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.
The CAPTAIN RET411P,
pictured above, is a ideal replacement for hot mechanical Dumas controllers and
inferior units with sticky relays. With both proportional reverse and proportional forward
it is perfect for R/C scale boats, small subs, tanks and auxiliary robots functions. It
controls Dumas, Mabuchi 540, Astroflight 02 through 10 motors, gear reduced Astro 15 or 25
on 12VDC and most other motors rated 4.8 to 26 Volt DC at 12 genuine American Amperes
continuous duty or 30 Amperes starting surge. See the sidebar on Ampere ratings at ameramps.htm. The RET411P features the tried and true
circuit design of our venerable RET44 but with an increased voltage rating and
MOSFET ratings totaling 155 amps. An optional heatsink version is now available, specify
the RET411H.
The type RET512P is like a Novak controller that is rated to 26
volts and gives proportional reverse as well as proportional forward. Great for cars and
trucks, and for smaller performance boats or larger scale hulls. The RET512P
handles most '05 Hot Winds, Mabuchi 540, Astroflight ferrite motors operated at 14 cells
or less, and most other motors operated at 18 Amperes continuous duty or 50 Amperes
starting surge. Over 310 amps worth of MOSFETransistors. To order the heatsink version,
pictured above, ask for the RET512H.
Subs run nicely with the RET512 controllers.
The CAPTAIN type RET713P employs the highest rated MOSFETs available today to pack a
reversing 33 amp continuous duty 85 amp starting surge controller in a miniscule box.
MOSFET ratings total 480 amps. For your bigger toys like off-road trucks and dragsters and
up to 26 VDC! It will handle up to Astro40 marine cobalt. Like the others this unit can be
ordered as the RET713H with a heatsink. Or as the RET713P plate mount to
bolt on your machines metal heat dissipating frame to save space and expense. |
