MPP‑P Series Wide Range Programmable DC Power Supply

The MATRIX MPP‑P Series wide‑range programmable DC power supply is a core power device for industrial testing, new energy R&D, and semiconductor validation. Breaking traditional power supply range limits, it adopts constant‑power auto‑ranging technology, delivering high voltage at low current and high current at low voltage. A single unit covers multiple voltage‑current combinations, significantly improving power utilization and reducing costs of multiple power supplies.

As an industrial‑grade programmable DC power supply, the MPP‑P Series features a 4.3‑inch high‑brightness TFT display with wide viewing angle and high resolution. It supports SCOPE waveform display, showing voltage, current, power values and curves in real time for intuitive debugging. Boasting industry‑leading precision, it offers 1mV voltage resolution and 0.1mA current resolution, with voltage accuracy <0.1%, current accuracy <0.15%, and power accuracy <0.3%. Equipped with remote voltage compensation (up to 5% of rated voltage), it eliminates long‑cable voltage drops, ensuring load‑side accuracy for precision plating, surface treatment, and power semiconductor testing.

This wide‑range programmable DC power supply integrates powerful functions for complex testing: CV/CC priority switching with rise/fall time adjustable from 20ms to 60s; three built‑in APPs: 50‑step LIST sequence programming for custom voltage‑current timing, charging mode for Li‑ion battery/capacitor charge‑discharge aging, and function generator mode outputting sine, triangle, sawtooth, rectangle, pulse, and zigzag waveforms for dynamic load testing. 128‑group data storage/recall enables one‑click parameter switching for higher efficiency.

For scalability and stability, the MPP‑P Series excels: master‑slave parallel mode (for models ≤600V) uses CAN bus for delay‑free synchronous response, flexibly expanding current and power. Standard RS485/CAN (CAN for parallel only), optional USB/LAN/dry contact/analog interfaces support local/remote control and ATE integration. OVP/OCP/OPP/UVP/undercurrent/short‑circuit protection safeguards the unit and load. Operating at ‑5°C to 45°C, it delivers industrial‑grade stability for long‑term harsh‑environment operation.

With power ratings 1KW/2KW/3KW/6KW/8KW and max 1500V/100A output, the MPP‑P Series suits aerospace testing, PV energy storage, new energy vehicles, data centers, industrial motors, power semiconductors, Li‑ion/fuel cell testing, equipment aging, precision plating, and more. It is an essential high‑precision programmable DC regulated power supply for industrial testing and R&D.

Q1: Does the MPP‑P Series support parallel operation? Any limitations?

A1: Yes, it supports master‑slave parallel mode, but only for models ≤600V. Factory pairing is required, along with optional accessories (output cables, 120Ω CAN terminator, Ethernet cable). Parallel expands current/power with delay‑free CAN sync; series operation is not supported.

Q2: What are the accuracy and resolution? Is it suitable for high‑precision work?

A2: Industry‑leading specs: voltage accuracy <0.1%, current accuracy <0.15%, power accuracy <0.3%; resolution 1mV (voltage)/0.1mA (current). Remote compensation (5% max) eliminates cable drops, fully meeting precision plating, semiconductor testing, and surface treatment needs.

Q3: What communication interfaces are available? Does it support remote control?

A3: Standard RS485/CAN (CAN for parallel only); optional USB/LAN/dry contact/analog (0–10V/4–20mA control/readback). Local/remote mode switch enables remote setup, monitoring, and waveform debugging for ATE integration.

Q4: What are the benefits of constant‑power mode?

A4: Constant‑power auto‑ranging switches voltage/current limits automatically: high voltage at low current, high current at low voltage. One unit covers multiple combinations (e.g., 1000W: 60V30A, 100V15A), reducing equipment costs and improving utilization.

Q5: What protection features does it have? How reliable is it?

A5: OVP/OCP/OPP/UVP/undercurrent/short‑circuit protection cuts output on fault. Operating temp ‑5°C~45°C, storage ‑20°C~60°C, industrial‑grade design for stable long‑term operation in harsh environments.
