DC trap blocker filter for toroidal transformers toroids-fully populated PCB-v.3

Description

Here I'm offering you a bare PCB for DC Blocker - v.3. It is a successor of the very successful second version of the unit.
It retains some of the  previous board specifications:
Dimensions of PCB
: 88x94 mm.
PCB thickness: FR4 2 mm. Copper thickness: 70 um (2oz). Surface finish - Nickel Gold (ENIG).
The board is TWO-layer design which allows the current handling capabilities of the board to be doubled.
All current conducting traces are widened as much as possible which additional raise the max. handled current.
PCB has solder mask coating on top and bottom layer for best durability.
Silk screen with parts layout is placed on the top of the PCB.
But for the first time now the customer can chose the variant with
6 discrete diodes which increases the ability for DC blocking up to 2V.
The possible variant of DC Blocking voltages are given on schematic below:
DC Blocker is built with following parts:
- two
MASSIVE 47 000uF EPCOS capacitors (the bigger is capacitance, the higher are handled currents)
- Six high-power discrete (2V DC Blocking voltage) diodes or one bridge rectifier (1.4V DC Blocking voltage)
- In case one wants to use the variant with discrete diodes but to keep the lower DC blocking voltage one diodes section can be bypassed by a piece of thick wire, as shown on the gallery pictures.
- one 10W power resistor
- one WIMA MKS4 400VAC capacitor
- two MOLEX 3-terminal connectors for AC input/output
- one PCB for DC Blocker.
All parts used are freshly obtained from reliable sources (Mouser, Farnell, Digi-Key etc.).
