Wisdom NWB-25A Fast Smart Charger for KL Series Lamps

The NWB-25A is a portable, smart (intelligent) charger specifically designed for Wisdom KL series lamps with LiIon batteries.

Recommended for KL8M, KL8MS, KL12M and KL12MS Wisdom cap lamps. Not suitable for use with the ATEX GII or ATEX M1 Wisdom KL lamps since these lamps need to be charged on the standard chargers to maintain the ATEX rating.

The charges uses the industry-standard and very robust 'keyway' charging pin, which is inserted into the lamp head and secured with a half turn.

Charging is indicated by a simple LED indicator; red for charging, flashing green for fully charged. The charger correctly conditions the lamp battery and automatically switches off at the end of the charge sequence, preventing over charging and allowing the battery to be topped up safely and at any time.

AC and DC input, allowing the charger to be used with the mains supply or - with the optional DC cable - from a 12V car/van accessory power point.
