IEC 60669-1 Clause 18.3 Tungsten/Halogen Lamp Load Cabinet

DFX-WD20A Tungsten/Halogen Lamp Load Cabinet is designed and manufactured in accordance with the general technical requirements of IEC 60669-1:2018 Clause 18.3 (GB 16915.1-2024 Clause 18.3), GB/T 2099.1-2021, GB/T 4943.1-2022, GB/T 7000.1-2023 and other national standards. It is suits for the interruption capacity and normal operation life test for switches for household and similar use of fixed electrical devices are used. The rated voltage of the measured attachments such as switch is not greater than 250V, and the rated current is not greater than 16A. The purpose is to evaluate the attachment, such as whether the switch can withstand the current waves that appear in normal use and the damage of electrical fatigue, and whether there is a tentacle adhesion or long -term disconnection. And test whether it has excessive wear and other harmful consequences.

DFX-WD20A tungsten filament light/halogen lamp load test cabinet has control power switch, product power current, voltage and power, frequency display instrument, load power output switch, status and light set indicator light, Current output and stop button, current (power) volume selection switch, alarm, etc. Below the front is the voltage output adjustment button. There are tungsten wire lamp load combinations, AC contactors, relays, etc. The calories use strong wind diversion cooling. There is a wiring row below, and the product is connected with the product in the test machine through the wire to output the current during the detection process.
