| Radio Control Reversing Electronic Throttle (RET series) |  |
|
This series of Reversing Electronic Throttles totally replace the mechanical throttle servos, cumbersome rheostats and switches that were formerly required to control DC Permanent Magnet motors in Radio/Control model boats, subs. The RET series has found use in ancilliary robot functions and G-scale trains. All of these units are fully proportional in reverse as well as forward from one R/C channel. For the Plate mount version they are a compact 1.8 X 1.97 X .82" and weigh about 2.5 ounces.
These units are optically isolated to eliminate noise "glitch" coupling and plug into your receiver like a servo but draw no receiver power. Available with connectors for Futaba "J" for FM or PCM, & Futaba "G" for older AM sets, Airtronics, Hitec, JR, Ace/Deans and Cannon/Deans. Compatible with many other radios as well.
Power MOSFET technology combines with moderate rate Pulse Width Modulation so you get smooth low speed operation, precise intermediate speeds and efficient full speed without the annoying "singing" of model car controllers. The solid state H-bridge design uses no relays, extra modules, nor are special heat sinks required. Unlike most hobby controllers with exposed transistors that can short out, these VANTEC units are fully enclosed and the critical MOSFETs that conduct your motor current are properly thermally mounted to a metal heat conducting plate or heatsink with special insulating washers. The case is electrically neutral.
COOLING: Small models like scale boats will not require any special attention for cooling. Closed hulls, like submarines, that contain other devices that run warm such as batteries should purchase the next better rated model. Larger applications with continuous motor loads at the controllers maximum ratings may require moderate cooling air or "P" plate versions may require mounting by their aluminum plate to additional heat dissipating surfaces. Because the case is electrically isolated you can mount the plate to your metal shelf, tank mechanics or robot frame when required. Measure your motor current under load with an inexpensive automobile amp meter. Larger models come with a heavy duty heat sink for dissapation purposes.
EASY TO USE: These controllers come with complete instructions and the single centering adjustment comes factory preset for your radio but can be readjusted. No awkward rate adjustment required. There are two wires for the motor battery and two wires to the motor. Plug it into your radio and you are ready to go!
ASSURANCE: The RET series is sold with a 21 day examination period. If you are not satisfied we will buy it back! TheRET has a limited one-year warranty based upon a nominal repair charge for units not tampered with or abused.
NOTES: A single Electronic Throttle may control several motors together if total current and voltage ratings are not exceeded; consider series as well as parallel motor connection. Dual motor systems with mechanically coupled shafts must be wired in series. TheRET411 is not for model cars. Paralleling Electronic Throttle servo inputs or use with mixers for differential twin screw or tank type steering is not recommended; use our RDFR series speed controls made for that purpose.
Warranty
Information:
One year warranty for repair on a fixed price basis according to the repair
deposit fee listed on the Vantec site's price
list at the time of submission to Vantec for repair, limited to units which
are not abused and one such repair per unit. All repairs must include proper
credit card information and have prior approval as evidenced by a Return Material
Authorization number or they will be returned to the sender.
