Phihong has released a 24 V, 8 A lead acid battery charger designed for power wheelchairs and mobility scooters with AGM or GEL batteries. Designated the DA200U-250A, the battery charger features a convenient USB output connector, consumer electronics control (CEC) wiring, and LED indicators that communicate five charging states: connected to AC power, 25%, 50%, 75% and 100%.
Rated for 100 to 240 VAC input and 24 VDC output, the lead acid battery charger offers better than 87% average efficiency based on Level V Energy Star requirements. It is compliant with several critical safety standards, including the Rehabilitation Engineering and Assistive Technology Society of North America’s (RESNA’s) WC-2:2009 American National Standard for Wheelchairs with Electrical Systems, which is based on the requirements and test methods that the International Standards Organization (ISO) defined for the power and control systems designed into electrically powered wheelchairs and scooters (ISO 7176-14:2008). The charger also meets Canadian Standards Association’s (CSA’s) C22.2 No. 107.2-01 standard, and the European Committee for Electromechanical Standardization’s EN 60335-1 and EN60335-2-29 standards. The battery charger is also certified to CE safety specifications.
The charger features built-in over-voltage, short-circuit and over-temperature protections, and measures 254 mm (10 in.) long × 120.5 mm (4.74 in.) wide × 185 mm (7.28 in.) high. Allowable operating temperatures for the charger span 0° C to 40° C, with up to 90% relative humidity. Pricing starts at $40 each.
