The Progressive Dynamics PD4645 Inteli Power 4600 Converter Charger is built as an upgrade or replacement for many factory installed RV power center converters. If you have an older Parallax, Magnetek, or WFCO converter that is hard on batteries or struggling to keep up with todays loads, the PD4645 gives you a modern, efficient 45 amp converter with smart charging built in.
This unit is part of the 4600 series replacement sections. It is designed to fit the lower converter compartment of compatible AC and DC distribution panels, so you keep your existing breaker and fuse layout while upgrading only the converter and charger electronics. That makes it a clean retrofit for many RVs without cutting into walls or replacing the entire power center.
The PD4645 includes the Progressive Dynamics Charge Wizard system, which constantly monitors the battery and automatically switches between four charging modes to speed up charging while protecting the battery from overcharging. In boost mode the converter quickly charges low batteries. Normal mode completes the charge, storage mode maintains a full battery at a lower voltage, and a periodic desulfation mode helps reduce stratification on flooded batteries. This four stage operation helps extend battery life and reduces watering needs compared to older single voltage converters.
With up to 45 amps of DC output, the PD4645 supplies solid 12 volt power to your RV lights, fans, pumps, controls, and accessories while also charging the house battery. The output is regulated to about 13.6 volts under normal load with low ripple and noise for sensitive electronics. Typical efficiency is over 80 percent, which keeps waste heat down and improves performance on shore power or generator.
To protect both the converter and your RV, the PD4645 includes multiple safety features. These include reverse battery protection, electronic current limiting, low and high AC input protection, automatic thermal shutdown, and a variable speed cooling fan that only runs as needed. If a battery is accidentally connected backwards, accessible fuses protect the converter.
The PD4645 is designed as a direct replacement section for several common 45 amp RV converters. It replaces many Parallax or Magnetek 6345, 7345, and 8345 units, as well as WFCO 8945 converters when installed with the included metal enclosure and hardware. The assembly is sized to fit an opening of roughly 12 inches wide by 4.75 inches high by 7.25 inches deep in compatible power centers.
If you are upgrading an older 45 amp converter that is hard on batteries or no longer holding stable voltage, the Progressive Dynamics PD4645 Inteli Power 4600 Converter Charger gives you a modern, smart charging replacement that drops into many existing RV power centers with minimal rework.
