RS PRO Digital Voltage Monitoring Relays


RS PRO is proud to present a complete range of control monitoring relays designed for single-phase or 3 phase systems. Each relay is packed with excellent features to ensure effective protection against all types of low voltage faults. These high-quality monitoring devices offer over-voltage and under-voltage protection, protect against voltage phase sequence, phase loss, and phase asymmetry, over & under frequency, and neutral open.

Display Screen


The front panel details on the display screen include fault window and menu feature parameter, line or phase voltage, delay timer status, time in seconds, percentage asymmetry, frequency in Hz, voltage, Instantaneous voltage, or other settable parameters and relay status.
