Product DescriptionPlease enter the title hereThe TOVPD3-100VAS is a sophisticated three-phase voltage and current relay protector designed for robust electrical system management. It supports both asynchronous (ASY) and synchronous (SYN) operational modes, providing exceptional flexibility. In ASY mode, each phase relay operates independently, allowing for precise, per-phase monitoring and fault isolation. Conversely, SYN mode commands all three phase relays to open and close simultaneously, ideal for applications requiring unified circuit control.This device offers comprehensive protection with fully adjustable parameters. Key features include precise over-voltage and under-voltage thresholds, configurable recovery values, and adjustable delay timers for both protection activation and system recovery. It also provides critical over-current protection, which can be set from 1A to 100A or disabled (OFF), complete with a customizable action time and recovery delay.Additional safeguards enhance system reliability: three-phase unbalance protection prevents damage from unequal phase voltages, while phase sequence protection ensures correct motor rotation. A unique continuous over-current count function (C5) allows for locking the relay after a set number of faults. Furthermore, the unit includes manual voltage and current calibration (C4, U9) to maintain measurement accuracy, ensuring dependable operation in diverse industrial and commercial settings.
