Progressive Dynamics REL 90A 4500 Series Inteli-Power Converter Section PD4590CSV

Restore your Progressive Dynamics RV Power Control Center to full operation with the Progressive Dynamics PD4590CSV 90-Amp Replacement Converter Section. This drop-in repair part replaces the converter charger section in any PD4590-series 4500 Power Control Center — restoring full 90-amp Inteli-Power operation with built-in Charge Wizard, lithium/lead-acid compatibility, and the full protection suite, without replacing the entire distribution panel.

Drop-In Replacement — Saves Time and Cost vs. Full Panel Replacement

If your Progressive Dynamics 4500 Series Power Control Center has a failed converter section but the distribution panel itself is fine, this is the right repair part. Rather than tearing out the entire all-in-one panel and rewiring from scratch, the PD4590CSV slides into place — restoring full 90-amp converter operation with significantly less labor and cost than a complete panel replacement.

The PD4590CSV is a direct drop-in replacement for any PD4590-series converter section, including:

• PD4590, PD4590K18LR, PD4590K18LS2, PD4590K18LS8
• PD4590K18LS8V, PD4590K18LS9, PD4590K18NS2B
• PD4590LICSV, PD4590LIK18LS8, PD4590TB, PD4590V

Lithium AND Lead-Acid Compatible

One of the standout features of the current-generation PD4590CSV: the Lithium/Lead-Acid switch. The converter automatically tailors charging behavior to your battery chemistry — so if you replaced your lead-acid batteries with lithium since the original install, this replacement section is ready without needing a separate purchase.

Intelligent Charge Wizard 4-Stage Charging

The built-in Charge Wizard technology automatically manages battery charging through four distinct stages:

• Boost (14.4V) — high-output charging for depleted batteries
• Normal (13.6V) — sustained charging as charge approaches full
• Storage (13.2V) — maintenance charging that prevents overcharging during long stays
• Equalization (14.4V) — periodic equalization to maximize capacity and life

Built-In Protections

The PD4590CSV includes the same comprehensive protection suite as the full power control center:

• Reverse battery protection
• Electronic current limiting
• High and low AC input protection
• Automatic thermal protection
• Intelligent variable-speed cooling fan
