About this product

WCM-500 is TZBOT’s wireless charging module for AGV robots, using an adjustable 12–30 V, 8–15 A output and a nominal 20 ±10 mm charging gap. Its public gallery shows the transmitting and receiving equipment with a separate power unit. The manufacturer’s 500 W statement and adjustable electrical limits are retained as separately qualified claims; a simultaneous 500 W operating point is not established. The quoted dimensions and approximate mass are not explicitly assigned to the entire pictured equipment set. Cover image: Manufacturer exact-model image.
