Power Distribution and Surge Filter
TDCESF1 Power Distribution and Surge Filter Accessory
This accessory was designed to eliminate surge transients
and
– lines on a DC power source in order to pass EMC testing as a
stand-alone device. It will seldom if ever be needed for that purpose
because the Tritex II DC device will be connected to a power source that
does not pass this type of transient. The only time this could occur is if
the DC source is far away such as in an adjacent building and the
negative side is connected to ground locally and at its source. In general
it will not be needed to construct a system that will pass all transient
immunity tests for EMC compliance at the system level.
Its main use is for power conditioning and distribution, especially
where multiple Tritex II DC units have a common power supply and / or
shunt regulator. Features are as follows:

Dual input power connections for daisy-chain connection of main
power and logic power to multiple drives.

Additional ground “PE” distribution with dual terminals on
supply side

Blocking diode with removable bypass link

Inductor and additional bus capacitance to reduce ripple current at
power supply

Main power fuse

Side by side terminals for all four drive power cable conductors

Shunt blocking diode with removable bypass link

Dual terminals for daisy-chain connection of shunt to
multiple drives.

Quick connect main power terminals capable of handling 10 AWG
(4 mm
2
) wire

Din rail or flat panel mounting.
Configuration
J1 (six power terminals) and J2 (two signal terminals)
on the “left” side
connect to the power source. All have dual terminals for daisy-chain
connection of multiple devices. They are +Pwr, -Pwr, PE at J1 and Logic
Pwr+ at J2. Maximum current at +Pwr is 30A with current limit or fuse
protection at the source. Logic Pwr should be fused at 2A at its source,
which may be from the same power supply or a separate one.
J3 (six power terminals) on the “right” side connect to the Tritex II DC
as BusPwr (+),
PwrCom (-), Logic Pwr (+) and PE. The other two terminals are for
daisy-chain connection to the positive side of a shunt regulator. The
negative side of the shunt regulator connects to the open PwrCom (-)
terminal on the “left” side.
