Ferro Resonant

Ferroresonant charging has been used for over 50 years because of its reliability and simplicity of design and repair.  Today, modern, controlled manufacturing practices and materials allow us to manufacture a ferro resonant charger that achieves high energy efficiency, 87% and power factor, 90%.   The design itself creates a fail-safe environment for your battery. If a component fails, the charger will fail to either a low output or no output condition.   Charging Technologies ferroresonant chargers are designed for a 4.5% finish rate at 2.6 VPC (+/- 1%) with a line variation of +6-/-10%.  The charge control interacts with the battery and the charger output ends when the battery reaches it’s perfect fully charged state DvDt/ DiDt.  The 301 and optional 303 controls are factory set for automatic equalize but a manual equalize may be performed at any time with the push of a button
