| Datasheet | Download Datasheet |
The ATC Diversified PBC-400-ALE is a 3-phase voltage band monitor for 400 V AC (delta) systems. It drops its output relay out on undervoltage and overvoltage (each phase) and resets once the fault clears.
Input range: 485 V AC max. Trip points: undervoltage 325-385 V AC adjustable; overvoltage 415-475 V AC adjustable. Trip delay: undervoltage 0.5 s. Restart: 100 ms. Reset: automatic upon correction of the fault.
Output: 2C DPDT, 10 A resistive at 240 V AC; 360 VA inductive at 600 V AC; 1/2 HP. Mounting: surface mount (#8 screws), screw terminals. Indicator: LEDs glow on a fault: one for over, one for under. Approvals: cULus Listed, Industrial Control Equipment 496Y (E55826). It operates from 0 to +55 °C and stores from -45 to +85 °C.
