*) Voltage derating as a function of installation altitude:
When supplying the electronics with voltages of 460 VAC phase to phase (maximum 300 VAC with respect
to ground) operation is permitted up to 4500 m. A maximum of 400 VAC phase to phase (maximum 230 V
AC with respect to ground) is permitted up to 5000 m. At higher altitudes or a higher voltage, there is no
longer "safe electrical separation" - but only basic insulation.
**) Definition, pollution degree 2:
Normally, only non-conductive pollution occurs. However, occasionally conductive pollution can be expected
for a short period of time if the electronic equipment is not operational.
Wait time, recovery time:
Each time that the line supply voltage is connected (e.g. via a line contactor):
The quenching capacitors in the unit are charged.
The wait time until the SIMOREG CCP is ready, is
approx. 3 s
After
one
quenching operation:
The time until the SIMOREG CCP is ready again depends on the operations during the quenching
process and immediately afterwards.
The quenching capacitors in the SIMOREG CCP are again recharged to the required value,
duration
approx. 10 s
.
The chopper resistors, which convert the energy into heat when the armature current is reduced,
require a cooling time.
This is calculated using a software algorithm, and depending on the energy that is dissipated
during the quenching operation, is up to
approx. 20 min
.
