AP-CHG-03 - Walter Universal Voltage Battery Charger Kit

Technical Overview

The Walter Battery Charger With Universal Plugs (SKU: AP-CHG-03) is a high-efficiency power management solution designed to support the Walter line of cordless industrial tools. Engineered for versatility and reliability, this charger accepts a wide input voltage range of 100V to 240V AC, making it suitable for operation on power grids worldwide without the need for external voltage converters. The unit utilizes advanced switching power supply topology to deliver a consistent and clean charging current to Lithium-Ion battery packs.

The charger features an intelligent battery management system (BMS) interface that monitors cell voltage and temperature during the charging cycle. This ensures that batteries are charged rapidly without compromising their cycle life or safety. The device is equipped with a multi-stage charging algorithm, typically transitioning from constant current (CC) to constant voltage (CV) modes to ensure a full saturation charge. Visual feedback is provided via integrated LED indicators, which display standby status, active charging, charge completion, and error faults (such as over-temperature or defective battery detection).

Physically, the AP-CHG-03 is housed in an impact-resistant casing suitable for MRO environments. The key differentiator of this model is the inclusion of a set of interchangeable plug adapters. These adapters easily snap into the main unit, allowing direct connection to North American (Type A/B), European (Type C/F), British (Type G), and Australian (Type I) outlets. This modularity simplifies logistics for international maintenance teams and ensures that Walter tools can be deployed globally with a single charging SKU.
