LED Driver | Helvar LL1x10-42-E-CC

LED constant current driver 42W for pro luminaires

Helvar LL1x10-42-E-CC is a premium-grade solution for demanding lighting projects. This LED constant current driver delivers stable output for long LED lifetime. It also keeps energy losses low with efficiency up to 94%. The power factor reaches 0.98 at full load. This helps reduce reactive power in professional installations.

The driver works with a wide input range. It supports 198–264 VAC and also 176–280 VDC. This makes it flexible for modern systems. The unit is designed for Class I luminaires and requires protective earth connection.

LED constant current driver – key benefits

• 42 W output power for professional LED modules.
• Adjustable output current 120–350 mA via external resistor (Rset).
• Up to 94% efficiency and PF 0.98 at full load.
• Very low ripple <2%, compliant with IEEE 1789 recommendations.
• Built-in protection for short circuit and open circuit conditions.
• Long lifetime up to 100,000 h at tc = 65°C.

Adjustable output current for precise LED matching

This LED constant current driver lets you set the output current to match your LED module. The default current is 120 mA. You can increase it up to 350 mA using an external resistor. For best accuracy, use a low-tolerance resistor. If no resistor is connected, the driver stays at the default setting.

Low flicker performance and premium quality

Ripple stays below 2%, which helps reduce visible flicker. This supports comfortable light in offices, retail, and architectural spaces. The premium build also supports stable operation over time. It is a strong choice for professional, long-life installations.

Constant current LED power supply with smart protection

The driver includes protection against short circuit and open circuit. When an open circuit is detected, the output voltage is limited. This helps protect the system during abnormal conditions. Surge immunity is also tested, including up to 2 kV L-GND.

Applications

• Architectural and commercial luminaires.
• Professional LED modules requiring constant current control.
• Projects where low ripple and high efficiency matter.
