TK-3402(U)/3402/3407 CIRCUIT DESCRIPTION 7. Power Supply There are fi ve 5V power supplies and three 3.3V power supplies: 50M, 50V, 50C, 50R, 50T, 33M, 33MS and 33B. 50M and 33M are always output while the power is on. 33MS is always output, but turns off when the power is turned off, to prevent malfunction of the MCU.
