The OT2021A speed controller is a DC regulator designed for generator parts and automotive alternators. It is built on an FR4 PCB populated with electronic components. The unit accepts a supply voltage between 18 VDC and 36 VDC and delivers a continuous output current of 10 A, with a peak capacity of 20 A. This makes it suitable for maintaining stable motor speed in industrial generator sets.
In the power‑control market, such controllers are normally housed without a metal case, relying on board‑level protection. Typical operating temperature ranges from - 20 °C to 70 °C and the device conforms to standard IP20 enclosure protection. Standard efficiency for this class of controller is around 95 %. The controller’s dimensions are commonly about 100 mm × 60 mm × 30 mm, weighing roughly 0.5 kg.
Primary users are OEMs that assemble gensets, maintenance services that replace worn modules, and distributors supplying spare parts to power equipment manufacturers. Buyers should confirm the minimum order quantity and the preferred Incoterm with the supplier, as these details are not listed. The product is shipped from Datong, Shanxi, China, and can be packed in anti‑static bags within cardboard boxes.
