirements for product reliability. The full series provides a 3-year official warranty, offering after-sales protection for users’ long-term use. Relying on the comprehensive performance of high precision, multi-function and high stability, it has become a cost-effective choice in the application field of DC power supplies.

Application Scenarios

1. R&D and testing of electronic components: Suitable for performance testing and aging testing of electronic components such as resistors, capacitors, chips and sensors. The precise voltage/current output can ensure the authenticity of test data.
2. Production inspection of industrial products: Applied to the factory testing of production lines for consumer electronics, small household appliances, communication modules and other products, supporting single-machine operation or integration into automated production lines, improving inspection efficiency and standardization.
3. Teaching experiments in universities and research institutions: Adapted to classroom teaching and experimental training of majors such as electronic information, electrical engineering and automation. The intuitive parameter display and simple operation method facilitate students to understand the application principles of DC power supplies.
4. Scientific research experiments in laboratories: Used for various scientific research experiments in the fields of electronic engineering, materials science, etc. The List sequence output and high-precision adjustment functions can meet the dynamic power supply needs of complex experiments.
5. Equipment maintenance and debugging: For the maintenance and debugging of small electronic equipment and precision instruments, the stable low-voltage DC output can avoid damage to the equipment caused by power fluctuations during maintenance.

A1: The core differences lie mainly in the output specifications and communication interfaces. MPS-100/100C are of 0-30V/0-5A/150W specification, and MPS-101/101C are of 0-60V/0-3A/180W specification. Among them, MPS-100C and MPS-101C come standard with dual RS-232 + RS-485 communication interfaces, while MPS-100 and MPS-101 are basic models without standard communication interfaces, which can be optionally equipped as required. The four models are consistent in size, weight, protection mechanisms and basic functions.

A2: The List sequence output function supports setting up to 10 steps of voltage/current output sequences, and each step can customize parameters and duration. The number of cycles can be set from 0 to 9999 (0 for infinite cycles). It can realize dynamic output effects such as stepped power supply and pulse power supply, and is suitable for test scenarios that need to simulate different power supply working conditions, such as dynamic aging testing of electronic components and transient response testing of circuits.

A3: Yes, it does. This series of products adopts a wide voltage design of AC220V±10% or 110V±10% for the rated input voltage, which can be adapted to the power grid standards of most countries and regions around the world. It can be directly connected to the local power grid for use without an additional transformer.

A4: The 3-year official warranty covers hardware failures of the product itself, including the maintenance and replacement of original accessories such as core circuits, display screens, adjustment knobs and communication interfaces due to non-man-made damage. Failures caused by man-made damage (such as component burnout due to operational errors, body damage caused by physical collision, private disassembly and modification, etc.) and abnormal use (such as use beyond the rated voltage/current, use in harsh environments) are not included in the free warranty scope, and the manufacturer can provide paid maintenance services.
