3.1.2 Charging with the Power Box
A separate charging option is available for the QUBE CTW module which allows charging to be done
without the CasTemp Wireless Instrument. Both QUBE CTW module USB-A and USB-C variants can
be charged when using the appropriate CTW CHARGING CABLE with the QUBE CTW Power Box

Figure 12: Input and Output of Power Box
The power box requires a mains supply of 100-240VAC, 300mA mac, 50/60Hz. The input lead will
need to be prepared with the connector supplied in the kit. The output is identical to that of the
charging output on the CasTemp Wireless Instrument, meaning the same charging cable can be
used. Input and output leads are held in place using retention clips.
Ensure that connectors on both leads and on the power box are clean and undamaged before
connecting up.
