Power consumption calculation example
The power supply module (MSE 1201, MSE 1202) provides the electrical power for
further modules and encoders. If the power provided does not suffice to operate
the desired system configuration, a further power supply module must be used.
The power consumption is specified for each module (see table). The power
consumption of the connected HEIDENHAIN encoders can be calculated from
the catalog data (supply voltage x current consumption). For all other consumers
(e.g. inductive and analog sensors), the connected load must be known. The sum
power of all consumers must not exceed the rated power of the power supply
module(s).
The following example illustrates this calculation.

power supply module.
