Two new NiMH models to versatile battery charger family

Mascot has extended its 3743 and 3546 range of versatile, high-performance Blueline charger models to include new NiMH versions. The two new models are configurable and employ smart logic to optimise battery performance, incorporating robust -dV sensitivity detection, low cell temperature at the end of fast charge. A top-off charge makes sure all cells are fully charged and balanced. The maximum output is 15W for the 3743 charger and 27W for the 3546 model.

The safety protection features incorporate error indication for short circuit, reverse polarity, charging battery packs with the wrong number of cells and safety timer run-out.

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

The new chargers are ideal for various medical and industrial applications to the consumer; users will appreciate optimised uptime and turnaround for battery-powered equipment. Both models are medically certified according to EN 60601-1 edition 3.1 and for home healthcare use according to EN 60601-1-11. They are also UL-approved according to the US medical standard and meet the latest US DoE and CEC efficiency requirements.

Currently available are five standard versions (3-6, 4-8, 5-10, 6-12, and 10-20 cells).
