3-Phase Voltage Unbalance Monitor
The MODEL 2002Y 3-Phase Voltage Unbalance Monitor provides essential protection for industrial systems. It detects voltage imbalances across three phases, preventing potential equipment damage and operational disruptions. With an adjustable unbalance threshold from 2% to 10% and a rapid 150ms response time, it ensures timely intervention. The unit operates across a 50Hz-60Hz frequency range and accommodates various phase-neutral and phase-phase voltage configurations up to 480VAC. Its DPDT contact configuration and 10 amp at 240VAC resistive contact rating offer reliable control for connected equipment. Designed for surface mounting, its ABS plastic enclosure ensures durability in diverse environments. The monitor features automatic reset and an adjustable dropout time from 1 to 20 seconds, enhancing operational flexibility. A 5-year unconditional warranty underscores its robust design and long-term performance, minimizing maintenance concerns.
