Quantity

The Maynuo M9712 is a 300W programmable DC electronic load (0–30A / 0–150V). It supports six operating modes — CC, CV, CR, CW, CC+CV, and CR+CV — with fast dynamic response up to 25 kHz and a current slew rate of 2.5 A/µs.

Overview

The Maynuo M9712 is a compact, high-precision programmable DC electronic load designed for professional testing of DC power sources. It provides four primary operating modes — constant current (CC), constant voltage (CV), constant resistance (CR) and constant power (CW) — plus combined CC+CV and CR+CV modes, with 0.1 mA / 1 mV resolution and up to 0.03% basic accuracy for repeatable, lab-grade measurements. From validating a bench power supply to profiling a battery pack or qualifying an LED driver, the M9712 delivers stable, accurate loading across its full operating range — making it an ideal everyday workhorse for R&D, production and education.

Accuracy

A fast dynamic mode (up to 25 kHz, 2.5 A/µs) reproduces real-world transient and load-step conditions, while built-in battery-capacity testing, short-circuit simulation and automatic multi-step test sequences cover everyday R&D and production work. The M9712 is housed in a rugged 19-inch rack-mountable chassis with a bright VFD display and a temperature-controlled fan, and can be fully remote-controlled over optional RS-232 / RS-485 / USB using the free PC software.

Typical applications

Power supply & SMPS testing
