Complete Product Laboratory
Sanyou invested heavily and built an advanced laboratory consisting of reliability laboratory, material laboratory and office, covering an area of nearly 600m2. The laboratory owns advanced relay detection and analysis equipment, such as thermostat, glow wire, experimental machine, life test table, coercivity tester, life test checking machine, salt fog corrosion resistance test chamber, high low temperature high humidity test chamber and vibration test table, as well as high definition camera and other auxiliary equipment.

In the quality policy of “Fair, Scientific, Accurate, Effective”, the laboratory strictly follows company quality and environmental management systems (ISO9001 & TS16949; ISO14001), and actively develops qualification test, type test, grope test, sales technical support and other items. All test items are carried out according to GB/T21711.1-2008 and IEC61810-7:2006 standards. Reliability test items include:

1.Relay Comprehensive Parameter Test Pick-up Voltage, Release Voltage, Contact Resistance, Coil Resistance, Response Time, Release Time
