Drone Electronic Speed Controller (ESC) for Multirotor & UAVs

50–61.5 V DC (Up to 14S) 1 kW Continuous 3 kW Peak (60 s) Sensorless FOC CAN + PWM IP66

Overview

The Versa Drone Electronic Speed Controller (ESC) is a high-voltage, industrial-grade motor controller for multirotor and UAV platforms. It is designed to drive high-power BLDC drone motors from a 50–61.5 V DC (up to 14S Li-ion) bus, delivering 1 kW continuous and 3 kW peak (60 s) output power.

In terms of voltage class, current capability and mechanical envelope, it has been engineered to be compatible with widely used high-voltage drone ESCs such as the Hobbywing X8, so OEMs already using that class of controller can evaluate Versa as a potential replacement after their own fit and validation checks.

Using sensorless FOC, CAN communication and standard RC PWM input, this ESC suits both OEM drone manufacturers and advanced integrators who need robust performance, protection and diagnostics beyond hobby-level controllers.
