Relay-type dual-power transfer switch

GENERAL

TOVPD3-63ATS is a relay-type dual power conversion switch. Compared with the traditional ATS, this device has added voltage and current protection functions, and can display real-time voltage and current. At the same time, this device cuts off both the neutral wire and the live wire simultaneously, which makes it even safer. If you have a high demand for security, you might want to consider this device.

FEATURES
1. Microcontroller based
2. Digit display for operating voltage and current value
3. Protect electrical device against over/under voltage and over current
4. Voltage measurement accuracy ≤1%
5. Parameters setting by keys
6. LEDs indication for over/under voltage and over current faults
7. DIN Rail mounting
8. Neutral lines & phase lines are all protected by relays
