The VBA-240-ALA is a single-phase voltage band monitor designed to protect equipment by interrupting power when line voltage falls outside preset under and over thresholds. It features a DPDT relay output rated at 5A at 240VAC resistive load, with a pick-up under voltage range of 200-240VAC and over voltage range of 240-270VAC, and a hysteresis of 10V. The unit operates on 240VAC input with a maximum power consumption of 5VA, has an operate time of approximately 50ms, and a release time of approximately 0.5 seconds. It is rated for operation between 32°F and 131°F (0°C to 55°C) and weighs 5 oz. The device automatically resets when line conditions return to normal.
