Safety Is Guaranteed

Protection against electric shock
Passed additional testing carried out at 35 ℃±2℃ with an IEC 61032 test probe. During the test, no DUALR3 deformation occurred and no live parts were accessible.

Adequate mechanical strength
Switches and boxes have adequate mechanical strength. After a 9-blow impact test, they show no damage and no live parts are exposed.

Insulating material
Resists abnormal heat and fire. When the PCB is placed on a glow wire at 850℃, the flame goes out within 2.8s. The PCB, base, and cover of DUALR3 have all passed the IEC 60695-2-1 glow wire test.

Resistance to heat, humidity, and aging
DUALR3 underwent many severe environmental tests to ensure its reliability in harsh environments. For example, regarding high-temperature resistance, it was kept for 1h in a heating cabinet at 100℃±0.2℃. After the test, there were no changes affecting its further use, and there was no access to live parts.

Overload Protection
Set the maximum and minimum values for voltage, current, and power. Once an appliance enters an abnormal working state, the power will automatically cut off for safety.
