LC302 Radio Control Speed Controller
Our new speed controller, the LC302, is even smaller than the LC301, and
is just 20 mm by 24 mm by 10 mm. However, it still manages a 3 amp
output, and takes a miserly 0.25 volt output drop. Battery voltage
can be anything from 4 volts to 18 volts. The LC302 is ideal for
smaller models where the LC301 would be a bit of a squeeze. The LC302
has a new speed control algorithm to give even better interference suppression,
and is available at the same price of £49.95. The LC301, which
has the option of directional lights, a second function output for LEDs
or relay, and/or manual control, will remain available, and is 39 mm by
18 mm by 10 mm.
-
Small size - The LC302 is probably
the smallest radio controlled speed controller available. At only
18 mm by 24 mm by 9 mm (wrapped in tape) or 20 mm by 24 mm by 10 mm as
supplied in its thick protective sleeve, the LC302 makes radio control
for HO or OO possible. The LC301, at 39 mm by 18 mm by 10 mm, in
not much bigger
-
High current capacity - Both the LC302
and the LC301 can supply up to 3 amps as standard, or 5 amps to order,
making them suitable for the full range of motors up to Gauge 1.
-
Low voltage drop - The LC302 and LC301
use a Zetex E-line power transistor with an extremely low voltage drop
combined with a relay for reversing. This results in a voltage drop of
only a quarter of a drop, well below the value obtainable using a solid
state bridge. Some competing controllers have voltage drops of just
over a volt - in that case one of your batteries is being carried for the
sole purpose of heating up the controller; none of the power reaches the
motor
-
Advanced interference rejection algorithm
- The LC302 and LC301 are microprocessor controlled and are programmed
to ignore signals from the receiver which are not valid radio control signals.
The signal is further filtered to ensure a smooth response for the motor
and excellent slow speed running. If the signal is lost - in a tunnel,
for example, or when the transmitter is switched off - the controller will
hold its speed and continue until it receives a signal again.
-
Works with cheaper AM equipment - The
powerful micro controller and advanced interference rejection algorithm
mean that more expensive FM equipment is unnecessary unless you require
more than six locomotives in operation at once.
-
Centre adjustment for different transmitters
- The micro controllers used in the LC302 and LC301 incorporate additional
circuitry to allow for an adjustment trimmer to tune the controller to
the mid point on the transmitter, so that 'off' on the transmitter matches
'off' on the model. This is a one off adjustment which only takes
30 seconds, and the units are supplied pre adjusted for Futaba transmitters.
Competing designs which use simpler micro controllers require the mid-point
to be set every time the unit operates by switching the transmitter on
before the receiver every time.
-
BEC circuit for receiver - The LC302
and LC301 incorporate a Battery Eliminator Circuit so that BEC and non-BEC
receivers can be used without an additional battery pack.
-
Low cost - All of the above for only
£49.95 (carriage
inclusive, UK), €79.75
(carriage inclusive, rest of Europe) and $84.95 (carriage inclusive, rest of
world).
