Power Supply Requirements - Siemens SIDOOR ATD401W System Manual

Power supply requirements

NOTICE
The DC power supply for the SIDOOR ATD4xxW controller may be used only with firmware
version ATD4xxW > = 1.04.
The following requirements must be met by the building DC power supply:
Supply voltage
In normal operation a non-grounded SELV voltage according to EN 60950-1: 2014, NFPA
environment UL61010-2-201: 1st Edition 2014 with a typical voltage of 36 V is to be used.
Note 1: Operation of the SIDOOR device is possible down to 19.2V. However, this is
associated with performance loss for the drive with respect to the achievable forces, speeds
and acceleration.
Note 2: With >45V, irreversible damage is done to the SIDOOR device!
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.
Supply current
Normal operation requires an operational peak current of up to 14A for up to 3s as well as a
continuous current of up to 9A. Smaller current values can result in operating faults,
depending on the selected settings (ramps, end speeds, forces) and the door properties
(friction, weight).
To ensure triggering of the automatic circuit breaker in case of a fault of the SIDOOR
controller, the utilized power supply unit must have the following properties (see figure
below):
● ≥13A continuous current, even in case of a short-circuit
- OR -
● Effective short-circuit current ≤8ARMS, period duration ≤10s, peak current ≤55A
In the case of a fault on the part of the power supply unit or of the SIDOOR controller the
current is limited by the miniature circuit breaker C8 Automat according to EN 60898-1.
