The ATC Diversified UOA-240-AFN is a single-phase undervoltage monitor for 240 V AC supplies. Its relay drops out on a brownout and re-energizes when the voltage recovers, protecting motors, solenoids and other equipment.
Trip points: drop-out 202 V AC; pick-up 210 V AC. Adjustment: fixed, factory set. Trip delay: 0.5 s. Pick-up delay: 50 ms. Reset: automatic.
Output: 1 Form C (SPDT), 10 A resistive at 240 V AC; 180 VA inductive at 120 V AC. Mounting: surface mount (#8 screws), screw terminals. Approvals: cULus Listed (E55826). It operates from 0 to +55 °C and stores from -45 to +85 °C.
