Dual-Redundant Reliability for Critical Environments

The Leyard LND Series features dual-card and dual-power supply redundancy for
exceptional reliability. It is widely used in mission-critical environments including live
events, esports competitions, sports venues, command centers, high-end conference
rooms, auditoriums and concerts. Offering multiple pixel pitches with dual receiving
cards and dual power backup, the series meets high standards for both indoor and
outdoor applications.

Redundant Design

> Dual-Card Backup: During normal power-on operation, the main card outputs video signals while the backup card remains idle. In the event of a main card failure, the backup card takes over video output with nanosecond-level delay, enabling seamless switching.

> Dual-Power Backup: Supports overcurrent protection, short-circuit protection, PFC, current sharing and other functions.
