Pbm27a-210-mv--r Diagram !!link!! Jun 2026

The code (in earlier revisions, it appears as PBM27A-210(MU)-R ) refers to the main printed circuit board (PCB) used in the DEWALT DCB107 and DCB115 multi-voltage lithium‑ion battery chargers. These chargers are designed to work with slide‑pack batteries ranging from 10.8 V to 18 V (20 V Max), offering a convenient single‑charger solution for a variety of DEWALT cordless tools.

The DCB107/DCB115 charger operates as a standard with a smart charging controller. The PBM27A board can be divided into three main functional sections:

It is crucial to note that public repositories do not host this specific, proprietary schematic. Your best and safest course of action is to pursue official channels: pbm27a-210-mv--r diagram

Zone B: Control Logic & Signal Interface (Pins 1–12 / Micro-Connectors)

). This mode is vital for fail-open safety configurations in thermal or chemical pipelines. Internal Limit and Safety Microswitches The code (in earlier revisions, it appears as

A large electrolytic reservoir capacitor (typically 400V rated) smooths out high-frequency ripple voltage.

: An inline fuse (typically 2A) and a metal-oxide varistor (MOV) protect the internal components from massive power surges. The PBM27A board can be divided into three
