Hughes Autoformer RSM50W Replacement Surge Module - Gen II 50A WiFi Surge Protectors

Hughes Autoformer RSM50W Replacement Surge Module — Gen II 50A WiFi Power Watchdog

OEM replacement surge protection module for the PWD50W, PWD50EPOW, and PWD50EPOHW Gen II units. Phillips screwdriver installation. Not compatible with Gen I units.

Restore Full Surge Protection Without Replacing the Whole Unit

The Hughes Autoformer RSM50W is the OEM replacement surge protection module for the Gen II 50A Power Watchdog WiFi surge protector series. Hughes's modular design philosophy is what makes this part exist — in the event of a major power surge, the module is engineered to absorb the hit instead of the main unit or your RV's electronics. Once a module has taken a significant surge, it should be replaced to restore full protection.

This module restores the full surge protection capability of your Gen II unit quickly and at a fraction of the cost of replacing the entire surge protector. Installation requires only a Phillips screwdriver and takes minutes.

đŸ›Ąī¸ Restores Full Surge Protection

Replaces a spent or damaged surge module to restore complete protection for your RV's electrical system and appliances

🔧 Screwdriver-Only Install

The only tool required is a Phillips screwdriver — no electrician needed, no special tools, no wiring expertise required

💰 Replace the Module, Not the Unit

Hughes's modular design means a surge hits the module — not your $200+ surge protector — so you only replace the part that took the damage

✅ OEM Hughes Part

Direct replacement from Hughes Autoformer — guaranteed to fit and function correctly in compatible Gen II PWD50-series units

đŸšĢ Gen II Only — Not Compatible with Gen I Units

This module is only for Gen II 50A WiFi units: PWD50W, PWD50EPOW, and PWD50EPOHW. It will not fit or function in Gen I Power Watchdog units. If you are unsure which generation you have, check the model number printed on your unit before ordering.

âš ī¸ Unplug the Unit Before Installation

Make sure the unit is fully disconnected from shore power before beginning installation. Do not attempt to swap the module while the unit is connected to any power source.
