Ultra Low Temperature Rise Transformer
Easson all Digital readout power supply use a linear power
transformer and power filter, this can help our products pass by
the noice immunity and the EMC.
To reduce the total heat generation inside the ES DRO in order to
obtain long working life. An ultra low temperature rise transformer
that construct with very high permeability icron core is used,
which effectively bring temperature rise to only about 5℃.
EMC Testing equipment
To Make sure all Easson DRO products can be pass the standard EMC
standard specification, we have a complete set of EMC test esd
immunity tester.
Easson DRO have been to conforms to relevant standards for the
electromagnetic compatibility ( EMC ) as the details below:
IEC61000-4-2 / GB / T 17799-2: Electrostatic discharge immunity (
Contact discharge 6000V, air discharge 8000V )
IEC61000-4-4 / GB / T 17799-4: Electrical fast transient burst
immunity ( pulse amplitude 2000V )
IEC61000-4-5 / GB / T 17799-5: Lightning surge immunity (
Superrimposed pulse voltage peak 2000V )
Aging Test
By using the aging test, it can exposes defects in the process,
design, materials and other aspects of electronic devices before
they leave the factory. Therefore, it is of great significance
for companies to modify product designs in time, so that products
can be sold after they are aging and stable, thereby improving
product quality and market reputation.
