Product Overview
ELIGHT constant current regulators are designed for powering lamp series circuits in public lighting systems, adhering to current directives. These regulators are known for their advanced technology, reliability, and ease of maintenance.

Principles of Operation
The ELIGHT CCR maintains a constant sinusoidal current in series circuits. It converts input AC voltage to DC, then to AC with PWM modulation, ensuring consistent lamp brightness regardless of aging, voltage drops, or temperature changes.

Key Features

• Input power factor at full load > 0.95
• Efficiency > 90%
• Energy savings with reduced luminous flux
• Reduced cable cross-section up to 100kVA
• 1% output current stabilization

Equipment Description
The system includes an input circuit breaker, rectifier, PWM IGBT inverter, transformer, control logic, parameter panel, and optional interface module.

Protections

• Regulator cut-off within 1 second for circuit interruptions or overcurrent
• Programmable restart delay
• Self-test system
