What is the advantage of this Rockler Router Speed Control?
Get the appropriate speed to match the router bit and application without investing in an expensive variable speed router This new and improved speed control gives you much more range in speed than the previous model. Set the rate all the way from 0 RPM to full speed varies depending on your router . Use on routers with brush-type motors up to 3 HP and 20 amps. Please Note Will not work with soft start routers.
Customer reviewsGood for small motors -- overheats easily
This router speed control stretches the truth a bit, but works reasonably well with modest power routers say 2 hp or for very intermittent use on higher power 3 hp machines. As it states in the product description, this speed control only works with brush type universal motors that do not have a built in soft-start or speed control circuit -- that is, it only works with single speed, instant start motors. However, the published power and current specs for this control are overstated. The internal solid state triac device bi-directional SCR that adjusts the motor speed is only rated at 25 amps maximum when mounted on an infinite heat sink, and the small metal back cover that mounts the triac in this controller is far from infinite. Thus the claimed 20 amp rating is only possible for only a few seconds before the control s internal circuitry overheats. The 26 amp rating printed on the control s front cover is total fiction. Left running for moderately long periods on a 2 hp router under load will cause the control to run excessively hot resulting in premature failure. When I used it on a higher power motor that drew 15 amps, the unit overheated and started smoking after about 15 seconds. Basically, this unit is good for about 10 amps with occasional short duration bursts to 15 amps. 20 amps is advertising hype and fiction. However, for small lower hp motors this speed control works well enough for the price. Note that while it provides a wide speed control range from near zero to full speed, the available motor torque and thus power will decrease as the speed control is turned down to slower speeds. Thus at slower speeds you can only work with very light loads.
