After the electric current supply of member is cut off, controller can not learn whether the load fault unit is pulled out by current detection circuit
Go out or replace, in the case of no manual intervention, controller can only be closed conducting power switch by being interrupted, detection load electricity
Stream, the case where to know load end.This brings new security risk to power-supply unit and load unit.
When not needing load unit work, to save power consumption, controller, which disconnects, gives load unit power switch, electricity
Stream is detected as zero, and controller can not perceive whether load unit is pulled out or replaces.
When load unit accesses power-supply unit for the first time, if the supply port of power-supply unit is in and has in grafting
Electricity condition may bring circuit devcie on load unit and exceed defined upper surge, load unit device may be caused because of electricity
Source impact is impaired.
The supply port of power-supply unit, which is in, electricity condition, causes at this time such as access wrong load or because of maloperation short
Road, electric leakage may lead to unnecessary harm.
