Mascot Introduces its 4040 NiMH Professional Quality Battery Charger – for 6 to 40 NiMH Battery Cells

Microcontroller with smart charge logic maximises battery cells performance

Norwegian power design expert Mascot AS introduces its next-generation high-quality, high-performance NiMH battery charger, the new model 4040 NIMH. The 4040 uses a 3-stage charging profile with a microcontroller to maximise battery performance. The new charger has a robust -dV sensitivity detection and its top-off charge makes sure all cells are fully charged and balanced.

The safety protection features include error indication for reverse polarity, short circuit, charging battery packs with the wrong number of cells and safety timer run-out. The 4040 NiMH also features a single 3-colour LED indicator light for charge-, error- or standby status, and a wall-mount bracket is available.

By means of a Configurable Battery Charger (CBC) toolkit with a PC interface, it is possible to configure the chargers through their output cable with a range of custom charge parameter settings, including dV, dT/dt, 0 dV, timer, safety timer, dV threshold and temperature gradient adjustment. The CBC is also configurable in field. Other custom specifications are available on request, including special connectors, cords, logo print, housing / open frame / IP rating and certificates.

The 4040 NiMH is well suited for a wide variety of applications from medical to consumer; owners of the new charger will enjoy optimised uptime and turnaround for battery-powered equipment such as medical devices, telecom, energy storage and power-assisted E-Mobility products. The 4040 NiMH is medically certified according to EN 60601-1 ed. 3.2 and Home Healthcare EN 60601-1-11. It is also UL-approved. Five standard versions are initially available for charging batteries from 6-8 cell (8 A/13.6V) to 25-40 cells (1.8A/64.0V). Custom units available on request.
