| Datasheet | Download Datasheet |
The ATC Diversified SLJ-380-ALE is a 3-phase monitor with delay on make for 350-440 V AC systems. It drops its output relay out on phase loss, phase reversal and undervoltage, with a delay-on-make timer and resets once the fault clears.
Trip points: undervoltage 290-365 V AC (one phase low); 315-396 V AC (all three phases low). Adjustment: tracks the operating-voltage setting (one phase below 83% or all three below 90%); picks up 1 V above drop-out. Trip delay: phase loss / reversal 2 s; undervoltage 2 s. Restart: 0.2-8 min adjustable (delay on make). Reset: automatic upon correction of the fault.
Output: 2C DPDT, 3 A resistive at 600 V AC; 360 VA inductive. Mounting: surface mount (#8 screws), screw terminals. Indicator: Two LEDs: green when all conditions are normal, red when the relay is energized. It operates from 0 to +55 °C and stores from -45 to +85 °C.
