6.4.2 Calculation example
Calculation example 6- Verdrahtung_PNOZ_ml2p_Leitungslänge-Spannungsabfall-Beispiel ` The PSS SB BUSCABLE LC is used in accordance with the pin as-
signment in section 6.2.2.
Voltage drop per 10 m and per 100 mA: 0.1 V
Key:
` I0: Module's consumption.
` I1 ... I5: Load current taken from the module
` U1 … U4: Voltage drop on the respective connection path
