Acroname MTM-Load-1
Acroname MTM-Load-1
Compact Programmable DC Electronic Load for Production & Validation Testing
The Acroname MTM-Load-1 packs serious load-testing capability into an ultra-small footprint. This single-channel electronic load handles up to 50W continuous (150W peak) for testing battery chargers, USB power outputs, amplifiers, and motor driver circuits. Software-controlled constant-current mode and precision measurements make it ideal for automated functional testing in space-constrained production environments.

Why Choose the MTM-Load-1?
Ultra-Compact Form Factor
Fits into tight test fixtures and miniaturized production setups where bench-top electronic loads won't work. The MTM footprint integrates directly with pogo-pin fixtures via PCIe-style edge connector.
Scalable for Higher Loads
Need more capacity? Connect multiple MTM-Load-1 modules in parallel for higher-demand load applications without changing your test architecture.
Precision Constant-Current Mode
100µA current resolution and better than 1% accuracy let you characterize power sources, verify current limits, and profile battery charger behavior with confidence.
Built-In Protection
Comprehensive protection against over-temperature, over-voltage, and reverse polarity prevents damage to both the load module and your device under test.
Production-Ready Durability
Part of Acroname's Manufacturing Test Module (MTM) series, ruggedized for CM and OEM environments worldwide. All pin interfaces include reverse polarity and overvoltage protection.
Flexible Integration
Connect directly to a host PC via USB, or network with other MTM modules over I2C. Program with the BrainStem API (C++, Python) or run standalone embedded programs.
