Product information

Description

ZAMEL SZN-204 voltage loss indicator is designed for monitoring the presence of 230 V mains supply and signalling when supply disappears. Intended for mounting in electrical distribution panels, the device provides a clear indication of mains failure to support maintenance, safety checks and automation systems that rely on accurate detection of voltage loss. The compact module fits standard panel installation spaces and integrates with control circuits that need a reliable mains-failure input.

Advantages

The indicator continuously monitors 230 V supply and triggers an immediate signal when voltage is lost, reducing the time needed to detect outages. Its panel-mount design allows easy installation in distribution boards and switchgear, while compatibility with standard 230 V systems ensures broad applicability. The device offers straightforward operation without complex configuration and provides stable, repeatable performance for long-term monitoring tasks.

Suitable for

  • Electrical distribution boards and switchgear monitoring
  • Industrial and commercial electrical installations requiring mains-failure detection
  • Automation systems that need a reliable input for loss-of-voltage events
  • Maintenance and safety verification routines in facilities

Key specifications

  • Operating supply voltage: 230 V AC
  • Function: detection and signalling of mains voltage disappearance
  • Mounting: panel/distribution board installation
  • Output type: signal suitable for integration with control circuits and monitoring systems
  • Form factor: compact module for standard electrical panel spaces

How to use

Install the voltage loss indicator in the electrical panel according to applicable wiring and safety standards. Connect the device to the 230 V supply to be monitored and wire the signal output to the monitoring or control circuit that will receive the loss-of-voltage indication. After installation, verify correct operation by simulating a supply interruption to confirm the indicator signals as expected. Regular visual inspections and functional tests are recommended to ensure ongoing reliability.

Usage recommendations

Ensure installation and wiring are performed by qualified personnel following local regulations. Use the device only within its specified 230 V operating range and protect it from exposure to moisture and excessive temperature. Periodically test the indicator as part of routine maintenance to verify correct integration with automation and safety systems.
