Power section

The power section involves the power supply voltage (CN1, pin 2 and 3 for V
(between CN1 pins 1-4 and CN1 pins 5-4) and electromagnetic compatibility (EMC) protection.
1. Output channel 1 - fault red LED
2. Output channel 2 - fault red LED
3. Output channel 1 - green LED
4. Output channel 2 - green LED
5. IPS2050HQ-32
6. Output and power supply connector
For EMC:
• The SM15T39CA
GND tracks to protect the
coupling;
• in common mode surge testing, two single-layer capacitors (C1 and C2 - not included) must be soldered at
the predisposed locations;
• the IPS2050HQ-32
IEC61000-4-2, IEC61000-4-3, IEC61000-4-5 standards.
