VDH30 test system

The VDH 30 consists of a conductive sphere with a diameter of 210 mm, a connecting wire with a length of 300 mm, a protection network for the EMI receiver, and a wooden tripod.

The Van Der Hoofden test head can determine the frequency range of human exposure to electromagnetic fields caused by brightness from 20kHz to 10MHz. The measurement is based on IEC 62493 version 2.0: 2015-03. Through the different coupling methods between the lamp and the person, the degree of exposure of a person to the electromagnetic field can be obtained. Part of the exposure is based on the capacitive coupling between the lighting device and the person. This creates an induced internal electric field, which must be evaluated using an EMI receiver and Van Der Hoofden test head.

The VDH 30 consists of a conductive sphere with a diameter of 210 mm, a connecting wire with a length of 300 mm, a protection network for the EMI receiver, and a wooden tripod.

The EMI receiver measures voltages between 50Ω. It must be connected to the N connector of the protection network. In order to determine whether the luminaire meets the standard, the measured voltage must be converted into an induced internal electric field. The weighted and aggregated induced internal electric field compliance factor F caused by the external electric field in the frequency range of 20kHz to 10MHz should not exceed a value of 1. If F does not exceed 1, the DUT is compliant. These calculations can be performed using the software provided with the device.
