The TDA5051A stand-alone demo kit consists of two demo boards with AC power cords attached.  It can be ordered using part number OM13313. The PLM evaluation board can be used with a 230 VAC, 50 Hertz or a 120 VAC, 60 Hertz mains power line. It also may be used with a 0 to 48 VDC power line. If a galvanic isolated power transformer is used, it should be placed between the AC power line and the PLM evaluation board. A power line plug/cable is selected depending on the power line supply voltage and the safety enclosure used in the test bench setup. NXP provides an user manual, UM10422 and extended application support.
