从China供应商批量进口24w Dimmable Multi Current Led Driver

This 24W dimmable constant-current LED driver supports selectable output currents of 300mA, 450mA, 500mA, 650mA and 700mA via DIP switch, allowing one stock-keeping unit to serve multiple LED module configurations. Input range is 100-240VAC, with Class II double-insulated construction eliminating the need for an earth ground connection. The driver achieves up to 85% efficiency and relies on natural air convection through its plastic IP20 enclosure, restricting use to indoor dry locations. Dimming is achieved through either switch-dim or 1-10V DC analogue control, with a permanent memory function that restores last intensity after power interruption and soft-start behaviour to reduce eye discomfort.

The multi-current architecture suits LED lighting manufacturers who standardise on one driver platform across product families with varying LED string voltages and counts. Current accuracy is described as high, which in this context typically implies tight tolerance to prevent LED overcurrent that accelerates lumen depreciation. Hiccup-mode short-circuit protection limits stress during wiring faults, while overload protection guards against excessive load demand. The plastic case and absence of forced ventilation place thermal management burden on proper enclosure design in the luminaire; ambient temperature derating is not stated in the source data and should be confirmed directly.

Switch-dim operation uses push-button duration to distinguish on/off commands (50-500ms) from stepless dimming commands (exceeding 500ms hold), with direction reversal every second long push. Synchronisation across multiple drivers sharing a single switch is unlimited in quantity, enabling uniform control of large arrays without dedicated dimming bus infrastructure. The 0.3% to 100% dim range with claimed flicker-free output targets residential and hospitality applications where visual comfort is critical. Packaging is 100 pieces per carton with gross weight 20.0kg and dimensions 45.5 x 39.5 x 22cm, suggesting compact individual driver size suitable for downlight and panel light integration.

Shenzhen Longrich Energy Sources Technology Co., Ltd. is located at 2/F, 20th Building, Changxing Hi-Tech Industrial Park, Wanan Road, Shayi Villa, Shajing Town, Shenzhen 518104, Guangdong, China. The company sits within Shenzhen's extensive electronics manufacturing corridor, with proximity to component suppliers, testing laboratories, and Shenzhen Port for export logistics. The supplier carries an imported tier designation alongside harbour trust tier, indicating some level of platform verification, though the response rate is recorded at 0.00 with zero average response hours. This lack of response history means buyers should initiate direct contact early to assess communication reliability and technical support capability.

The company's focus, per this listing, is on dimmable constant-current LED drivers for indoor lighting applications. No information is provided about factory size, years in operation, annual turnover, employee count, or named customers. The product emphasis on multi-current flexibility and multiple dimming protocols suggests targeting of OEM lighting fixture manufacturers rather than retail consumers. Buyers should request company registration documents, quality system certification, and references from comparable European or North American clients if available. The Shajing Town address places the company in a district with substantial LED industry concentration, which generally supports shorter component sourcing lead times and competitive tooling costs.
