power test bench
The necessity of any home appliance manufacturer is ensuring that:
End of line testing
A) any machine is compatible and reliable with any AC mains supply across the globe. This concept is essential to allow a safe and extended export of the goods regardless the Country where they’re made in.
B) any machine complies with all the local electrical safety standards and it perfectly works within certain tolerances in input of voltage, frequency and current according to the regulations enforced for electronic and electrical consumer goods. These regulations may vary from country to country.
C) during the development process of a new product, the R&D departments need to carry out a series of qualitative tests of different nature. Durability tests at different worldwide AC mains configurations are essential to check the full reliability of the new product before proceeding with the product launch stage.
Test Bench
In order to check functionality and reliability of the household appliances, once they have completed the assembly stage, they are subjected to a series of end-of-line tests most performed through test benches supplied by industrial power sources.
It’s at this stage that MCB Electronics expertise kicks in and becomes a factor with its wide array of technological custom solutions: powering test benches of home appliances multinationals has always been our core business.
AC power source
MCB AC power sources are the right solution to carry out qualitative and durable electrical tests consisting in regulating voltage, frequency and current values according to the AC mains supply configurations arbitrarily set by the manufacturer.
Power sources themselves have to be compliant to different norms and regulations (i.e. CTL-OP 110) in order to allow their use either in laboratories or production end-of-lines. MCB power sources are compliant with any regulation in force at an international level.
Worldwide Compatible
Example: a washing machine is manufactured in Poland in a production line supplied by the local Polish AC mains with 220Vac 50Hz. The manufacturer wants to ensure that the washing machine can work in US (110-120Vac 60Hz) and Japan (100Vac 60Hz). At the end-of-line It’s essential the deployment of a test bench powered by a MCB power source capable to convert the local AC mains supply to the targeted configurations.
Only when the washing machine will have passed all the qualitative tests at both the AC mains configurations it will be considered approved and ready to be brought into the market.
