UL 859 Cord Flexing Tester, Cord flexing test apparatus
Product Introduction
The Household Appliance Supply Cord Flexing Test Apparatus is specially designed and manufactured according to IEC60335-1-clause 25.14, IEC60335-2-23-cl.11.101, UL859-clause 49, UL859-clause52. It is used to check the power cord flexing (bending) resistance performance of small household appliances (such as coffee pots, electric irons, hair dryers, blower-stylers, heated air combs or brushes, hair dryer-curling iron combinations, wall-hung hair dryers, or the hand unit of a wall-mounted hair dryer) and lamps. It is also applicable for power cord flexing endurance testing of plugs and sockets.
The device is controlled by PLC and operated by a 7-inch color human-machine interface. The bending angle, number of tests, and test rate can be preset. The test is automatically carried out according to the start-up test. When the test reaches the preset number of times, the device automatically stops and gives a test completion signal prompt. The built-in load of the device can also supply load current to the test sample.
