| Datasheet | Download Datasheet |
The ATC Diversified SLD-230-ASA is a 3-phase monitor for 208/240 V AC systems. It drops its output relay out on phase loss, phase reversal, phase unbalance and undervoltage and resets once the fault clears.
Trip points: undervoltage 185-230 V AC; unbalance adjustable from 2 to 10% unbalance. Adjustment: adjustable. Trip delay: phase loss / reversal 100 ms; undervoltage 0.1-20 s adjustable; unbalance 100 ms. Restart: 30 ms. Reset: automatic upon correction of the fault.
Output: 1C SPDT, 10 A resistive at 240 V AC; 1/2 HP at 240 V AC. Mounting: plug-in, on an 8-pin octal (RB-08 or OT-08 socket) base. Indicator: LED, glows when all conditions are normal. Approvals: UL (E55826). It operates from 0 to +55 °C and stores from -45 to +85 °C.
