YASONG SLA-1502 90dB Power Outage & Phase Loss Alarm Light, AC220V/380V, LED Strobe, IP54, Battery Backup
Choose the correct power configuration before ordering: single-phase AC220V, three-phase three-wire AC380V, or three-phase four-wire AC380V. Select the required warning light color separately.
Product Overview
The YASONG SLA-1502 is a power outage and phase loss alarm light designed to provide immediate audio and visual warning when an AC220V or AC380V power supply fails, loses a phase, has a broken wire, or is intentionally disconnected.
When a monitored power abnormality occurs, the unit automatically activates a 90dB buzzer and LED strobe light. Its built-in lithium battery provides backup power so the warning can continue after the main supply is lost. Select the correct voltage and wiring configuration before ordering.
- Automatic outage warning: responds to power failure, phase loss, broken wire, or intentional power cut-off
- Sound and light alert: combines a 90dB buzzer with high-intensity LED strobe flashing
- AC220V/380V options: available for single-phase and three-phase power systems
- IP54 enclosure: provides dust and water resistance for demanding environments
- Color options: available with a red, yellow, blue, or green warning light
Choose single-phase AC220V, three-phase three-wire AC380V, or three-phase four-wire AC380V, along with the required light color. Confirm the backup battery capacity and operating time before purchase if these details are critical to your application.
