1.1.2
Power section
The power section involves the power supply voltage (CN1, pins 4 and 5 for VCC, pin 3 for GND), load
connection (a load can be connected between pins CN1.1 and CN1.3 or CN1.2, and CN1.3; both output pins
are connected to the single output channel as shown in
) and electromagnetic
compatibility (EMC) protection.

For EMC:
•
transient voltage suppressor (TR1), enabled by closing J3, is placed between VCC and
GND tracks to protect the
against surge discharge on the supply rail path up to ±1 kV/2 Ω
coupling;
•
in the common mode surge testing, two single-layer capacitors (C1 and C2 - not included) must be soldered
at the predisposed locations;
•
output stages do not require additional EMC protections with respect to the IEC61000-4-2,
IEC61000-4-3, IEC61000-4-4, IEC61000-4-5, IEC61000-4-8 standards.
