Applications
The RCD-24-1.20 is designed to drive high-power LED strings in industrial luminaires, street lighting, and horticultural lighting systems where a stable 1.2A constant current is required from a 24V DC bus. Its 96% efficiency and wide 6V to 36V input range allow it to work directly from unregulated lead-acid or lithium battery packs as well as regulated 24V SMPS outputs without additional pre-regulation. EN and UL certifications make it suitable for LED retrofit modules and OEM light-engine designs targeting European and North American market compliance.

Frequently Asked Questions
What output current does the RCD-24-1.20 provide, and how does constant-current control protect LED strings?
The RCD-24-1.20 delivers a regulated 1.2A constant-current output, which prevents the thermal runaway phenomenon that occurs when LEDs are driven by a fixed voltage source. By clamping current at 1.2A regardless of LED forward-voltage variation over temperature, the module maintains consistent luminous flux and extends LED lifetime beyond 50,000 hours in typical operating conditions.
Over what input voltage range can the RCD-24-1.20 operate reliably, and which supply types does this cover?
The module accepts input voltages from 6V to 36V, covering 12V automotive and marine systems, 24V industrial control rails, and unregulated lead-acid batteries that may swing from 10V to 30V under load and charge cycles. This 30V input span eliminates the need for a pre-regulator in most mobile and industrial LED lighting installations.
How does the 96% efficiency of the RCD-24-1.20 compare to linear LED drivers for thermal management?
A linear current regulator dissipates the input-to-output voltage difference as heat; at 24V in and 20V LED string voltage the linear driver wastes 20% of input power as heat. The RCD-24-1.20's 96% switching efficiency means only 4% is lost, roughly ten times less heat than the linear equivalent, allowing smaller or even no heatsinking on the driver module itself at 1.2A output.
Which safety certifications does the RCD-24-1.20 carry, and how do these streamline product approval?
The RCD-24-1.20 holds EN (European Norm) and UL (Underwriters Laboratories) approvals, covering the major lighting safety standards required for CE marking in Europe and UL listing in North America. Incorporating a pre-certified driver module into an LED luminaire allows the fixture manufacturer to reference the module's existing test report, significantly reducing the time and cost of obtaining system-level safety approval for the end product.
