Extended operating range battery chargers optimized for wheelchairs

March 11, 2019 By Aimee Kalnoskas

battery chargersPhihong has announced its lineup of extended operating range battery chargers for power wheelchairs and mobility scooters. The complete line of products includes 2.5A, 3.5A and 8A chargers for different battery capacities.

The DA80U-240A-R and the DA64U-240A-R, rated 24V/3.5A and 24V/2.5A, respectively, work with AGM batteries and come in a compact, fan-less case measuring 6.14” x 3.11” x 1.77” weighing under two pounds. With an operating temperature range of -25ºC to +50ºC, they offer the widest range in the industry for comparable prices.

The DA200U-250A-R, rated 24V/8A, is capable of user-selectable charging of AGM or GEL batteries. The DA200U-250A-R offers an appealing fan-less case design and features a convenient built-in USB A receptacle for charging low-power electronics while charging your chair or scooter. The operating temperature ranges from -25º C to +40º C, which allows for charging in the most challenging environments.

Phihong’s DA series battery chargers accept worldwide AC input line voltages from 100V to 240V. All battery chargers are terminated with an XLR output cable and connector to work with a variety of manufacturer’s, power wheelchairs and mobility scooters. Phihong’s DA battery charger series also features LED indicators to indicate charge mode and full charge. Additionally, the DA200U-250A shows charge levels of 25%, 50%, 75%, and 100%, via green LED indicators.

All models feature an automatic 12-hour shut-off for battery protection, built-in over-voltage, short-circuit, and over-temperature protection; compliance with FCC and CE emissions and noise levels; and compliance to the U.S. Department of Energy’s (DOE’s) and California’s Energy Commission (CEC) requirements for battery charger efficiency.

The DA series battery chargers are compliant with several critical safety standards, including all relevant UL and CE safety specifications; 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 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.
