ABB 1SVR730750R0400 Control

Description

• The ABB 1SVR730750R0400 CM-EFS.2S, a cutting-edge single-functional voltage monitoring relay meticulously crafted for precision performance. Part of the renowned CM single-phase monitors range, this relay operates flawlessly with a rated control supply voltage spanning 24 to 240 V AC / DC. With a 2 c/o (SPDT) output boasting contacts rated at 250 V / 4 A, it delivers unparalleled reliability in voltage monitoring applications.

• The CM-EFS.2S offers four distinct measuring ranges to accommodate diverse needs: 3-30 V, 6-60 V, 30-300 V, and 60-600 V. This relay goes beyond conventional functionalities, providing window monitoring for both over- and undervoltage scenarios. Moreover, users have the flexibility to choose ON- or OFF-delay, open- or closed-circuit operating principles, with or without a latching function, tailoring the device to specific requirements.

• The versatility of the CM-EFS.2S extends to output contact configuration, allowing for 1x2 c/o (SPDT) operation for a common signal or 2x1 c/o (SPDT) for separate signals dedicated to minimum and maximum thresholds. The fixed hysteresis at 5% of the threshold value ensures optimal stability in diverse operational conditions. Adjustable tripping delay and start-up delay, ranging from instantaneous to 30 s (0, 0.1-30 s), empower users with precise control over relay performance.
