MTM-PM-1: 1-Channel DC Power Module

The MTM-PM-1, part of Acroname's Manufacturing Test Module (MTM) system, is a modular power supply designed for powering devices during manufacturing or R&D testing. The MTM-PM-1 is a one-channel software controlled, voltage and current limiting power supply. While it can provide stable, consistent and robust power to a wide range of devices, it is optimized for devices using LiPo or similar batteries; in particular, it excels at powering devices needing stable power under large transient loads, such as cellular radios (GSM, UMTS, LTE, CDMA, etc.). Accurate voltage, temperature and current measurements can be made through the powerful and cross platform BrainStem API.

For noise sensitive applications, the MTM-PM-1 features a fully linear power supply: no potentially RF-noisy switchers. When thermal and efficiency considerations are more important, the MTM-PM-1 can use its first-stage, pre-conditioning switch mode power supply (SMPS) followed by the high-accuracy, fast-response. linear stage. Regardless of the application requirements, the MTM-PM-1 provides stable and accurate power, even under transient loads up to 3A, and line transients within its operating input voltage range of 6-12VDC.

The MTM-PM-1 module also has an optional K-type thermocouple interface, allowing for remote temperature measurements from -25°C to +400°C. It also has an on-board temperature sensor, so automated tests can monitor the device under test and the test equipment temperatures itself.

The latest BrainStem development API is always available in the Download Center. The latest firwmare can be applied using the Updater utility. Check out the BrainStem Firmware Management reference entry or video for instructions on how to update your device.

MANUFACTURING TEST MODULE (MTM)

The MTM-PM-1 is part of Acroname's Manufacturing Test Module (MTM) system. Each module in the MTM series is ruggedized and designed to survive the rigors of CM or OEM manufacturing environments around the world. Pin interfaces are protected against reverse polarity and over voltage connections are designed to operate from 0˚C to 70˚C ambient, with no external cooling or fans. As a BrainStem, the MTM-PM-1 module can be connected directly to a host PC via USB, or participate in a BrainStem I2C network of multiple MTM modules. The MTM series is designed to allow your production lines to scale as simply as plugging in additional modules. Every MTM module uses a robust and inexpensive PCIe connector, though they are not PCI devices. This connector can be placed on an inexpensive PCB with test probes (aka: pogo pins) to interface to a device-under-test.

Every MTM module utilizes the BrainStem API host-based applications in C++ and Python. All BrainStems can also operate without a host PC by running embedded, user-defined programs based on the BrainStem reflex language. The BrainStem reflex API closely emulates the C++ API. Each module also features a self-discovery and notification system, allowing embedded and host based applications to determine the module's capabilities and programmatically control and direct communication between modules on the BrainStem network.
