DC Fail Alarm Relays

We design and manufacture Microcontroller based DC Failure Relay to monitor the DC supply / station batteries voltage and DC Protection Fuses in Control & relay panels. When DC supply fails and need the attention of the operators in the substations, DC failure relay gives Indication & output contacts.

Upon detecting a DC failure, the relay triggers an alarm to alert operators and maintenance personnel. This ensures timely response to power interruptions or faults, preventing damage to sensitive equipment or processes that rely on stable DC power. Commonly used in industrial control systems, battery-powered systems, and backup power applications, this relay enhances the overall reliability and safety of the system.
