Maynuo M9711 Programmable DC Electronic Load – 150 W / 30 A / 150 V
The Maynuo M9711 is a compact, high-precision programmable DC electronic load designed for professional testing of DC power supplies, batteries, adapters, and LED drivers. It supports CC, CV, CR, and CW operating modes with fast dynamic response up to 25 kHz and a current slew rate of 2.5 A/µs.
Overview
The Maynuo M9711 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 M9711 delivers stable, accurate loading across its full operating range — making it an ideal everyday workhorse for R&D, production and education.
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 M9711 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.
