Cummins RA Series ATS Adjustable Voltage Relay Kit
Field-installable upgrade kit for Cummins RA Series automatic transfer switches. Replaces the standard voltage sensing relay with an adjustable trip relay capable of detecting brownout and over-voltage conditions. Enables faster generator starts and load transfers in areas where voltage frequently drops below acceptable thresholds without a full outage. UL certified.
Features & Benefits
Adjustable Voltage Trip Points Installer-selected over-voltage and under-voltage thresholds eliminate the one-size-fits-all limitations of the standard relay. Dial in the exact trip points required for local grid conditions or market requirements.
Brownout Detection Detects voltage sag conditions that fall below acceptable levels without dropping to zero. Triggers a generator start and load transfer before equipment is exposed to damaging low-voltage conditions — something the standard relay cannot do.
Over-Voltage Protection Monitors for voltage spikes above the set threshold. Transfers load to the generator before connected equipment is exposed to damaging over-voltage conditions.
Adjustable Start Delay 0–10 second configurable delay before generator start signal is issued. Prevents nuisance starts on momentary voltage fluctuations.
Simple Field Installation Kit includes everything needed for installation — no additional parts required. Wiring harness, relay user guide, regulatory labels, and installation instructions included.
