Larson Electronics PWM Controller - Pulse Width Modulator - Buck & Boost - Dims LED lights - 135Hz

Pwm controller - pulse WIDTH modulator - buck & boost - dims LED lights - 135Hz. This pulse WIDTH modulator controller is designed to DIM any LED lights up to 72 watts. Basically, this a voltage regulator for LED lights drawing 12 amps or less. Pwm controllers are cpu controlled, digital alternatives to resistance based rheostats. This pwm controller has a rotating switch that enables the operator to control the brightness of the LED light. Thus, many operators will use this as a "dimmer" switch. This pwm can also be used to DIM our halogen lights, including the hl-85 and hul-18. Dimming halogen lights with a pwm is more efficient that using a standard rheostats. Rheostats create resistance, but always draw the same amount of amps. Thus, operators using halogen lights while dimming with a rheostat will draw down their battery capacity at the same rate as if they were running the light at full power. By using a pwm, the light will only draw the amps necessary to produce the dimmed output. If an operator wer...
