Key Sections & Information:

1. Mechanical Dimensions & Pinouts (Multiple MTC-A variations): There are multiple pinout diagrams (MTC-A2, MTC-A3, MTC-A4, MTC-A5, MTC-A6, and MTC-A7). They describe the pin assignments for Single, Dual, and Triple output configurations.

- General Observations (Applies to most variations):
■ Pins 1, 2, and 3 are for AC Input (Line, Neutral).
■ Pin 2 is often "No Connect" in Dual and Triple output variations.
■ Several pins are designated as "No Connect".
■ The output pins are labelled as +DC OUT, -DC OUT, and +5V RTN (Return).
