High Accuracy & Quality Multi-function 2 axis Grey Shell Digital Readout System Dro
Product Introduction
The EA series is the latest multi function DRO from Easson. It is a practical, multifunctional optical glass scale digital display for manual machine tools like Milling, Lathe, Boring machine etc.
The design is to ensure the fully function and high quality, try to use the most reasonable solution reduce the price to improve product competitiveness.
Ultra Low Temperature Rise Transformer
All Easson's digital readout unit's power supply has a linear power transformer and power filter, in order to further reduce power consumption and improve reliability, and this also 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 pass the standard EMC, we have a complete set of EMC test esd immunity tester for testing the EMC.
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
.
All Easson Digital Readout System need to do the aging test, using 3 axis signal generator counting, make sure all couting reading correctly, high temperature test and load test for 72 hours before QC procedure.
Easson Optical Linear Scale's reader head need to power on for 3 days aging test before assemble, make sure all linear scale's quality is reliable.
