Insulation Requirements
Insulation requirements for lab power supplies and other current/voltage sources for circuits connected to the HiL
system:
•
The power supply to live circuitry must be safely isolated from the supply voltage. For example, use a car
battery or a suitable lab power supply.
•
Only use lab power supplies with dual protection for the supply network (with double/reinforced insulation
(DI/RI)). This requirement is met by lab power supplies that comply with IEC/EN 60950 or IEC/EN 61010.
•
The lab power supply must be approved for use at a height of 2000 m and in ambient temperatures of up to
40 °C.
