30A DC 1224V PWM LED Dimmer Knob Controller, Metal Housing, Stepless Dimming for 5050 2835 COB Strip

30A DC1224V Single Color LED Dimmer HL034 Overview A power PWM dimmer designed for constantvoltage single color LED lighting. The HL034 delivers stepless dimming from 0 to 100 percent using a manual rotary knob. Housed in a metal shell with no PC cover, this controller offers durable construction and efficient thermal performance for demanding LED strip and module applications. Key benefits output capacity: Supports up to 30A output current, enabling long runs or multiple 5050, 2835, or COB single color LED strips from a single controller. Smooth, precise control: Stepless potentiometer provides continuous dimming for flicker transitions and fine brightness adjustment. Robust construction: Iron shell metal housing improves heat dissipation and mechanical protection, extending service life in indoor and semiexposed installations. Simple operation: Onechannel rotary on off knob provides intuitive manual control without programming or complex setup. Wide compatibility: Works with any lowvoltage constantvoltage single color LED lamps and strips operating at DC 12 to 24 V.

Retail and display lighting: Adjust single color strips for product displays and signage to achieve consistent brightness and visual emphasis. Event and stage setups: Provide reliable, current control for longer LED runs used in temporary or semipermanent installations. Why choose this dimmer The HL034 balances power and simplicity. Its 30A capacity lets you run larger continuous sections of single color LED strips without adding multiple controllers. The metal housing helps manage heat in compact installations, while the rotary knob gives immediate tactile control suitable for everyday use by installers, designers, and end users. What to check before installation Ensure your LED supply is a DC constantvoltage source within 12 to 24 V. Confirm total LED load does not exceed 30 A or the calculated wattage for the selected supply voltage. Provide adequate ventilation around the metal housing if used near the upper operating temperature limit. This dimmer is a singlechannel solution for users who need reliable, current manual control of single color LED lighting with a durable metal housing and smooth stepless dimming.
