Pro Series 1/32 and HO Controller

Pro Series Electronic Controllers

The Pro Series of controllers are linear electronic controllers from OS3 capable of running all HO, 1/32 and some 1/24 cars depending on the style selected.  It requires only two wires to operate.  It is housed in the familiar Parma handle with a Parma trigger.  41" of super flexible 14ga wire outside the handle are terminated with color coded insulators over solid copper clips.  Each controller features a smooth trigger action covering a 40-Band wiping area.   Fuses are set in the wires for easy diagnosis and replacement.

Positive wired track where the White is Positive and the passenger side rail is ground. operate on 2 wire and 3 wire systems including home sets where only two wire connections are available.

The Pro Series is available in 2 styles, All Pro and Pro Lite with 3 ranges for each HO, Vintage and 1/32.

A brief breakdown of Controller functions follows:

HO ALL Pro - Adjustable Sensitivity, 100 ohm Brake, Coast and Choke. 3-Range Sensitivity switch, Brake/Off/Coast switch.

V ALL Pro - Adjustable Sensitivity, 100 ohm Brake, Coast and Choke. 3-Range Sensitivity switch, Brake/Off/Coast switch.

32 ALL Pro - Adjustable Sensitivity, Multi Option Brake and Choke. 3-Range Sensitivity switch, 3-Range Brake switch.

HO Pro Lite - Adjustable Sensitivity and 100 ohm Brake.

V Pro Lite - Adjustable Sensitivity and 100 ohm Brake.

32 Pro Lite - Adjustable Sensitivity, Choke and 5, 10 or 25 ohm Brake.

All Pro Series controllers feature the following:

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 Base (Pro)       Provides Easy-to-Read Labeling and ample spacing.  Rigid but soft to survive drops.  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.   An external Mini Automotive fuse is included to protect track wiring and Power Supplies but is not necessary to protect the controller.   The fuse can be easily checked and quickly replaced.  The electronic circuit board is hidden in the handle or protected by the plastic display panel.  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 inadvertantly 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   Resists wear while providing good electrical contact.  Use of a wiper board vice a "wiperless" pot removes the need for annoying switches that click everytime you pull or release the trigger.

Flexible Wiper Arm   Prevents the need for complicated and expensive hinges 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.   Use care in selecting the correct size fuse for your controller.   Please refer to the section "Protection" and "Why does your Fuse Blow" prior to selcting your fuse.

5 Amp (Brown) Standard Pro Series fuse.  Allows the fuse to blow before damaging protection circuitry in the commonly used MG PS10AD 10A Power Supplies.
7.5 Amp (Dark Red) Intended for tracks that are already protected or where Power Supplies can handle momentary shorts.

Pro Series fuses are for the Pro Series controllers only and will not work in any other OS3 controller.
