FAQs

MaxPulse and MaxDim units are a new generation of aircraft components. 

 Both our light dimmers and our landing light controllers are STC’d for a multitude of aircraft. Our light dimmers revolutionize the dimming control of instrument panels and cabin lights and our landing light controllers give the operator various control settings for his/her landing light or taxi light. Items come with a manufacturer’s warranty.

Max/Mini/MicroDim FAQs

Are your dimmers FAA certified?

Our MaxDim and MiniDim line of dimmers are FAA STC/PMA approved for installation in certified aircraft. We have a very extensive approved model list for Part 23 aircraft.

We also offer an uncertified line of dimmers – the MicroDim. This unit works well for the experimental market and allows us to customize a dimmer for the specific needs a customer might have. We have developed many custom designs for various OEM applications

What kind of lighting can the MaxDim/MiniDim/MicroDim control?

Our dimmers are PWM (Pulse Width Modulated) and can control almost any type of lighting that uses a DC voltage of between 5V and 35VDC. Our dimmers are not voltage specific. We can easily control LED, Incandescent, and lighting that uses DC voltage scaled up to AC via an inverter such as Electroluminescent.

Will I need any additional parts or tools to complete the installation?

Our dimmers and our landing light controllers are very easy to install and come with all installation hardware, instructions, placards, and FAA required documents (for certified units). A drill guide is also included if you choose not to use an existing hole. You will need to supply the crimpers and a wrench to tighten the bushing nut to the panel.

Why do you offer two different bushing lengths on your MicroDim line?

We realize that all instrument panels are not the same. The panel thicknesses can vary and some panels have overlays. We decided the best way to address this issue is to offer two different exposed bushing lengths, the 6mm bushing for instrument panel thicknesses of 2.2mm or less and an 11mm bushing for panels greater than 2.2mm in thickness.

Do I need to retain the old heatsink and transistor that was originally installed in the aircraft?

No, our dimmers do not require any type of heatsink.

Without a heatsink do the dimmers get hot?

Due to the nature of the dimmer design and the fact that they are greater than 99% efficient, virtually no power is lost to heat. The dimmers run cool to touch.

Are these dimmers noisy?

No, all of our dimmers have successfully passed the rigorous DO-160 Part 21 EMI (Electromagnetic Interference) testing. This testing shows our units generate no noise.

Can I drive both LED and incandescent lights one the same dimmer output channel?

Yes, you can do this and both types of lighting will dim fine. You may notice that the dimming characteristics might be slightly different as the LED lights will brighten first with the incandescent lighting following close behind. This is due to the nature of the two types of lighting. With a dual channel dimmer, you will be able to separate the two by putting all incandescent on one channel and LED on the other.

Why do you offer dimmers that offer incandescent and/or LED lighting curves?

Incandescent and LED lighting react to PWM in different ways. For instance, the LEDs will be just visible when the first PWM pulse comes out of the dimmer, but the incandescent lighting will lag a bit as it needs a bit of time to build the necessary heat to illuminate. This is why some of our dimmers offer an LED curve on one channel and an incandescent curve on the other. This allows for a very uniform dimming experience.

I have LED lighting in my aircraft and am using my original rheostat. The adjustment from full dim to full bright is very narrow. Is this normal?

Yes, using the original style dimmer will not give you much control over your dimming. Dimming LED lighting works much better using a PWM dimmer. This allows much greater control over lighting settings.

Are your dimmers compatible with NVG requirements?

Yes, our LED lighting curve was originally developed for NVG applications and our equipment is successfully flying in many NVG aircraft.

MaxPulse/MicroPulse FAQs

Are your landing light controllers FAA certified?

Yes, we offer the 9200-000-A and 9200-000-B units that are FAA STC/PMA approved for most Part 23 aircraft. We also offer the uncertified MicroPulse, part number 9100-001-M.

What is the difference between the two certified units?

The units are basically identical with the exception of the connectors. The -A model has spade type connectors and the -B unit has ring terminal connectors.

Will your unit control LED landing lights?

Yes, it works very well with LED lamps. Lamps manufactured by Whelen, AeroLED, and many others are supported.

Do all of your units come with mounting hardware?

Yes, all mounting hardware is included with the exception of the wire needed for the install.

Is your unit easy to install?

We have been told by our customers that our unit is very easy to install.

What different settings are offered by your MaxPulse?

Please look at our documentation page to see all of the different settings available for control of your landing or taxi light.

Will this product enhance the safety of my flight?

Yes, it has been proven by multiple studies that a flashing light is much more visible to surrounding aircraft, both at night and in the daytime. By making your aircraft as visible as possible you are greatly increasing the safety of your flight. Fire-fighting aircraft are required to have this feature for that very reason.
