ETEC Single Phase 100A 220VAC PC class Automatic Transfer Switch City Grid-PV Energy And Inverter EK2R.Overview
Dual power automatic transfer switches are newly developed miniature household power transfer switches. This switch is mainly used to test whether the normal or standby power supply is normal. When the normal power supply is abnormal, the backup power supply will work immediately to ensure the continuity, reliability, and safety of the power supply.
Check the control power supply voltage: 50/60Hz AC220-240V. The connecting wire of the control circuit should not be too long. The cross-sectional area of the copper wire should be greater than 2.0mm.
