The Sanwa BL-SIGMA controller is an electronic speed controller by SANWA, designed for use with brushed motors (over 12T). Works best with 1:10, 1:12 and 1:14 models of cars, powered by brushed electric motors (also for "Crawlers"), and thanks to the protection against moisture - in motor boats and other vessels.
The modern design of current connections and the highest quality of components used to assemble the regulator allowed to significantly reduce the weight and size of the device, which now fits into a small casing with dimensions of 32x36.5x18 mm, so far found only in regulators for a much "lower" class of motors. The heat sink embedded in the housing is responsible for efficient heat dissipation during operation, while the thick 16AWG wires in a soft silicone sheath ensure almost lossless voltage transfer from the battery to the engine, with a temperature tolerance of up to 200 C. Strong BEC system (6V / 3A) ensures smooth operation of even very strong servos based on metal gears, as well as all other connected devices (such as lights or sound modules). The regulator is also compatible with servos operating in SHR mode.
The controller has built-in systems protecting the controller against overheating and current surges, as well as protection against excessive discharge of LiPo and LiFe batteries.
The controller works with NiMH (7.2V), LiPo (7.4V) and LiFe (6.6V) batteries and brush motors max. class 600 (12T or more)
The ON-OFF switch is led out on the cable (and secured in a waterproof silicone sheath), thanks to which it is possible to "expose" it to the outside of the model's body or the ship's side.
The system of jumper switches facilitates quick setting of the regulator in terms of the operating mode and the type of battery used:
NORMAL mode: the regulator will work in the "Gas / Brake / Reverse" mode RACE mode: the regulator will work in the "Gas / Brake" mode CRAWLER mode: the regulator will work in "Throttle / Reverse" mode (only for slow running crawlers!)
Warning! Do not use the CRAWLER mode for cars other than the "Crawler" because it does not have a brake function - in a situation when the model is running fast forward, and reverse gear is turned on, the differentials or other mechanical components of the model drive may damage.
Features of the BL-SIGMA Speed Controller:
Size: 36.5 x 32 x 18mm Weight: 39 g Compatible motors: Brushed, class max. 600, 12T or more Compatible batteries: LiPo 2s (7.4V), NiMH 6s (7.2V), LiFe 2s (6.6V) BEC: 6.0V 3A Maximum supported current: 60A (temporarily up to max. 360A) when driving forward / 30A (temporarily up to max. 180A) when driving in reverse Internal resistance: 0.001Ohm in forward gear, 0.002Ohm in reverse Connector for connection to the battery: TAMIYA standard
Basic / temporary resistance to dust, dirt and moisture - the regulator should not be exposed to prolonged contact with water and moisture.
