Fast Charging Current Probe for DC Charging Pile Testing
Measure high-current DC fast charging waveforms, charger module current and output ripple with durable AC/DC current probes designed for power electronics testing.
DC fast charging systems require high output current, fast protection response and stable power conversion. Current measurement must cover both large current magnitude and dynamic waveform details.
Challenges in DC Fast Charging Testing
DC fast charging systems require high output current, fast protection response and stable power conversion. Current measurement must cover both large current magnitude and dynamic waveform details.
High Output Current
Output current from hundreds of amps to over 1000A in high-power chargers.
Current Ripple & Transients
Current ripple and transient behavior from power modules must be captured accurately.
Protection Verification
Protection verification during overload, short-time surge and fault simulation.
Long-Duration Testing
Long-duration burn-in and aging tests for charger modules.
Compact Cabinets
Difficult measurement points inside compact cabinets or around thick cables.
Integration Complexity
Integrating measurement safely into fast charging test workflows without disruption.
How ACP Probes Help
ACP series AC/DC current probes help charger engineers measure output current and internal module current without cutting cables or interrupting the system. Their high current ranges and wide bandwidth make them useful for both routine validation and waveform-level debugging.
DC Output Measurement
Measuring DC output current in charging piles and charger modules.
Ripple & Surge Capture
Capturing ripple, surge and transient current events.
Long-Duration Support
Supporting long-duration high-current testing without derating.
Simplified Setup

Frequently Asked Questions
Which ACP model should be used for DC fast charger testing?
ACP1000 is recommended for many charger module and output current tests. ACP3000 is recommended for ultra-fast charging systems or test points where current may exceed 1000A.
Can ACP probes measure DC charging output current?
Yes. ACP probes are AC/DC current probes and can be used for DC output current, ripple current and transient current measurement.
Can the probe be used during long burn-in tests?
Yes. ACP series probes are designed for long-duration high-current testing and product data indicates no maximum current frequency derating.
What if the charging cable is too thick?
For special cable diameter or cabinet layout requirements, a customized AC/DC current probe can be configured with suitable jaw size and cable length.
Does the probe work with different oscilloscopes?
The ACP series uses a replaceable adapter design intended to support multiple oscilloscope interface generations. Compatibility should be confirmed for the target oscilloscope model.
