ST-6680UA-AC
SAE J1772 AC EV Charger Tester
Portable North American AC charger tester for SAE J1772 conformance, interoperability, metering and field acceptance testing.

Product Overview
SAE J1772 AC EV Charger Tester
ST-6680UA-AC is a portable third-party tester for North American AC EV chargers. It supports charger R&D, factory testing, field inspection, interoperability and acceptance without relying on an EV as the test instrument. The system follows SAE J1772-2017, provides real-time data acquisition and supports optional metering, battery, GPS and environmental modules.
ST-6680UA-AC suits North American Type 1 AC charger development, factory acceptance and field commissioning. It reproduces vehicle-side charging behavior and displays charger measurements without using an EV as the test instrument. Confirm any optional interoperability, metering and battery functions against the intended acceptance procedure.
Choose the right test configuration
Interface and workflow
Type 1 / SAE J1772 AC testing with one AC 240 V / 50 A socket. NACS and Type 2 testing require a different interface configuration.
External load and connection limits
No built-in load; external load connection up to 50 A. Confirm supply, cables, load rating and test duration for energy-transfer checks.
Options and accessories
Metering, interoperability testing, internal battery, GPS and environmental modules are optional. Confirm the required functions and delivered accessories in the quote.
Procurement checklist
Confirm the delivered configuration before ordering
Interface and standards
Confirm the connector, market, protocol and exact standard editions required by the charger and test plan.
Electrical and load path
Separate socket, cable and measurement ratings from the source or external load used during sustained power tests.
Evidence and options
List required metering accuracy, message or waveform capture, fault cases, report fields and optional modules.
Acceptance and support
Agree supplied accessories, software, factory acceptance checks, commissioning, training and support boundaries.
Key Features
Designed for reliable EV charger validation.
- 01Developed against SAE J1772-2017 physical, electrical, communication and performance requirements for EV charging systems and connectors.
- 02LAN, RS232 and Wi-Fi communication support local PC control and field diagnostics.
- 03An output load socket rated up to 50 A supports external load connection. The mobile trolley case is rain-resistant, pressure-resistant, shock-resistant and corrosion-resistant for outdoor use.
- 04Supports protocol-conformance testing, optional metering verification and optional interoperability testing, with live voltage, current and charger-parameter display.
- 05Optional internal battery supports operation where no external power is available. GPS and temperature/humidity modules can provide time synchronization and precision timing.
- 06Optional metering module provides 0.05-class measurement accuracy.

Product FAQ
Common questions about ST-6680UA-AC
Does this Type 1 tester also support NACS?
The listed connector is Type 1 / SAE J1772. For NACS AC tests, compare ST-HCAC-EA / UA / NA and confirm the interface and load limits for that configuration.
Does the tester contain a power load?
No. A separate external load up to 50 A is required for sustained charging tests. Confirm voltage, cables and the energy-handling arrangement.
Which functions need to be selected when ordering?
Precision metering, interoperability testing, internal battery, GPS and environmental measurement are listed as optional. Define the required accuracy and field operating conditions in the quotation request.
