SCE048LD3PS1B

Alarms, Buzzers, And Sirens Overview

The SCE048LD3PS1B is an industrial-grade piezoelectric alarm from the Mallory Sonalert SCE series. It operates on a DC voltage range of 28 to 48 VDC with a current rating of 40 mA. The device produces a short pulse tone at a frequency of 3 kHz. It features screw terminal connections and is designed for panel mounting applications.

Alarms, Buzzers, And Sirens Feature Summary

• Generates a short pulse acoustic signal for alarm indication
• Utilizes internal driving circuitry for direct connection
• Supports wide DC input voltage range for industrial flexibility

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status alarms
• Control panel warning indicators
• Equipment fault detection systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific short pulse timing parameters against the official datasheet before integration, as this variant differs from continuous or chime models in the same series. Confirm that the 40 mA current draw is compatible with the host controller's output capabilities. Ensure the panel mount hole dimensions align with the physical specifications provided in the manufacturer documentation.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a distinct short pulse alert is required rather than a continuous tone. It is suitable for environments requiring cUL certification. Compare with SCE048LD3CTB for constant tone needs or SCE048SD3SD5B for double pulse variations within the same voltage class.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the SCE series of electronic audio indicators manufactured by Mallory Sonalert Products Inc. The series is characterized by piezoelectric technology and internal drive circuits, allowing for simple interface with standard logic or relay outputs without external oscillators.
