TK4800 Calibration Device for Portable Tester for EV Chargers

Rs. As per Client Get Quote

The TK4800 Calibration Device is a dedicated solution for calibrating both portable DC EV charger testers and portable AC EV charger testers. Designed based on the dynamic charging characteristics of modern electric vehicles, it supports two key calibration modes:

  • Steady-state electric energy measurement – for calibration under constant load
  • Dynamic electric energy measurement – for fluctuating or real-time changing loads

With high precision, wide measurement ranges, and stable performance, the TK4800 ensures accurate verification of portable EVSE testers used in field inspections, laboratory testing, and metrological verification.

Type Range Resolution Measurement Uncertainty (ppm*RD + ppm*RG) (k=2) Temperature Coefficient (15~30℃) (ppm*RD + ppm*RG)/℃
DC Voltage 300 V 0.1 mV 30 + 20 0.25 + 0.25
750 V 0.1 mV 30 + 20 0.25 + 0.25
1000 V 1 mV 30 + 20 0.25 + 0.25
DC Current 1 A 1 μA 30 + 20 0.25 + 0.25
2 A 1 μA 30 + 20 0.25 + 0.25
5 A 1 μA 30 + 20 0.25 + 0.25
10 A 10 μA 30 + 20 0.25 + 0.25
20 A 10 μA 30 + 20 0.25 + 0.25
50 A 10 μA 30 + 20 0.25 + 0.25
100 A 0.1 mA 30 + 20 0.25 + 0.25
250 A 0.1 mA 30 + 20 0.25 + 0.25
