Progressive Dynamics | Replacement Converter Section | PD4635V | 35 Amp

Upgrade your RV's power system with the Progressive Dynamics Inteli-Power Converter/Charger, engineered to deliver smarter, more reliable battery charging that protects your batteries and extends their lifespan. Designed as a direct replacement for select older Parallax/Magnatek and WFCO converter sections, this Inteli-Power unit is a smart upgrade for any RV owner tired of cooked batteries and inconsistent shore power.

Charge Wizard 4-Stage Charging — The Real Difference

The big differentiator here is the built-in Charge Wizard 4-stage charging system. Instead of dumping a single steady voltage into your batteries the way older converters do, the Charge Wizard automatically cycles between four stages — bulk, absorption, float, and equalize — to optimize charging for your battery's current state. The result is:

• Faster, more efficient charging when batteries are low
• Safe, low-voltage maintenance when they're full
• Periodic equalization to prevent stratification and sulfation
• No more boiling off batteries during extended hookups or long-term storage

For boondockers, full-timers, and anyone who's lost batteries prematurely to an old converter, this is the upgrade that pays for itself.

Reliable Power, Easy Installation

The Inteli-Power delivers consistent, clean power to your RV's 12V system while intelligently managing the batteries in the background. Each package includes a durable metal enclosure designed as a drop-in replacement for select older converter sections, making installation straightforward.
