Notes:
ƒ The current requirement refers to the nominal voltage of 24 V. With a lower voltage,
the current requirement increases linearly.
ƒ The values are maximum values. If the real currents are known, this can be
considered accordingly in the table.
ƒ The typical current consumption is approx. 10 ... 20 % lower.
ƒ When selecting the power supply unit, observe that there will flow a substantially
higher current for a short time when switching on the power supply unit. Select
power supply units that can supply this overcurrent and do not switch off.
ƒ The indicated current is a continuous current. If consumers are connected, more
current is required in the starting phase (e.g. device fans). Power supply units
therefore must have dynamic reserves.

Note!
When several devices are switched on, a very high initial charging current is
required. Power supply units without current limitation can be overloaded
(fault).
Lenze power supply units are equipped with an internal starting current
limitation. When several devices are switched on, there will not occur any
fault.
