APEC 2025 test equipment: power sources and loads

March 26, 2025 By Martin Rowe Leave a Comment

DAQ3120

Powering electronic devices requires the testing of power supply and charging circuits, battery management systems (BMSs), and battery cells. Many of these circuits require voltage, current, and power measurements, plus numerous others. Oscilloscopes and probes let you see the waveforms in power-delivery circuits, but the circuits themselves may need simulated batteries and simulated loads. That’s […]
