Product details

MFA Panel Mounted Speed Regulator

• Panel mounted speed controller unit with knob
• Allows you to smoothly vary output voltage from 0 to the input voltage
• Operating voltage between 6V and 15V
• Pulse width modulation for reduced power loss in the output
• Compact size easily mounts inside a project box or into an existing unit

Why use a speed regulator?

If you want to fine tune your output voltage to control your motors speed then this is for you. Compact design measuring 62mm by 41mm by 25mm and light 32g weight allows you to fit it in to even small projects or mount inside a project box to use on multiple projects. Transform your input voltage from 6-15V to between 0V to the input voltage (input power supply cannot be digital). Power width modulation reduces power loss in the transfer, provides a proportional output control and assists with maintaining torque.

Is it suitable for dimming LED lighting. What is the frequency of the PWM waveform.

Asked by: Lionel
We could not recommend this for use with LED lighting as it is not its intended use, as it has been designed for a specific range of motors and gearboxes. The manufacturer lists the frequency as follows; "Edge to edge frequency, min 1136 Hz, max 1250 Hz, average 1200 Hz."

Hi would this controller be suitable for a water pump (motor) 12v DC max 4 amp. (No mention on the motor of wattage, but I assume 48w)? 

Asked by: Dids
Unfortunately we cannot advise on individual usage. The specifications for the controller are posted on the listing, it would be for you to determine suitability for a particular task. It states 3A continuous load. It would be unwise to exceed this.

Can this be used to regulate the speed of this product on your website? MFA 6-15V Small 8768 rpm Motor Thanks

Asked by: jon110
This item has 3A Continuous but the motor selected as peak will draw around 4.8A I would advise yes if not running at max or to use a slightly higher value PWM

Hi does this speed controller need aan ac transformer to use in conjunction with a wired circuit that uses a 23A,12V,system that also uses 9 R14 C type batteries each at 1.5 volts

Asked by: Kev 1956
This item is designed to work on only DC voltages between 6V and 15V.

Can you use a voltage divider to power a motor lower that 6v?

Asked by: Chris
I am sorry but the item in question does not support use in your intended application.
