MCB Home Appliances Application

Home Appliance Industry

The necessity of any home appliances manufacturer is ensuring that:

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.

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.

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.
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.
