DC Fail Relay with Window

The DC Fail Relay with Window is a monitoring device designed to detect and signal DC power supply failures in electrical systems. It continuously checks the voltage level of the DC supply and provides an immediate visual indication via a window when the voltage falls below a predefined threshold or experiences failure. This relay ensures the safety and reliability of critical systems by alerting operators to potential issues before they cause equipment malfunction or damage. It is commonly used in industries and applications where DC power is essential for operation, providing both audible and visual alerts for prompt action.
