30A/60A 2-6S Bidirectional Adjustable Speed Self Starting Brushless ESC Features: This is a brushless electric regulator suitable for DIY modification, not a model aeroplane electric regulator. This electric regulator can be widely used for brushless power systems, such as water pumps, fans, knife grinders, hand grinders, electric hand drills and so on. This electric regulator is divided into two series and eight varieties Two Series: 30A 60A Each model has the following four subcategories: Bi-directional automatic start Model A: automatic start (It rotates at full speed after starting). Bi-directional automatic start Model B: Start and stop are controlled by a dial switch. (Turns to full speed after start) Bi-directional automatic start Model C: controls start stop and engine speed through a rotary switch. Bi-directional automatic start Model D: Stop and reverse rotation are controlled through a Dial switch, and speed is controlled by a knob. After starting the engine, the forward and reverse directions can be changed freely via a Dial switch. Special reminder: for numbers 1 and 2, as they rotate at full speed after starting, pay attention to heat dissipation. If necessary, forced cooling, such as air cooling and water cooling, can be done. Regarding the load: If the motor load is within 20A, an electrical setting of 30A can be selected. For motors with a load of less than 35A, an electrical setting of 60A can be selected. (Because the biggest fear of brushless electric regulators is heat generation, forced heat dissipation is necessary for long-term use). Specification: Bi-directional automatic start electric regulation 30A 60A. Operating voltage: 7-25.2V (2-6S Lipo) Maximum power: 30A: 500W 60A: 1000W Maximum speed: 224000 RPM (2-pole motor), 74000 RPM (6-pole motor), 40000 RPM (12-pole motor), 35000 RPM (14-pole motor). Temperature protection: Yes Locked rotor protection: Yes Over current protection: Yes Note: 1. Do not connect load devices that do not match the parameters of this electrical regulation. The positive and negative poles cannot be reversed, otherwise it will damage the electrical regulator. 2. If the customer modifies the heat dissipation by himself, please note that the components of the exposed circuit board must not be short-circuited and water must not enter, otherwise it may damage the electrical controller. Be careful when using it for the first time, as it is a power switch... Package Includes: 1* Bidirectional self-starting ESC Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
