Supply Units With Integrated Mains Contactor
9.4.5 Signal Sequences When Switching HMV Supply Units ON and OFF
Switching On
Risk of damage to the supply units when they
are switched on simultaneously!
With 3 or more HMV supply units at common supply mains: Switch on supply
units one after the other with a time interval of at least 0.5 seconds so that
the inrush currents are not added.
In the switch-on sequence of the supply unit, the supplying mains is loaded
with the current I
L_trans_max_on
for the purpose of analysis. During the unloading
process, voltage overshoot can occur at the mains components connected in
the incoming circuit (e.g. mains filters) due to inductances connected in the
incoming circuit, e.g. the leakage inductance of the mains transformer.
