Acroname MTM-PM-1

The Acroname MTM-PM-1 (S65-MTM-PM-1) is a single-channel, software-controlled DC power module for Acroname's Manufacturing Test Module (MTM) system. It supplies a programmable, current-limited rail to the DUT during functional test and reports back the current the board is actually drawing, so supply sequencing and current-signature checks can be scripted from the host alongside the rest of the test.

Its output range and transient behaviour are aimed squarely at battery-powered products: 1.8 V to 5.0 V covers LiPo-class rails, and the module holds under 1 % droop at 28 µs into a 2 A transient, which is what makes it usable on devices with cellular radios that pull hard in bursts. Reach for the PM-1 when the DUT needs a clean, measured supply; where the fixture instead needs to sink current, the MTM-Load-1 is the counterpart module.

• Output 1.8 to 5.0 VDC, 50 µV setting resolution, better than 1 % precision
• Up to 3 A continuous; current limit precision 1 %
• Current measurement 0 to 3.3 A at 50 µA resolution
• Load transient response under 1 % droop at 28 µs from a 2 A transient
• Kelvin (4-wire) sense feedback
• K-type thermocouple interface, −25 °C to +400 °C, plus on-board thermal measurement
• Fully linear or switchable SMPS-to-linear operation
• Input power 6.0 to 12.0 VDC; USB and I2C control via the BrainStem API
