• Upgradability: Existing T4000 units can be upgraded to T4350 specifications, ensuring you benefit from the latest advancements without needing to invest in new equipment.

Testing Using Load Emulation: PL4150 and PL4000 Load Boxes

For accurate and comprehensive testing of DC electric vehicle chargers, load emulation testing is a reliable choice that does not require ownership or use of an EV. Our latest offering, the PL4150, builds on the success of the PL4000 with significant enhancements.

PL4150 DC Programmable Load Box

• High Power Dissipation: Essential for repeatable and reproducible testing of DC Fast Chargers up to 350A. The PL4150 can also test AC chargers to their maximum amperage.
• Dual Operation Modes:
  • 400V Range: Voltage: 350V - 450V, Current: 20A to 350A
  • 800V Range: Voltage: 700V - 900V, Current: 20A to 180A
• Portable and Versatile: Designed to be mounted in the bed of a pickup truck.
• Enhanced Compatibility: Pairs with the T4350 and offers limited capacity compatibility with the T4000.

PL4000 Load Box

• Reliable Performance: A proven solution for testing AC chargers and limited DC chargers.
• Standard Testing Range: Suitable for Level 1 and Level 2 AC testing and CCS1 DC testing up to 58A.

Testing with Man-in-the-Middle (MiTM) Cables

TESCO's Man-in-the-Middle (MITM) cables provide flexibility, allowing for an EV to be used as the load in the test setup, instead of a load box.

MiTM Cables

• Seamless Integration: Allows for comprehensive testing of EV chargers using an actual electric vehicle as part of the testing process.
• Real-World Testing: Provides insights into how chargers perform under real-world conditions, ensuring they meet all required specifications.
• Versatility: Available for NACS and CCS1 chargers.

Calibration: ACT/DCT

Ensuring your testing equipment is calibrated is crucial for reliable results, and TESCO offers advanced calibration solutions to maintain the accuracy of your EVSE testing tools. Whether you prefer to have your own calibration equipment in-house or return your testers to TESCO at the recommended calibration intervals, you can rest assured that we can help to keep your EVSE field testers operating at peak performance.

ACT (AC Tester) and DCT (DC Tester)

• High Accuracy: Provides precise calibration for both AC and DC testing equipment.
• Reliable Performance: Ensures your testing tools deliver accurate results, maintaining the integrity of your testing processes.
• Easy to Use: User-friendly interface and straightforward calibration process.
