Portable Electric Vehicle Charger Test System (T4350)
Rugged, Portable, and Built for the Field
The TESCO T4350 EVSE Test System is a next-generation electric vehicle charging station analyzer designed for high-accuracy measurement, field durability, and universal compatibility.
Engineered and manufactured in the USA, the T4350 delivers lab-grade precision (±0.05%) for voltage, current, and power—making it the trusted solution for utilities, field engineers, service providers, and EVSE testing laboratories.
Supports CCS1 & Tesla Charging Standards (Optional Adapters)
The T4350 supports both AC and DC charging for CCS1 and Tesla, providing a complete testing solution in a single, portable unit.
Supported Charging Modes:
- CCS1 AC: Up to 80A at 240VAC (SAE J1772, North America)
- CCS1 DC: Up to 650A peak, 350A sustained, 1000VDC
- Tesla AC: Up to 80A at 240VAC
- Tesla DC: Up to 650A peak, 350A sustained, 1000VDC (SAE 3400, North America)
This broad coverage ensures the T4350 meets the needs of all major charging deployments—from utility-owned Level 2 stations to high-power public DC fast chargers.
