Item name: RC PWM Electronic Switch Relay Size: 41mm x 18mm x 11mm,With 30cm JR male plug cable Receiver-side PWM: 500-2500μs, 40-100Hz, 3V-5.5V Receiver Power Supply: 3.3V-12V, 21mA @5V Electronic Switch Maximum Pulse Current: 2400A Electronic Switch Continuous Current: 100A Load Maximum Voltage: 40V 100A High-Current Real-World Measurement Receiver and Switch Are Isolated (Non-Common Ground), Easy to Wire, and Safer to Use. Compared to relay contact sparking, electronic switches have a longer lifespan. MOS Overvoltage Protection (OVP) Soft-start switching with minimal inrush current Control Terminal: Supports 3.3V-12V Input with Reverse Polarity Protection for Worry-Free Operation Center-Off / Center-Hold Multi-Mode Operation Signal Loss Detection Mode Introduction Center-Off Mode: Switch ON at PWM pulse width Greater than 1750μs (e.g., 1751-2500μs). Switch OFF at PWM pulse width Less than 1550μs (e.g., 500-1549μs). Auto-disconnects on signal loss Center-Hold Mode with Override Disconnect: Switch ON at PWM pulse width Greater than 1750μs (e.g., 1751-2500μs). Switch OFF at PWM pulse width Less than 1250μs (e.g., 500-1249μs). Auto-disconnects on signal loss Color: As Shown Material: plastic Package Contents: 1 * Electronic Switch Relay
