WES4.6-T is
Wonpro's Patented "Tandem" power strip, which allows a user to
daisy-chain as many WES4.6-T power strips in tandem as needed in order to provide as many outlets as required by an
application. This tandem chaining is made possible by adding Wonpro's patented WSR connector at the end of
WES4.6's. Wonpro Tandem Power Strips can be daisy-chained in two
ways:
(1)
Using Wonpro slim WSRP connector

Using Wonpro daisy chain cord WE-103, which can be 1 foot, 2 feet, 6
feet, 12 feet, 20 feet, or 50 feet long.
The flexibility of WE-103 allows this daisy chain of power strips to
be positioned in many different ways
to meet the user’s physical real estate requirements.
The above picture shows two tandem WES4.6_T’s chained together by a
1-foot WE-103. This simple configuration provides a user with
12 outlets. This tandem power strip chain is then configured with a
UK power cord. This enables it to get power from a Type G UK outlet.
It also shows two close-up pictures of the special connectors at
both ends of a tandem power bar. A Wonpro power cord is vertically slided into the end
connector of a WES4.6-T. Unlike an IEC connector, the WSP-WSR
connectors form a very tight connection and cannot be pulled apart horizontally.
The above picture shows a configuration with 6 tandem WES4.6_T power
strips daisy chained together using 2-foot daisy chain cord
WE-103. The 2-foot cords provide enough distance to allow all
WES4.6_T’s to be positioned side-by-side in the same orientation; i.e., the on/off and reset switches of the six WES4.6_T’s are all on
the same side. This configuration provides the user with 36 outlets. This tandem power strip chain is then configured with a Schuko power
cord. This enables it to get power from a Type E or Type F outlet used in Germany, France, Sweden, Continental Europe, etc.
There are two
possible chaining designs:
(1)
Serial Daisy Chain - Chosen
In this design the
Daisy Chaining limits the total system load to be the same as that
of an individual WES4.6_T power strip. Therefore,
it guarantees that the total system load of the entire tandem power
strip chain will never exceed the limit of the electrical outlet they connect to. Due to the important of overload
protection, this Serial Daisy Chain design was chosen – to guarantee that no matter how many WES4.6_T’s are daisy-chained in
tandem, the tandem power strip chain can never overload the source electrical outlet it connects to.
(2)
Parallel Star Chain - Rejected
In this design the
Star Chaining each power strip bypassing all the tandem power strips
in the middle and connects to the
power outlet directly. In this configuration, there is no safe
guard to prevent overloading the outlet and cause it to overheat, melt, short circuit and damage the expensive equipments
connected to all the Tandem power strips. Since overload protection is a very important safety requirement, this Parallel Star Chain
design was not chosen.
With the Serial Daisy Chain
design, if a Tandem power strip in the middle of the chain is turned
off, all the remaining "downstream"
power strips are all turned off at the same time. That is,
unlike the Parallel Star Chain design, the daisy chained Tandem
power strips are dependent on each other -- none of them is independent of each
other; i.e., none of them is "standalone" by itself. Wonpro
solves the need to turn off a Tandem power strip anywhere in the
chain by offering a new power strip
WES4.6-ST,
which has a on/off
Switch or each outlet on the power strip.
