Power supply
8.1
Direct voltage supply provided by customer
8.1.1
Requirements
The following requirements have to be fulfilled by a direct voltage supply provided by the
customer:
Supply voltage
In normal operation a non-grounded SELV voltage according to EN 60950-1: 2014, EN
60335-1: 2012, NFPA environment UL61010-2-201: 1st Edition 2014 with a typical voltage of
24 V is to be used.
The full performance, i.e. a maximum end speed of 800 mm/s, is achieved with the MED280
motor at a supply voltage of ≥28.8 V. In the process the maximum supply voltage of 38 V is
to be observed.
At 80% of the typical supply voltage (≥ 24 V * 0.8=19.2V) a maximum end speed of approx.
570 mm/s is achieved with the MED280 motor. Meaning that only limited performance is still
available.
In case of a fault scenario of the power supply unit the output voltage of the power supply
unit has to remain smaller than 60 V.
In case of a fault in the SIDOOR controller voltages of up to 60 V can occur.
