Overview

The Macromatic VWE120A is a voltage band monitor relay designed to protect equipment from overvoltage and undervoltage conditions. Operating within a nominal voltage of 120V AC, this relay provides essential voltage band protection for a variety of industrial applications. It features user-adjustable over- and under-voltage settings, allowing for precise calibration to specific system requirements. An adjustable time delay is also included, offering further customization to prevent nuisance tripping. The VWE120A is part of Macromatic's VWKE Series, known for its compact 17.5mm width and reliable performance. This unit offers a pick-up setting of 120V AC and a drop-out setting adjustable from 30-95% of the pick-up setting, with a time delay range of 0.1-10 seconds. Its output contacts are rated at 15A @ 240V AC SPDT, ensuring robust switching capabilities.

The 201A-AU is a 3-phase, auto-ranging, dual-range voltage monitor that protects 190-480VAC, 50/60Hz motors regardless of size. Has user adjustable 1-30 second trip delay, manual or 1-500 second restart delay, and 2-8% voltage unbalance trip point. The product also provides a user selectable nominal voltage setpoint and the voltage monitor automatically selects between the 200V and 400V range. The Model 201A-AU includes advanced single LED diagnostics, where five different light patterns distinguish between faults and normal conditions. This unique microcontroller-based voltage and phase-sensing device constantly monitors the 3-phase voltages to detect harmful power line conditions. When a harmful condition is detected, the 201A-AU's output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to acceptable levels.
