Sunrise Model Electronic Speed Controller PRO-100A Sunrise Model PRO-100A is a 100A brushless electronic speed controller designed for high-performance RC helicopters and airplanes, featuring smooth speed control and 2-6S LiPo support. It is known for its excellent throttle linearity, high-speed response, and built-in protections, often using a separate regulator for the Micro Controller Unit (MCU) to improve interference resistance. Sunrise Model Electronic Speed Controller PRO-100A Details: * Super fine and smooth touch of speed controlling, first-rate accurate linearity * Quick-respond speed of throttle * Separate voltage regulator IC for MCU (Micro Controller Unit) * High capability of anti-interference to decrease the possibility out of control * Low-voltage cut-off protection of battery * Blocked rotation protection * Throttle signal lose protection, can prolong the service life of ESC effectively * Compatible with a programming card to change parameters easily and conveniently * Safe power-on. The motor won’t start no matter which position the throttle stick is when battery connected. Key Specifications Continuous Current: 100A Battery Compatibility: 2-6S Li-XX (LiPo/Li-ion) or 6-16 Ni-MH/Ni-Cd cells BEC Output: Generally 5V-5.5V / 3A-6A, often switch-mode for reliable power Weight: Approximately 69g (including cables) or 29g (without cables) Dimensions: Approximately 50mm x 30mm
