Lundahl Transformer DIN unit, DIN-unit_kit

Transformer DIN unit, DIN_unit_kit

The purpose of the DIN unit set is to provide housing and a pre-printed PCB for easy mounting of a selected range of Lundahl transformers, in particular for splitting and line isolation. When assembled, the transformer is electrically connected through screw terminals. The unit can be snapped on to a DIN rail, or be mounted using screws.

The slide show below indicates the work flow when assembly the DIN unit. Detailed instructions regarding how individual transformers are wired can be found in DIN transformer unit data sheet.

Depending on which transformer you chose, you will need to configure jumper wires on the PCB to match the transformer and meet your needs.

Recommended work flow:
1. On the PCB, wire and solder the jumper wires (use insulated wires)
2. On the PCB, place and solder the screw terminals
3. On the PCB, place and solder the transformer
4. Test the assembled board with AC signal (dont use Ohmmeter/DC voltage as this might magnetize the transformers core)
5. Put down the PCB in the DIN base (lower black housing part) until it snaps in
6. Take the DIN cover (upper grey housing part) and turn cover hinge side to output side of the PCB
7. Place the DIN cover (upper grey housing part) on the base and press it until it snap in place
8. Connect wires to screw terminals in the same manner as in XLR connectors (1-GND, 2-Hot, 3-Cold)
