Mueller Electric Company Monitor - Relay Output UOA-12-DLA

The UOA-12-DLA is a single-phase under voltage monitor in the UOA Series, designed to protect equipment by de-energizing output when voltage falls below a preset drop-out level and re-energizing when voltage rises above the pick-up level. It operates on 9-14 VDC for drop-out and 10-15 VDC for pick-up, with a 1 VDC hysteresis. The device features a SPDT relay rated at 10 A at 240 VAC resistive or 180 VA inductive at 120 VAC. It has an approximate operate time of 50 ms and a release time of 0.5 sec. Power consumption is max 3 W, with an operating temperature range of 32°F to 131°F (0°C to 55°C). The unit weighs between 5 and 5.5 oz. The suffix 'L' indicates a locknut adjustment, and 'A' indicates Style A relay configuration.
