Product Overview

The Harmonai L-16 is a professional-grade 16-channel power sequencer engineered for stage lighting, audio systems, conference rooms, and broadcast studios. It features 16 relay-controlled universal outlets plus 2 direct-pass universal outlets, supporting up to 6000W per channel and a total load capacity of 15,000W — ideal for high-power equipment clusters.

The unit implements intelligent sequential power-on / reverse-sequential power-off logic, with a default 1-second interval between channel activations to prevent inrush current surges on the mains supply. A PASS function button enables instant activation of all channels simultaneously for emergency use. A precision red LED voltmeter displays real-time input voltage, and the built-in switching power supply supports global AC 90–260V input (50–60Hz).

For safety, the L-16 integrates a triple-protection system: leakage current protection (30mA / ≤0.1s), 63A short-circuit protection, and overcurrent protection. Dual-pole (live + neutral) circuit breakers provide comprehensive electrical isolation and safety assurance.

Typical Applications

Stage & Lighting Shows: 16-channel sequential power cycling protects lighting gear from surge damage; high-power output supports multiple lighting rigs concurrently.

Audio System Integration: Zoned power delivery for amplifiers, processors, and mixers; reverse-sequential shutdown eliminates turn-off noise and protects sensitive components.

Conference Rooms / Multi-Function Halls: One-touch sequential startup for projectors, audio systems, and microphones; USB port powers DJ lighting directly.

Broadcast Studios / Recording Facilities: Precision sequencing safeguards critical equipment; accurate voltage monitoring ensures stable, clean power.

Temporary Large-Scale Events: Global AC 90–260V auto-adaptation makes it suitable for venues and regions worldwide.
