Associated Equipment Series Multi-Battery Charger with a 6-amp (0-158V) DC output is the series charger workhorse, charging 1 to 60 cells from 0 to 6 amps. This charger features state-of -the-art, anti-spark delay timer protection that eliminates sparking by shutting off the voltage when the current is interrupted, also providing safety during hook-up, and this added safety feature provides greater protection when the voltage approaches 158 volts DC while charging 10 batteries. The charger's output current can also be smoothly adjusted over its full range with the front panel control, and other safety features include polarity protection for both operator and equipment safety, circuit breaker protection, and the inclusion of an isolated transformer. This unit also features a fully-adjustable charge rate and a heavy-duty design for safe operation and quality performance. This made-in-the-USA product can be mounted on a wall or bench and also includes nine (9) charging leads, a full-wave silicon rectifier, and a limited 1-year warranty. This model charger also features a 120V AC input (13A, 60Hz) and comes with easy-to-remove clamps, an ammeter (0-6A), 6.5' AC power cord, and 8' DC leads, measuring 16" H x 19" W x 16" D overall. A 1-year "parts and labor" warranty is included for all components.
