LED Driver Module AUNMAS 3W/2W 700mA PWM Dimming 5‑35V Input

Description

Product Overview

The AUNMAS LED driver module is engineered to deliver a precise 700 mA constant current, making it an ideal power solution for 3 W and 2 W LEDs commonly used in 3D printer lighting, hobbyist projects, and low‑voltage illumination systems. Constructed with a high‑efficiency chip and robust PCB layout, the module maintains low ripple and stable output across a wide input voltage range of 5 V to 35 V. This flexibility allows the driver to be paired with a variety of power supplies, from USB‑type adapters to dedicated DC sources, without sacrificing performance. The module features clearly labeled VIN+/VIN‑ and LED+/LED‑ terminals, simplifying wiring and reducing the risk of connection errors. Integrated protection circuitry guards against overload, short‑circuit, and over‑current conditions, extending the lifespan of both the driver and the connected LEDs. The compact form factor, measuring just 5.91 × 3.94 × 1.97 inches and weighing only 1.59 ounces, enables easy integration into tight spaces and custom enclosures.

Usage

Designed with versatility in mind, this driver excels in environments where precise brightness control and reliable power delivery are essential. In 3D printers, the module can be used to illuminate the build chamber, providing uniform lighting that enhances print monitoring and improves surface finish quality. Beyond printing, the driver is well‑suited for DIY lighting rigs, portable lanterns, and small‑scale display installations where PWM dimming enables smooth transitions and energy‑saving operation. Its wide input voltage tolerance means it can be powered directly from battery packs, solar panels, or regulated DC supplies, making it a popular choice for outdoor projects, educational kits, and prototype development. The module’s low power consumption and efficient conversion also contribute to reduced heat generation, allowing it to operate continuously without the need for additional cooling mechanisms.

FAQ

What type of LEDs can I connect to this driver?

The driver is optimized for 3 W and 2 W LEDs that operate within a forward voltage range of 2‑3 V. It can also handle series strings of multiple LEDs as long as the total forward voltage stays at least 2 V below the supplied input voltage.

How does PWM dimming work with this module?

PWM dimming is achieved by feeding a pulse‑width‑modulated signal to the driver’s control pin. A high‑level signal closes the output, while a low‑level signal opens it, allowing you to vary the duty cycle and thus control LED brightness smoothly.

Is the driver compatible with battery power?

Yes. The 5‑35 V input range accommodates common battery configurations, including 7.4 V Li‑ion packs, 12 V lead‑acid batteries, and even 24 V automotive supplies, making it suitable for portable and off‑grid projects.

What protection features are included?

The module incorporates overload protection to prevent excessive current draw, short‑circuit protection to guard against wiring errors, and over‑current protection that shuts down the output if the current exceeds safe limits.

Can I use this driver in a multi‑module setup?

Absolutely. Multiple drivers can be cascaded or operated in parallel, provided each module receives the appropriate input voltage and the total current demand does not exceed the capacity of your power source.
