This replacement surge protection module is designed exclusively for PWD50-EPO Power Watchdog units operating in auto-shutoff mode. Rugged construction withstands the demands of frequent campsite use. A 4-second evaluation at power-on determines whether supply conditions are safe, followed by a 90-second delay if any fault is detected and cleared. This patented Autoformer design carries manufacturing from the USA.
