Automatic Dual Power Switch With Voltage, Current, And Overload Protection
Keep a dual power supply system monitored with the TOMZN TOVPD3-63ATS relay-based automatic transfer switch. Its LCD shows operating voltage and current in real time, while built-in overvoltage, undervoltage and overcurrent protection can shut the unit down when a fault occurs.
Use it in a dual-supply installation where voltage monitoring and full line isolation matter. The 35 mm DIN rail mounting suits electrical panels, and adjustable transfer delay lets you set changeover timing for your installation.
Benefits & tips
- Check readings at a glance: The LCD displays voltage and current, while colour-coded LEDs indicate fault conditions.
- Set operating parameters: Use the front-panel controls to configure parameters to suit your setup.
- Choose the right transfer timing: The delay adjusts from 1 to 500 seconds; for instantaneous switching, consider the TOQ5–TOQ9 product line.
