| Datasheet | Download Datasheet |
The ATC Diversified SLA-230-AFN is a 3-phase monitor for 230 V AC (fixed) systems. It drops its output relay out on phase loss, phase reversal and undervoltage and resets once the fault clears.
Trip points: undervoltage 83% of nominal (one phase low); 90% of nominal (all three phases low). Adjustment: fixed, factory set. Trip delay: phase loss / reversal 0.5 s; undervoltage 0.5 s. Restart: 60 ms. Reset: automatic upon correction of the fault.
Output: 1C SPDT, Pilot duty: 180 VA continuous, 1,800 VA inrush at 120 V AC; 72 VA continuous, 720 VA inrush at 24 V AC. Mounting: surface mount, 0.250" quick-connect terminals. Indicator: LED, glows when all conditions are normal. It operates from 0 to +55 °C and stores from -45 to +85 °C.
