Relay-Based Automatic Dual Power Switch

DESCRIPTION

The TOVPD3-63ATS represents a relay-type automatic transfer switch engineered for dual power supply systems. What sets it apart from standard ATS products is its built-in protection against both voltage irregularities and overcurrent situations, accompanied by a real-time monitoring display for voltage and current parameters. A key safety feature is its capability to interrupt both the phase and neutral lines at the same time, providing comprehensive isolation. This unit is particularly suitable for installations where electrical safety cannot be compromised.
