Operating Power Statistics
*
For both models, the in-rush current decays to the normal operating current in less than
200 msecs. For the AC model, the in-rush current of 100 A lasts for 2 msecs during a cold start
or during a warm start performed 60 seconds (or longer) after the AC was removed.
** This BTU assumes a system fully loaded with hardware option modules.
Caution –
The power supply on the Model 105 continues to regulate all outputs for
at least 20 msecs after AC power is removed. On the Model 100, the power supply
continues to regulate all outputs for at least 5 msecs after DC power is removed.
Note –
Logic ground and chassis ground are connected together internally within
the system.
Note – Power from the standby output is available whenever input power is
connected.
