With the rapid proliferation of global electric vehicle charging infrastructure, versatile portable testing equipment has become a necessity to verify the electrical safety, communication compatibility and overall performance of Mode 3 AC charging stations. The PEAKMETER PM701 series, consisting of PM701E, PM701U and PM701UT, are professional EVSE adapters engineered in full compliance with IEC/EN 61851-1 and IEC/HD 60364-7-722 standards, ideal for on-site commissioning, routine maintenance and fault diagnosis of charging equipment.
Boasting an IP54 lightweight handheld design, the three variants cover global mainstream connectors: Type 2 for Europe, Type 1 for North America and Tesla NACS, delivering a unified testing solution without real EVs.
It integrates complete simulation functions. PP knobs mimic 13A–63A cable capacities, while CP switches recreate four vehicle charging states (A/B/C/D) to restore 1kHz PWM signals. Quick buttons simulate CP short-circuit and PE earth faults to test charger safety interlocks. PM701U and PM701UT feature an exclusive 6mA GFCI leakage test for North American compliance.
Safety is prioritized via a PE Pre-Test probe that alerts stray hazardous voltage on protective earth. Multiple 4mm measurement terminals access L1/L2/L3/N/PE for insulation, impedance and continuity tests; CP output ports connect oscilloscopes to analyze PWM waveforms. A fused 10A rear socket enables load and meter calibration, covering all standard mandatory inspection items.
Stable between 0–40°C and up to 2000m altitude, the unit features easy cleaning and fuse replacement. For electricians, charger manufacturers and third-party labs, it simplifies testing procedures, boosts efficiency and ensures reliable, compliant operation of worldwide AC charging infrastructure.
Reliable EVSE test adapters are core tools for validating Mode 3 AC charging stations, delivering full vehicle and cable simulation without physical EVs. PEAKMETER PM701 series adapters cover Type 2, Type 1 and NACS connectors, fully compliant with IEC/EN 61851-1 standards for installation acceptance, periodic maintenance and fault diagnosis.
Equipped with PP and CP adjustment knobs, they simulate various cable current ratings and four EV charging states to restore standard PWM communication signals. One-click buttons trigger CP short and PE earth fault simulation, while PM701U/UT support exclusive GFCI leakage testing for North American compliance. A built-in PE Pre-Test probe alerts hazardous stray voltage to protect operators.
Multiple 4mm measuring terminals support insulation, impedance and phase voltage tests, with CP signal ports for oscilloscope waveform analysis and a fused load socket for meter calibration. Lightweight IP54 handheld design adapts to outdoor sites, simplifying testing workflows and ensuring charging station safety and stable operation.
Safe operation of AC EV charging systems hinges on rigorous earth protection and leakage current verification, which prevent electric shock hazards caused by wiring defects, insulation degradation or ground circuit failures.
Standard EVSE inspection relies on dedicated test adapters to replicate real-world fault conditions without actual vehicles. The PEAKMETER PM701 range carries out mandatory PE pre-checks before any measurement, instantly alerting users to dangerous live voltage on protective earth lines.
Models tailored for North American markets integrate specialized GFCI leakage simulation, generating controlled 6mA residual current to assess the charger’s rapid cut-off capability. Users can manually trigger PE disconnection and CP short-circuit faults to validate the equipment’s safety interlock response.
Multi-channel measurement terminals enable precise testing of insulation resistance, loop impedance and protective conductor continuity. All safety assessments align with international EV charging standards, offering field technicians a compact, reliable solution to fully audit leakage risks and earth circuit integrity for charging infrastructure.
EV supply equipment (EVSE) demands full-spectrum electrical validation to meet global compliance standards and eliminate hidden operational hazards. Comprehensive electrical testing covers conductive circuit integrity, communication signal performance, protective interlock response and load operation, forming a complete inspection system for Mode 3 AC charging stations.
Specialized EVSE test adapters deliver all-around measurement capabilities without physical electric vehicles. Beyond basic ground and leakage checks, the PEAKMETER PM701 series enables full-range electrical verification: adjustable PP resistance simulates diverse charging cable current specifications, while CP state switches reconstruct all vehicle connection modes to analyze PWM communication waveforms via oscilloscope access.
The device’s multi-channel 4 mm safety terminals facilitate precise readings of phase voltage, neutral continuity, insulation resistance and loop impedance. Built-in fault trigger buttons artificially induce CP short circuits and PE earth breaks to assess the charger’s automatic power-off protection logic. The integrated load socket supports real load simulation and energy meter calibration, completing full functional electrical verification.
Engineered for field deployment, this all-in-one testing tool unifies multiple discrete measuring instruments into a compact handheld unit. It streamlines end-to-end electrical acceptance testing, guarantees consistent, repeatable test data, and helps technicians fully validate every electrical parameter of EVSE to comply with IEC international specifications.
