Spektrum Marine 50A Brushless Speed Controller SPMX-1128

The Spektrum Marine 50A Brushless ESC, part number SPMX-1128, is a water-resistant electronic speed controller for marine radio-controlled models. It supports brushless motors and accepts 3–4S LiPo battery input, making it suitable for marine applications that require forward and reverse control. The ESC provides a maximum continuous current of 50A and a maximum burst current of 200A, with overload protection included.

An integrated switching BEC supplies 6V at 5A continuous current, with a peak rating of 5.5A. The unit is programmable and provides both forward and reverse operation. An IC3 connector is used for the input, while the motor output uses 4mm bullet connectors. The wiring is 12 AWG, and the ESC is supplied as a single Firma 50A Marine ESC.

Features

The water-resistant construction is intended for marine use, while the brushless design provides electronic control of a compatible brushless motor. The forward and reverse functions support manoeuvring in marine models, and overload protection helps manage demanding operating conditions. The compact housing measures 89 mm long, 28 mm wide and 14 mm high.
