Recently, Emerson Network Power introduced a new LDS100 series 100W LED power supply with a number of different product models to choose from, of which the H model is suitable for 120V-277V AC input voltage, and the U model is suitable for 100V-240V AC input. Voltage. The models introduced earlier can output DC voltage of 24V and DC current of 4.1A, meeting the requirements of Class 2 output, as well as the constant current output and constant voltage output modes, allowing customers to use only one product. Satisfy the requirements of different LED lighting systems, this will help reduce the inventory level of the manufacturer's customers. The operating range of constant voltage mode covers no-load to full-load conditions.

Take the LDS100-24-H03 model as an example, this product has a set current limit function, and its current limit value can be set through the interface according to IEC 60929 regulations. In other words, as long as the standard signal of 0 to 10V is used, the output current can be controlled and the brightness can be controlled. In addition, the current limit value can also be set by the adjustable resistor to facilitate the system design engineer to preset the relevant value.

All models of Emerson Network Power LDS100 series power supply have active power factor correction function with a rating of not less than 0.9. Therefore, in addition to complying with the EPA “Energy Star” regulations, it also complies with IEC 61000-3-2. Class C harmonic limits. The conversion efficiency of this series of power supplies is also extremely high. For example, the efficiency can be as high as 90% (typical) at a rated AC input voltage of 230V. This high efficiency can further reduce the user's electricity bill. When operating at rated power, the case's case temperature drops to -40 degrees Celsius or rises to 90 degrees Celsius without the need for a cooling fan to ensure that the power supply itself will operate within this wide temperature range. In addition, this series of power supply casing also has a version up to IP67 waterproof rating, in other words, immersed in shallow water will not cause damage to the power supply, so it is most suitable for outdoor equipment and equipment installed in indoor but bad working environment. With a compact size of 8.5 x 1.65 inches (215 x 42mm) and a thickness of 1.2 inches (30mm), this series of power supplies can be easily installed in a new generation of LED lighting systems with extremely limited space.

Emerson Network Power's LDS100 series power supplies not only comply with CISPR 15 standards regarding electromagnetic interference, but also comply with FCC section 15 (Part 15) regulations on conducted noise to ensure that these power supply systems do not appear Short circuit, overvoltage and overheating. In addition, the LDS100 series power supplies have been successfully tested to demonstrate that their anti-surge immunity complies with the IEC 61000-4-5 standard for Class 3 (Class U) and Class 4 (Class H) installations. Specifications test specification.

The LDS100 series power supplies meet the stringent requirements of several product safety standards, including product safety regulations for LED lighting systems, such as EN 61347-2-13 and UL 8750. In addition, this series of products also complies with the guidelines of CSA C22.2 No. 107.1 and CE LVD.

The LDS100 design platform has a high degree of flexibility so that customers can quickly make corresponding design revisions according to individual applications. Emerson Network Power's LDS100 series 100W LED power supply is available in volume.
