30W Constant Current LED Driver

Buy durable 30W Constant Current LED Driver from leading China manufacturer Starwell. It is specially designed for fixed lighting applications that do not require brightness adjustment. The driver operates in constant current mode, with the output current preset at factory (common options include 350mA/500mA/700mA/1050mA), with an accuracy control within ±5%. This ensures stable and consistent light flux of the LED lamps. It does not include any dimming interfaces (0-10V, PWM or resistance dimming are not supported), and the circuit is simple and reliable, effectively reducing the failure rate. It is suitable for cost-sensitive commercial or outdoor projects that do not require dimming.

In terms of electrical performance, the product has a conversion efficiency of over 87%, and the power factor correction is better than 0.92, significantly reducing reactive power loss and meeting green and energy-saving standards. It is equipped with a comprehensive protection circuit, including overload protection, short circuit protection, over-temperature protection, and output open-circuit protection. Once the fault is resolved, it automatically recovers to ensure the long-term safe operation of the driver and the lamps in harsh environments.

The shell is made of high-strength aluminum alloy profiles, filled with internal heat-conducting sealant. This design not only achieves excellent heat dissipation performance but also reaches the IP67 protection level - completely dust-proof and capable of short-term immersion in 1-meter water depth, unaffected by heavy rain, rinsing, or high humidity condensation environments. The compact body design is paired with waterproof cable connectors, making installation convenient and allowing for direct fixation on the lamp body or independent brackets.

This drive unit does not incorporate any dimming interfaces (such as 0-10V, PWM, DALI, etc.). It is purely used as a constant current switching power supply, simplifying the circuit structure and reducing the failure rate. It is particularly suitable for fixed brightness lighting projects that are cost-sensitive and do not require dimming. It is widely used in commercial lighting (such as downlights, grille lights), industrial high-gantry lights, parking lot lighting, retail display track lights, advertising light boxes, and outdoor spotlights, etc. The product has passed CE and RoHS certifications, and undergoes 100% full-load aging tests before leaving the factory. It is of reliable quality and is an ideal choice for 30W-level outdoor constant current drives.
