LED power supply 40W 12V 3.34A PWM-40-12

LED power supply with PWM dimming function.

The PWM-40-12 LED power supply is a reliable source of constant voltage, designed to power LED lighting systems. This model offers an output power of 40W at a voltage of 12V and a current of 3.34A, making it an ideal solution for various lighting applications. Its compact dimensions (150x53x35mm) allow for easy integration even in limited spaces.

Construction and features

The power supply is characterized by high efficiency (up to 86%) and low power consumption in no-load mode (below 0.5W), which translates to energy savings. The housing made of durable plastic meets the IP67 standard, providing resistance to weather conditions and dust – an ideal solution for both indoor and outdoor applications. Additionally, the power supply has built-in protection against short circuit, overload, overvoltage and overheating, which guarantees safe and long-lasting operation.

Functionality and application

A key feature of this power supply is the PWM (Pulse Width Modulation) dimming function, which allows for smooth adjustment of LED brightness. This function is implemented in three ways: 0-10VDC, PWM and through resistance – giving great flexibility in configuring the lighting system. The active PFC (Power Factor Correction) circuit improves the power factor, minimizing energy losses and impact on the electrical network. The power supply has Class II insulation, which increases safety. Thanks to the wide input voltage range (90_{305VAC, 127}431VDC) it is compatible with various power systems. The operating temperature from -40 to +70°C allows it to be used in harsh environmental conditions.
