BTicino E56 - Power Supply for MyHome SCS BUS - 110-240 Vac - 6 DIN Modules

BTicino E56 - Power Supply for MyHome SCS BUS - 110-240 Vac - 6 DIN Modules

The BTicino E56 power supply is designed for MyHome automation systems with SCS BUS. It provides safety extra-low voltage (SELV) power and is suitable both as a main power supply and as a supplementary power supply for local automation devices.

Main Features:
Universal input power supply 110-240 Vac at 50/60 Hz.
Two safety extra-low voltage outputs that can be used alternatively and not simultaneously:
- SCS output: 27 Vdc - 1.2 A for MyHome BUS
- Output 1-2: 28.5 Vdc - 1.2 A for local supplementary power supply
Electronic protection against overload and short circuit.
Class II double insulation device (SELV).
DIN rail installation, 6 modules.

Operation:
The power supply can be used in two modes:
- SCS BUS power supply via dedicated SCS terminals
- Local additional power supply via terminals 1-2
The two outputs cannot be used simultaneously. When using output 1-2 as an additional power supply, no other outputs should be connected.
