Step-Down Autotransformers, E-JET Series The E-JET step-down autotransformers allow the adjustment and operation of 110 V appliances connected to 230 V mains. Using autotransformers achieves an approx. 50% lower nominal rating compared to transformers with galvanically isolated windings. To ensure the output voltage to earth is not greater that the nominal output voltage, the output voltage (monitored electronically) is only switched when the safety plug is correctly inserted in the mains socket. Short-circuit protection by means of a fuse in the input circuitry Insulator for housing with carrying handle In accordance with VDE 0550 for protection class 1 Type Unloaded secondary voltage approx.

Carroll & Meynell
Rohs Verified
Portable Step-Down Auto Transformers CM series The CM series of autotransformers from Carroll & Meynell are a stepping down solution. These autotransformers are designed for stepping down UK mains voltage to a 0 V to 115 V supply for equipment designed for the US market. Features and Benefits: Protection from thermal overload Ingress protection to IP20 from glass reinforced polyester The input consists of mains cable with 3-pin 13A plug One US style 3-pin 15A/127V flush-mounted socket for the output Robust white enclosure Approvals 8888 Warning These units do NOT provide isolation from the mains. This series does not convert the UK 50Hz frequency to the US mains 60Hz frequency.
