TSC SP-MH241-0025 Replacement Power Supply
Overview
The SP-MH241-0025 is a genuine replacement power supply for TSC thermal label printers in the MH, MB, and ML series. If a printer in this family loses power delivery or the supply fails, this component restores full operational voltage to the printer controller and print head. Install it when you need to bring a printer back online without sourcing through lengthy OEM channels.
Compatibility
The SP-MH241-0025 is engineered as a direct replacement for the following TSC printer models and series: MH241, MH341, MH641, MB241, MB341, ML240, and ML340. Verify your specific model against the compatible device list before ordering — this supply is not a universal fit and will not work with printers outside this family (e.g., DA, TC, TE, TX, or T-series printers use different power architectures).
Installation Notes
Power supply replacement requires disconnecting the printer from mains power, removing the access panel, and unbolting the existing supply from its mounting bracket. Unplug the connector harness from the printer controller and the ribbon feeder. Install the new supply in reverse order, ensuring all connectors seat fully and the bracket bolts are snug. Do not operate the printer with loose power connections — improper seating can cause intermittent voltage dropout and print-quality failure. If you are not familiar with thermal printer internals, have a qualified technician perform the swap.
