Pro Series 1/32 and HO Controllers

Pro Series Electronic Controllers









The Pro Series of controllers are linear electronic controllers from OS3 capable of running either HO or 1/32 cars.  It requires only two wires to operate and is housed in a NEW OS3 handle with an OS3 rounded edge trigger.   Super flexible wires are available in multiple color options and are terminated with color coded insulators over solid copper/steel clips.   Each controller features a smooth trigger action.

Designed for standard Positive Wired Tracks where the White Track Post is Positive.
It will operate on 2 wire and 3 wire systems including home sets where only two wire connections are available.
It can run on any voltage from 6V to 24V but runs best between 10-14V for 1/32 and 12-20V for HO.

The Pro Series is available in 3 styles, ALL Pro and Pro Lite (32 Only) and Lite.

A brief breakdown of Controller functions:

HO ALL Pro - Adjustable Sensitivity with 3-Range Switch, Coast, Choke, Adjustable 100 ohm Brakes, Brake/Off/Coast Switch and a Full Power Kill Switch

HO ALL Pro ELITE - WIPERLESS Version with Adjustable Sensitivity with 3-Range Switch, Coast, Choke, Adjustable 100 ohm Brakes, Brake/Off/Coast Switch and a Full Power Kill Switch

32 ALL Pro - Adjustable Sensitivity with 3-Range Switch, Adjustable Brakes with 3-Range Switch and Choke.

32 Pro Lite - Adjustable Sensitivity, Choke, and Adjustable 25 ohm Brakes.

HO Lite - Adjustable Sensitivity and On/Off Brakes.

32 Lite - Adjustable Sensitivity and On/Off Brakes.

All Pro Series controllers feature the following:

OS3 Handle New Handle designed by OS3 to match the grip and feel of a Parma handle while allowing more internal room and a better mounting system.   The two sides grip together with a positive positioning system that makes assembly a snap.   No requirement to align the sides before tightening the screws or worrying about the sharp edges from a worn mold.   Available in 6 colors, Red, Blue, Yellow, Clear, Black and Purple.   Great for matching the standard lane colors of a 4 lane track.

OS3 Trigger Super strong rounded edge Nylon trigger.   Similar in shape to the Parma trigger but a lot more comfortable on your finger.

Super Flexible Wire Highly flexible silicon coated wires are used on all controller.   14ga for ALL Pros and Pro Lites and 16ga for Lites.   They are available in many color options.

Compact Design Transistor-in-the-Handle design allows the controller to be light and compact while also reducing the sharp edges and cumbersome weight associated with Transistor-on-the-Wires designs.

Plastic/Fiberglass Base (Pro) Provides Easy-to-Read Labeling and ample spacing.   Curved for easy holding.

Pivot Rivet Redesigned rivet removes the slop in the bushing and eliminates the need for bearings.   It also locks into the frame to prevent the trigger from drifting in position.

Protected Circuitry The main transistor is internally protected from short circuits (not available on the Lite controllers).   An external Mini Automotive fuse is included to protect track wiring and Power Supplies but is not necessary to protect the controller.   The fuse is conveniently tucked into the top of the controller where it can be easily checked, quickly replaced and not accidentally dislodged.   The electronic circuit board is twice as thick as others on the market and extremely robust.   This prevents a drop from cracking the circuit board and damaging the controller.   The All Pro switches are also positioned so that they can't be inadvertently switched when laying the controller down.   The controller can be laid down anywhere without risk of having the circuitry contact the track and cause damage to the controller.

Nickel-Plated Board (Wiper Board versions only) 40 Bands for fine control.   Resists wear while providing good electrical contact.

Flexible Wiper Arm (Wiper Board versions only) Prevents the need for complicated and expensive hinges or bearings while performing the same function of maintaining positive contact with minimal pressure to the wiping surface.

Aluminum Frame Redesigned frame serves as a heatsink and houses all components reducing overall weight.





Pro Series Fuses


Pro Series Fuses are for the protection of the track and Power Supply.   Please refer to the section "Protection" and "Why does your Fuse Blow".

5 Amp (Brown) Standard Pro Series fuse.  Allows the fuse to blow before damaging protection circuitry in 10A and greater Power Supplies including the commonly used MG PS10AD.   Pro Series fuses are for the Pro Series controllers only and will not work in any other OS3 controller.
