Smart Electronics 3.5A DC12V/24V PWM Motor Speed Regulator LED Dimmer Suitable for Brushed
and Brushless Motors
Basic Specifications
Input Voltage: DC 12V / 24V (Current varies by voltage)
Output Current:
DC12V: Maximum continuous current 3.5A
DC24V: Maximum continuous current 1.5A (Power-limited)
Suitable Loads: DC devices such as brushed motors, brushless motors, LED strips/fixtures, fans, water pumps, etc.
Functions & Features
Control Method: PWM (Pulse Width Modulation) – Adjusts duty cycle via knob for stepless speed/brightness control
Adjustment Range: 0%–100% (corresponding to speed/brightness from 0 to maximum)
Protection Features: Built-in overheat protection, short-circuit protection (Some models include self-resetting fuses)
Size & Mounting: Compact PCB board design with screw terminals (for easy wiring) and mounting holes
Important Notes
Supports DC input only; do not connect to 220V AC power;
Ensure voltage and current compatibility (e.g., load current must not exceed 1.5A at 24V);
The controller includes a heat sink; avoid prolonged full-load operation.
