IEC 60669-1 Clause 19.1 and 19.2 Externally Ballasted Fluorescent Lamp Test Load Cabinet

The DFX-20 Externally Ballasted Lamp Test Load Cabinet (Resistive, Inductive, and Capacitive Load cabinet) can simulate different types of resistive, inductive, and capacitive load conditions. By adjusting the output electrical parameters, it provides a suitable operating environment for relevant electrical accessories, thereby verifying whether the performance of the electrical accessories meets the standards under the corresponding loads. The equipment has a built-in electrical parameter monitoring module that can acquire key data such as AC voltage, current, power, and power factor in real time. It also has a preset counting function, which can set the number of tests according to testing needs, meeting the standardized load test operation procedures. It can also be used in conjunction with corresponding life testing and bending testing equipment to form a complete electrical accessory performance testing solution.

Standards:

Specification:
• Output modes: Resistive, Inductive and Capacitive
• Voltage output range: 0~275V; Accuracy: 1V
• Power Factor PF: Adjustable from 0.30 to 0.98 when current is below 16A; Adjustable from 0.60 to 0.98 when current is above 16A; Resolution of Power factor resolution is 0.01
• Built-in digital power meter; It can measuring AC voltage, current, power, and power factor; Accuracy: ± (0.4% of reading + 0.1% of range + 1 digit)
