Epson PB-6509 M34PB AC Adapter 33V DC 1A for TM-U200D TM-U325D M119D M133A

The Epson PB-6509 is an original OEM AC adapter designed to power Epson's TM-U200 and TM-U325 series dot-matrix receipt printers. It accepts standard 120V AC input and steps it down to a regulated 33V DC output via a 4-pin Mini-DIN connector — the correct output voltage and connector type these printers require. The internal model designation on the rating plate is M34PB, and the unit was manufactured by Seiko Epson Corp. in Taiwan.

Applications

The Epson TM-U200 and TM-U325 are 40-column 9-pin dot-matrix receipt printers widely used in point-of-sale environments including retail, food service, and hospitality throughout the 1990s and 2000s. These printers require a specific 33V DC supply through a proprietary Mini-DIN connector — a standard wall adapter or universal supply will not substitute. The PB-6509 is the correct factory replacement for systems running either the two-station TM-U200 or the three-station TM-U325, covering both the parallel (PD) and serial (D) interface variants. Replacement OEM adapters for these legacy POS printers are increasingly difficult to source, making a genuine Epson unit a practical find for businesses still running TM-U200 or TM-U325 hardware.
