Logitech WCRC503 Manual

WCRC503 Wireless Power Receiver Module is the receiver part of a wireless power transceiver
module pair. A transceiver module pair consists of a transmitter module and a receiver module,
carefully tuned to be highly resonant with each other in order to accomplish efficient wireless
power transfer. The transmitter module transmits "resonant power" from the surface area of its
antenna (coil) defined by X & Y = power area and to a Z= height which is the distance from the
antenna surface. The receiver module, when positioned within the space defined by X,Y and Z,
receives the resonant power and performs the necessary conversions to supply to a load which is
typically the battery to be charged.
