Wide range AC mains input (85 Ֆ 265 VAC) allows use of one charger anywhere in the world and eliminates the need to stock and service multiple models. Convection cooling eliminates the need for a cooling fan, thereby increasing reliability and eliminating the need for fan replacement/service. Օ Advanced, high frequency, switchmode design allows more efficient (90% typ), faster charging and optimal charging independent of battery type or condition. Protection of IP46 (NEMA4) allows reliable operation in harsh environments. Օ Power Factor of > 0.99 minimizes utility surcharges and optimizes the use of AC line power. Select from an extensive list of approved charge algorithms (default I1, I2, U, I3a) Օ The chargers can store 10 separate algorithms which can be selected to match the specific batteries in use, thereby eliminating the need for multiple models and resulting in lower operating costs. Lightweight and compact size allows on-board use and offers space advantages over ferro-resonant chargers in traditional off-board installations. > Օ Extensive safety features such as reverse polarity and short circuit protection ensure safe operation for both the operator and the charger itself. The Curtis Model 1621 high frequency battery chargers are portable and allow easy charging of industrial vehicle batteries from 24 VDC to 96 VDC using any standard outlet in the world. LEDs allow at-a-glance charge status determination. Օ Battery temperature monitoring available via an optional temperature sensor input allows more accurate measurement and charging. > Curtis Model 1621 battery chargers are ideal for use in material handling, airport, golf, aerial lift, sweeper/scrubber, utility, Light-On-Road and general industrial battery-powered vehicles. > CURTIS INSTRUMENTS, INC.
