Product Details
Upgrade and restore your RV\'s electrical system with this Nationwide (OE Grade Direct Replacement) 45RU 45-Amp Power Converter and Charger module. Designed as a direct drop-in lower section replacement for outdated, noisy single-stage converters, this module smoothly converts 120V AC shore power into clean, stable 12V DC power to run your RV lights, slide-outs, water pump, and 12V appliances without voltage drops.
Equipped with an advanced 3-Stage Smart Charger (Bulk, Absorption, Float), this unit automatically adjusts output voltage between 13.2V and 14.0V to charge your house batteries up to 2X faster than legacy factory units while preventing overcharging—extending overall battery lifespan by up to 50%. It is fully compatible with Lead-Acid, AGM, and Gel battery banks.
Built with a rugged galvanized steel casing, oversized pure copper windings, and a smart, temperature-controlled cooling fan (≤45 dB), this converter delivers whisper-quiet performance and maximum heat dissipation. Features a built-in 6-layer protection system covering short circuit, reverse polarity, overload, over-temperature, over-voltage, and under-voltage conditions.
💡 PRO RV ELECTRICIAN TIP:
Before installing your new converter module, always disconnect both the 120V AC shore power cord AND the negative (-) cable from your 12V house battery bank! When making your connections, clean all chassis ground terminals with a wire brush. A bad or corroded ground connection is the #1 reason for voltage fluctuations, flickering lights, and premature converter fan burnout. Included Items:
- (1) 45RU 45-Amp Lower-Section Power Converter & Charger Module
- (1) Pre-Wired Harness Lead Assembly
- (1) Detailed Wiring & Installation Guide
