The IceCap AC Skimmer Controller adds overflow protection, a feed timer, and a power-on delay to any AC (fixed-speed) protein skimmer or waste collector — features usually only found on DC-controlled models. A float switch shuts the skimmer down if water rises to overflow level. Protects against: skimmer cup overflow via float switch sensor Feed timer: 10, 30, or 60-minute pause options Power-on delay: 5 minutes, preventing immediate restart (and possible overflow) after a power outage Rating: single grounded outlet, up to 10 amps, 100-240VAC 50/60Hz Dimensions: 3.125in x 5.375in x 1.125in controller body; 6ft float switch cord, 7in pump outlet cord Warranty: 1-year limited Note: this is a controller only — it requires a protein skimmer and/or waste collection container (sold separately). For indoor household use only.Compatible with: AC protein skimmers and waste collectors up to 10 amps.
