Definitions
- Low-side switch
- A low-side switch completes the circuit on the ground side. It is intended to sink power rather than provide power.
- Ui – Maximum input voltage
- The maximum voltage (peak a.c. or d.c.) that can be applied to the connection facilities of apparatus without invalidating the type of protection.
- Ii – Maximum input current
- The maximum current (peak a.c. or d.c.) that can be applied to the connection facilities of apparatus without invalidating the type of protection.
- Pi – Maximum input power
- The maximum power that can be applied to the connection facilities of apparatus without invalidating the type of protection.
- Ci – Maximum internal capacitance
- The maximum equivalent internal capacitance of the apparatus which is considered as appearing across the connection facilities.
- Li – Maximum internal inductance
- The maximum equivalent internal inductance of the apparatus which is considered as appearing at the connection facilities.
- Uo – Maximum output voltage
- The maximum voltage (peak a.c. or d.c.) that can appear at the connection facilities of the apparatus at any applied voltage up to the maximum voltage.
- Io – Maximum output current
- The maximum current (peak a.c. or d.c.) in apparatus that can be taken from the connection facilities of the apparatus.
- Po – Maximum output power
- The maximum electrical power that can be taken from the apparatus.
- Co – Maximum external capacitance
- The maximum capacitance that can be connected to the connection facilities of the apparatus without invalidating the type of protection.
- Lo – Maximum external inductance
- The maximum value of inductance that can be connected to the connection facilities of the apparatus without invalidating the type of protection.
- Lo/Ro – Maximum external inductance to resistance ratio
- Maximum value of ratio of inductance to resistance that can be connected to the external connection facilities of the electrical apparatus without invalidating intrinsic safety.
