LiteFuze LR-5000 5000 Watt Voltage Regulator with Transformer Step Up/Down 110V/220V - IEC Detachable Cord - Circuit Breaker. LiteFuze LR-5000 5000 Watt Voltage Regulator with Transformer Step Up/Down 110V/220V - IEC Detachable CordThe LiteFuze LR series 5000 watt Step Up/Step Down heavy duty voltage regulator with transformer is simple plug and play with auto input voltage detection. You do not need to worry about setting the input voltage with a manual switch, just connect it to any AC voltage outlet and its ready to go. It is also equipped with circuit breaker protection so you'll never need to replace fuses on overload. The voltage regulator function stabilizes the input voltage (90V-260V) and outputs both 110V & 220V from their corresponding outlets simultaneously. It also features the converting box technology which ensures lighter weight. The LR-3000 is compatible to operate on 50 Hz or 60 Hz. It is designed to convert single phase 110-120V to 220-240V or 220-240V to 110-120V. This CE certified transformer is safer with advanced side vents for ventilation. The efficiency factor of LR series voltage regulator transformers is 2.0, use this factor to determine the correct size voltage transformer for your electronics/appliances. Just multiply the efficiency factor times the max power(watt) rating of your product and then purchase a transformer of at least that size. LR series voltage regulator transformers are equipped with high grade copper coils which makes them energy efficient during voltage conversion
