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

The UOA-12-DKA is a single-phase under voltage monitor in the UOA Series, designed to protect equipment by de-energizing a relay when line voltage falls below a preset dropout level and resetting automatically when voltage returns above the pickup level. It operates on 12 VDC, with a pickup range of 10-15 VDC and a dropout range of 9-14 VDC, featuring a 1 VDC hysteresis. The unit uses a SPDT relay rated for 10 A at 240 VAC resistive load and 180 VA inductive load at 120 VAC. Response time is approximately 50 milliseconds to operate and 0.5 seconds to release. Power consumption is up to 3 watts maximum. Operating temperature range is 32°F to 131°F (0°C to 55°C). The device is mounted via RB-08 or PF083A wiring connectors and weighs between 5 and 5.5 ounces.
