This replacement surge protection module works only with PWD50-EPO Power Watchdog units in their auto-shutoff configuration. Heavy-duty construction stands up to regular campsite conditions. The system performs a 4-second power-on analysis to confirm supply conditions are safe, then engages a 90-second power-on delay after detecting and resolving any fault. Patented Autoformer engineering, made in the USA.
