Safeguard your full-featured Class A motorhome or large RV with this hardwired 50-amp surge and voltage regulator. The always-on microprocessor continuously monitors 120/240V shore power, instantly disconnecting if voltage falls below 104V or exceeds 132V to prevent equipment damage and system failure.

Built-in time delays protect air-conditioning compressors during power cycling, while five layers of surge defence guard against transients in all configurations. Dual-voltage monitoring ensures both legs of your 240-volt service remain within safe operating parameters.
