2.1 Power supply
The power supply of the M-SHEV product family comprises
three components:
• Switching power supply
• Charging device
• Lead battery
The choice of the switching power supply and the corre-
sponding charging device with battery varies according to the
specific power variant. For power supply with more than 72 A,
several power supply units (switching power supply / charging
device / battery) are used cascaded.The following figures may
vary depending on the size of the housing and number of
modules.
According to EN 12101-10, both the primary (switching power
supply unit) and the secondary (batteries) power supplies are
designed for delivering the full output independently from
each other.
