Thank you for purchasing an MC401CR . The MC401CR is a high-frequency drive FET speed control developed for
model electric cars. It is compact and light weight competition speed control, and uses a simple digital setting system.
Applicable motors .UMBEROFTURNSISCRITERIA
Use the MC401CR with a motor with 10 turns or more.
*If a motor with a number of turns smaller than the
above is used, the heat protector and overcurrent
protection circuit may operate. The number of turns of
the motor is a criteria only. Depending on the running
conditions, the protection circuit may operate even if
the condition above is satisfied.
*The internal circuit of MC401CR is OK up to 10-turn
motors. On the other hand, the connectors for battery
and motor are general type that is often found at the
dealers. Therefore, to use high output power motor or
apply heavy load may result in overheating of the
connector section and melting the connection. If this
happen the connection will stick together. Please pay
special attention to avoid this matter.
Power supply
Nicd, NiMH battery 4~6 cells
(4.8~7.2V)
FEATURES
• SMD MOSFETs with smallest internal resistance for
minimal losses and maximum power
• Forward, reverse, and brake operations are all linear
• Reverse operation cancellation function
• PWM frequency is Performed by load adaptive
• Heat protector
• Low-voltage protection function
• Fuse 30A (Buttery reverse plotection / Overload plotection)
• Power left on alarm function
• Serial communication function
