Draught-proof enclosure Application

 GDS is a global company based on Italy, who has 40 years' experience in electronic devices, their engineer team contacted us via email and ultimately selected us as the supplier of draught-proof enclosure after evaluating several solutions from different vendors, we thank you for the trusty and repay it with high-quality equipment.

 

Draught-proof enclosure is a equipment applied to thermal test of luminaire under the conditions of normal operation and abnormal operation as per IEC60598-1 annex D. The draught-proof enclosure is rectangular, with a double skin on top and on at least three side, and with a solid base. The double skins are of perforated metal and sprayed with black matt paint, spaced approximately 150mm apart, with regular perforations of 1mm to 2mm diameter, occupying about 40% of the whole area of each skin. At the top of enclosure shall mounted a ceiling plate or a dismountable hanging bracket with a hook to fix the luminaire at the ceiling. At the bottom of side of enclosure shall install inlet hole for the purpose of wire connection. For the sake of install luminaire, the enclosure equip with a sample holder, as per the standard, 2-layer black solid-board is applied to fix the luminaire under test. The dimension of the draught-proof enclosure can be customized as per user’s requirement, the large draught-proof enclosure will be disassembled for shipment, but user is easy to assemble it, please check the assemble video at: https://youtu.be/ENO7hZHlmAs

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5   1.  Introduction: The high current arc ignition tes t apparatus is designed according to  IEC60950-1:2001  clause 4.7.3.6 , BS/EN60950-1:2001, BS7002:2001, GB4943-2001 and UL746A, IEC60947.1:1999, GB/T14048.1-2000, IEC730.1:1993, GB14536.1-1998 and etc..  It ’ s used to measure and assess  solid insulating material against to resistance to ignition from arcing electrical sources. A power 240V(AC)/60Hz is to be supplied to the test electrodes  (fixed electrode and movable electrode) , a series (inductive-resistive) air core impedance is to be provided to yield a short circuit current of 32.5A and a power factor of 0. 5. The sample is be to positioned with the electrodes making initial contact on the surface of the sample, the circuit is to be energized and the cyclic arcing started. The timing of arcs is to be adjusted to a rate of 40 arcs/min, the rate of electrode separation is to be 254±...

what equipment can be used for IPX3 and IPX4 water ingress protection test?

1. Spray nozzle 1.  Introduction The spray nozzle hand-held device is designed according to IEC60529 figure 5, it is it is apply to verify the protection against spraying water (IPX3) and splashing water (IPX4) for large size sample. The hand-held device is consisted by spray nozzle, moving shield, counterweight, hose and pressure gauge. The spray nozzle is made of brass and has 121 holes with diameter 0.5mm (1 hole at center, 1 inner circles of 12 holes at 30 0  pitch, 4 outer circles of 24 holes at 15 0 pitch). The moving shield is made of aluminum, the counterbalanced shield is in place for IPX3 test, the water pressure is adjusted to give the specified delivery rate, the pressure to achieve this delivery rate will be in the range of 50kPa to 150kPa, and it should be kept constant during the test, the test duration is 1min/m 2  of the calculated surface of the enclosure and with a minimum duration of 5 min. For IPX4 test, the counterbalanced shield is removed fro...
