ET-PS is a power supply module dedicated for ET-DCS controller.
Its design allows parallel operation, what means that any number of PS modules can be installed, evenly sharing load between themselves. ET-PS modules may be installed in any location on a bus, and may be added without restrictions at any moment e.g. when extension of a controller causes increased energy consumption or when we want to make redundancy of controller's supply system. Addition or exchanging ET-PS module does not require stoppage or restart of a controller.
ET-PS power supply has internal diagnostic system, which transfers actual working parameters and error information to the CPU ET-CP. Programmer can use this data e.g for alarming needs or presentation of controller's status to a user.
