Product Introduction: TOVPD3-100VAS Three-Phase Voltage & Current Relay Protector
The TOVPD3-100VAS is a versatile three-phase voltage and current relay protector, engineered to safeguard electrical systems against voltage fluctuations, current overloads, and phase-related faults. With flexible current ratings, dual operating modes, and fully adjustable protection parameters, it is ideal for industrial, commercial, and residential three-phase electrical setups requiring reliable fault prevention and system stability.

Dual Operating Modes (ASY + SYN)
The protector offers two flexible working modes to adapt to different system requirements:
Synchronous Mode (SYN): All three-phase relays open and close simultaneously, ensuring unified control of the entire three-phase circuit (suitable for systems requiring consistent phase operation).
Asynchronous Mode (ASY): Each of the three-phase relays operates independently, allowing targeted control and protection for individual phases (ideal for setups where single-phase loads need separate monitoring).
Key Protection & Control Features
Adjustable Over-Voltage Protection: Prevents damage from excessive voltage by triggering a protective response at a user-defined threshold.
Adjustable Under-Voltage Protection: Shields equipment from low-voltage harm by activating protection when voltage drops below the set level.
Adjustable Over-Current Protection: Limits current to safe levels, avoiding overheating or damage to wires and connected devices.
Three-Phase Unbalance Protection: Detects and mitigates risks caused by unequal voltage across the three phases (a common cause of motor failure and equipment inefficiency).
Phase Sequence Protection: Prevents reverse-phase operation (which can damage motors and machinery) by monitoring and correcting phase order.
Adjustable Active & Reconnect Times: Allows customization of how quickly the protector responds to faults (active time) and how long it waits before restoring power (reconnect time), reducing false triggers and equipment stress.
