Jeti Speed Controllers

The speed controllers are available in 2 main types; for brushed motors (DC commutator) and for brushless motors BLDC. Other factors in the selection of the controller are the voltage range of the drive batteries, current demands of the motor, and the method used to power the receiver and servos. Jeti speed controllers normally provide thermal protection, protection of the battery against low voltage (LVC), and over current protection. BEC (Battery Eliminator Circuit) controllers include an integrated circuit to provide a stabilised power supply to power the receiver and servos. Controllers that do not have BEC are marked OPTO, and require the use of a receiver battery (4 or 5 x NiXX), or an external BEC (Jeti MAX BEC is recommended for use with up to 12 cell NiXX, 3S LiPo, or 4S A123). OPTO controllers are designed to provide complete electrical isolation of the power supply from the radio system. OPTO controllers are recommended when BEC circuits are not sufficient for your needs because of a high servo count, the use of digital servos, or for models with high current consumption or high operating voltage.
