Iota Engineering ITS-30R 30 Amp AC Transfer Switch

The ITS-30R is a relay-based automatic transfer switch rated for 30A AC power systems, and provides switching between two separate AC power sources, such as auto-switching between generator and AC shore power. Use in conjuction with another ITS unit for additional power source switching. The ITS provides a 20-30 second delay before switching power. This allows the generator to stabilize before the power is delivered, avoiding damaging power fluctuations to your load.

The ITS-30R provides automatic power switching between two separate 120 volt AC input sources, including powercords, onboard generators, or onboard inverters. ITS will sense the presence of available supplies and automatically select the proper one. The ITS can be installed at the electrical entry of the on the line side of the main distribution panel, or it can installed on the load side of the panel between the panel and a sub panel, allowing switching for either entire electrical load or only designated circuits.

The ITS-30R is sometimes used as a ‘lock-out’ switch to prevent specific loads from being operated from designated supplies. Example: preventing a battery charger or air conditioner from running from an inverter, yet operating from generator or powercord.
