The Hobbywing SEPS 250A-24S Safety E-Power Switch is a professional high-voltage anti-spark electronic switchdesigned for industrial UAVs, heavy-lift drones, FPV systems, agricultural drones, and high-power electric propulsion platforms.
Engineered for demanding aerial applications, the SEPS 250A-24S provides safe power switching, stable current delivery, and reliable protection for high-voltage drone power systems.
High-Voltage 24S Power Compatibility
The SEPS 250A-24S supports high-voltage lithium polymer batteries up to 24S, with an input voltage range of 54–104.4V.
This makes it suitable for large UAV propulsion systems, heavy-lift drones, industrial multirotors, and professional aerial platforms using high-voltage battery configurations.
250A Continuous Current Capability
Designed for high-power applications, the Hobbywing SEPS 250A-24S supports up to 250A continuous current under good heat dissipation conditions.
This stable current capability helps ensure reliable power delivery to ESCs and propulsion systems during demanding UAV missions, heavy payload flights, and high-current operation.
Anti-Spark 4-Second Power-On Delay
The SEPS 250A-24S features anti-spark technology with a 4-second delayed power-on function.
After activation, power delivery starts after approximately 4 seconds, helping eliminate sparks and noise during start-up.
This protects battery connectors, ESCs, and electronic components, making the system safer and more reliable for professional drone use.
Safe Electronic Switching
The Hobbywing SEPS 250A-24S Safety E-Power Switch allows controlled connection and disconnection of the power circuit.
This helps reduce accidental power-up risks and improves safety during drone preparation, maintenance, battery connection, and field operation.
Its electronic switching system is designed for timely and reliable circuit control in professional UAV environments.
IP67 Waterproof & Dustproof Protection
The SEPS 250A-24S is built with IP67-rated protection, offering strong resistance against water, dust, and harsh operating environments.
This makes it suitable for outdoor UAV missions, agricultural drone operations, industrial inspection, field deployment, and heavy-duty professional use.
Industrial-Grade Reliability
Built with industrial-grade components, the Hobbywing SEPS 250A-24S is designed for long service life and stable operation.
The system has been validated through extensive reliability testing, including continuous power-on testing and flight testing, helping ensure safe and dependable performance in demanding UAV applications.
Compact & Robust Design
The SEPS 250A-24S uses a compact and robust housing with dimensions of 98 × 90 × 24 mm and a weight of 518.5 ±5 g.
Its 6AWG input and output wires are designed to support high-current power transmission, making the unit suitable for integration into professional high-voltage drone power systems.
