IS215WETAH1BB has 7 fuses on its surface. There are 4 transformers, 25 TP test points, and 6 wiring boards on the circuit board. The circuit board includes coil inductors, capacitors, resistors, relay components, integrated circuits, diodes, and jumper switches. There are over 100 voltage regulators on the circuit board. These components automatically adjust the resistance through a feedback loop (considering changes in load and input) while maintaining a constant output voltage. The voltage regulator is placed in a long wire form on the circuit board, parallel to three of the four edges.
