The Elite PRO model CBHF2-PFC high frequency battery charger is a truly universal charger. Output voltage, output current and charging algorithm can be adjusted using dip switches. It accepts AC input from 100 -240 VAC. This is a switch mode charger with high frequency transformers and IGBTs with digital controls. Both current and voltage output are finely controlled regardless of AC input. Low output ripple makes it ideal for sealed batteries. High efficiency ensures maximum charging power with low consumption. Output currents shown are bulk charging rates with no de-rating.
