# Technical data ## Technical Specifications * 32-bit ARM Cortex M4 MCU * Operating voltage 6 - 24V / 2 - 5S LiPo * Maximum continuous current 25A per ESC channel * Instantaneous maximum current 40A per ESC channel, actively limited * 600000 ERPM maximum rotation field speed (useage up to 500000 recommended) ### Hardware/Feature Specifications * Telemetry capability (voltage, current, temperature, rpm) * Over current protection (measures the current and reduces it to max 40A) * Over temperature protection (reduces the max power if hotter then 100°C) * [sinHybrid](https://blog.seidel-philipp.de/kiss-sinhybrid-sinwave-backemf-hybrid-commutation/) :: Sinwave/BackEMF Hybrid Commutation for smoother running. * [Dshot](https://blog.seidel-philipp.de/dshot-digital-esc-signal/) 2400 (Full resolution of 2000 steps takes only 6.5µs) * Supports all common Dshot commands like turtle mode, 3D mode and rotation direction change. * Expanded adaptive auto timing (3,25-30° advance on each commutation) * For Race Multi-copters (25A continuous also with weak cooling) * High max. RPM (500.000ERpm, 71.400Rpm with a 14Pole Motor) * Accurate RPM control (2000 steps using Dshot) * No additional capacitor needed for 2-5S * Very fast throttle response * Linear throttle response * Active freewheeling (low diode losses) * Regenerative braking * [Dshot](https://blog.seidel-philipp.de/dshot-digital-esc-signal/) 100-2400, Oneshot42, Oneshot125 and normal (25 – 500Hz) PWM auto detected. * Supports FrSky Sbus, Graupner SumD, TBS CROSSFIRE and Multiplex SRXL as well as the Telemetrys, S-Port, Graupner HOTT, TBS CROSSFIRE and Sensorbus --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://flyduino.gitbook.io/kiss-documentation/english-kiss-docu/kiss-esc-25a-4in1/technical-data.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
