- High-voltage equipment monitoring systems
Procurement Notes
Verify the specific voltage rating against the target application circuit, as this model supports a wide input range from 30 to 120 VDC. Confirm that the required sound pressure level of 88 dB meets the acoustic environment specifications. Ensure the panel mounting hole dimensions align with the 41.8 mm diameter requirement. Check lead length availability if direct wiring is necessary without additional connectors.
Selection Notes
Select this component when a high-voltage piezo buzzer with an internal driver is required. It is suitable for applications needing a single-tone alert without external oscillation circuits. Consider the 88 dB output for environments requiring moderate audible alerts. Verify compatibility with the available control voltage within the 30-120 VDC range before finalizing the design.
Part Context
This part belongs to the Same Sky industrial-grade audio indicator series. These devices are engineered for durability in demanding environments. The series offers various voltage ratings and sound levels to accommodate different industrial signaling needs. The CEP-4411AC specifically addresses high-voltage DC applications.
Replacement Considerations
Check for parts with identical 88 dB SPL and 2.8 kHz frequency. Ensure replacement units support the same 30-120 VDC operating range and feature integrated driving circuits. Verify mechanical compatibility with the 41.8 mm panel cutout.
