Helvar is a renowned Finnish company that manufactures components for lighting systems, specializing in modern illumination control solutions. The manufacturer’s offerings include high-quality LED drivers, constant current and constant voltage models.

Helvar drivers are known for their high efficiency (up to 96%), reliability, and compatibility with DALI control systems (selected models). They are used in both interior and architectural lighting, enabling precise brightness control. Additionally, Helvar products are used in offices, schools, hospitals, shopping centers, and public buildings, where energy efficiency, maintenance-free operation, and the ability to remotely control or program lighting arrangements are important.

The two most popular series of drivers are LL and LC. The LL series consists of linear drivers in metal housings. Within the series, it is important to distinguish between constant current (CC) and constant voltage (CV) versions. They feature a compact design and are compatible with control protocols such as DALI-2, TouchDim, and Switch-Control. The LC series includes compact devices in plastic housings. They are also available in CC and CV versions, designed with limited mounting space in mind, e.g., in lamp housings, recessed and decorative fixtures, and track lighting systems.

Helvar drivers are adapted for typical mains voltages (198…264V AC) and are equipped with a range of protections overload (OLP), short-circuit (SCP), thermal (OTP), and overvoltage (OVP).
