Product Overview

The Harmonai L-8 is a professional-grade 8-channel power sequencer equipped with a 1.2-inch color LCD smart display that shows real-time voltage, date/time, and channel on/off status. Its built-in clock chip enables scheduled power-on/off and countdown shutdown; each channel supports independent delay settings from 0 to 99 minutes 59 seconds for both startup and shutdown. It stores and recalls up to 10 scene configurations, automatically detects cascaded units for multi-device control, and integrates via RS232 serial port into central control systems for remote centralized management. Dedicated under-voltage and over-voltage detection alarms, plus circuit breaker protection against short circuits and overload, ensure robust safety. With a total rated power of 7200W and maximum per-channel output of 2860W, the L-8 delivers reliable power sequencing for audio, lighting, projection, and other equipment in large-scale venues such as conference halls, multi-function rooms, and training centers.

Recommended Applications

The L-8 power sequencer is widely used in large multimedia conference halls, multi-function rooms, training centers, multimedia classrooms, high-end villas, and smart home installations. Its 8 independent delay channels ensure safe, sequential power-up and power-down of audio, lighting, and projection equipment—effectively preventing damaging inrush current surges. Ten pre-programmed scene presets simplify complex device management with one-touch switching. RS232 integration and cascading capability meet the demands of large-scale deployments requiring centralized control.
