EST 1K maintains a constant output supply when voltage oscillates between 140 and 250 V AC. Allows 1000 AV load connection.
It features different protections to ensure output signal integrity: protections against overvoltage, overload, or short circuits . Also has a circuit braker on its rear panel. To avoid noises coming from ON/OFF switch, it also features a time delay circuit (3 or 6 sec.), after this time, normal operating mode starts automatically. A large display shows the information regarding devices status, like input, output and current voltage.
