Testing high-current circuits\u2014especially in EV charging systems, inverter burn-in, or industrial motor drives\u2014exposes a recurring problem: most 300A probes aren’t built for the job. They need their own power supply, overheat after 30 minutes, and crack if dropped on a factory floor. We built the ACP300 specifically to remove those constraints.<\/p>\n\n\n\n

No External Power Supply Needed<\/h3>\n\n\n\n

If you’ve ever set up a multi-channel current measurement on a drive cabinet, you know the frustration of running separate power adapters for each probe. Every extra cable is a potential failure point\u2014especially during extended automated testing.<\/p>\n\n\n\n

The ACP300 draws power directly from the oscilloscope through a patented adapter. There’s no separate supply to manage, no loose DC jack to intermittently fail at hour six of a 24-hour run. The adapter is compatible with mainstream oscilloscope platforms, so it works with what’s already on the bench.<\/p>\n\n\n\n

Practical impact:<\/strong> Cleaner setups, fewer connectors to troubleshoot, one less thing to fail during overnight tests.<\/p>\n\n\n\n

Rated for Continuous 300A Operation\u2014Not Just Burst<\/h3>\n\n\n\n

Most 300A probes are rated for short-duration use\u2014typically 30 minutes or less. That’s fine for a quick characterization sweep, but it creates real problems for production burn-in tests, EV durability cycles, or any application where you need the probe running continuously for hours.<\/p>\n\n\n\n

The ACP300 is designed for 24\/7 continuous operation at up to 300A peak. The ultra-low insertion impedance keeps the internal sensor cool under sustained high-current loads. Bandwidth covers DC to 50MHz, so it handles both the fundamental and higher-order harmonics in switching power supplies and motor drives without frequency rolloff.<\/p>\n\n\n\n

Measurement accuracy:<\/strong> Typical \u00b11%, maintained across the full operating range\u2014not just at low currents.<\/p>\n\n\n\n

Built for Industrial Environments, Not Just Lab Benches<\/h3>\n\n\n\n

High-frequency current probes typically use precision mechanical structures that don’t survive field conditions. One drop onto a concrete floor, and the jaw alignment is gone.<\/p>\n\n\n\n

The ACP300 uses a reinforced industrial housing with deliberate impact resistance. It’s been designed for the kinds of environments where probes actually get used: production lines, field service vans, rail maintenance depots. The operating temperature range of -40\u00b0C to +85\u00b0C covers most outdoor and factory environments where standard equipment would fail.<\/p>\n\n\n\n

This matters for total cost of ownership. A probe that survives a drop and keeps working is worth more than a slightly more accurate one that needs replacing every few months.<\/p>\n\n\n\n

Where the ACP300 Is Actually Used<\/h3>\n\n\n\n

New energy and EV:<\/strong> Continuous current monitoring in on-board chargers, battery pack testing, and charging station validation. The 24-hour run capability is particularly relevant here\u2014EV durability testing doesn’t stop after 30 minutes.<\/p>\n\n\n\n

Power electronics:<\/strong> Inverter and VFD testing, UPS burn-in, switching supply characterization. The DC\u201350MHz bandwidth captures the full switching waveform including high-frequency components.<\/p>\n\n\n\n

Industrial automation:<\/strong> Large motor drives, servo systems, CNC power circuits. The ruggedized housing is relevant here\u2014factory floors aren’t lab environments.<\/p>\n\n\n\n

Rail transportation:<\/strong> Traction control systems and on-board electrical diagnostics in high-vibration, high-impact environments.<\/p>\n\n\n\n

R&D and compliance labs:<\/strong> Circuit analysis, EMC pre-compliance, product verification. The \u00b11% accuracy satisfies most lab-grade measurement requirements without the overhead of a full power analyzer.<\/p>\n\n\n\n

Field service and maintenance:<\/strong> Distribution cabinet diagnostics, on-site fault analysis, outdoor maintenance. Probe runs from the oscilloscope power alone\u2014no need to source a power outlet for the probe itself.<\/p>\n\n\n\n
