Depending on the model, power will either be supplied from the USB port, from an external power
adapter or from an internal switching supply. The different types are described below. Table 1 on page 5
shows which type of power supply is required for each converter model.
USB powered
These devices are powered directly from the USB port. No power supply is required for these converters.
Power Adapter
These devices are provided with an external power adapter in the package. The adapter supplied has a
UK, EU or USA plug depending on the country of sale and so may vary from the one shown below. The
low voltage connector is either a 3-pin terminal block connector or a barrel-type jack as shown below,
depending on the model. For more details, see Table 1 on page 5.
The low voltage cable should be connected to the power (or DC in) socket on the converter, and the AC
input plug should be connected to a power source before using the converter.
Always use the supplied adapter to power your ES-U-xxxx-x converter; damage will occur if an adapter
providing the wrong voltage is used.
Internal Switching Power Supply
The rack mountable (ES-U-xxxx-RM) devices require an AC input (100V ~ 240V, 47 – 63 Hz) for the
internal switching power supply. A power cable is supplied with the converter, and connects to the power
inlet socket on the rear panel. The cable has a UK, EU or USA plug depending on the country of sale and
so may vary from the one shown below.
