Description
The power supply must be used to supply power to the MY HOME and Lighting
Management systems. On the output, the unit supplies a 27 Vdc continuous low voltage,
with a maximum current of 1 A (BUS terminals). It is electronically protected (without
fuses) against short circuit and overload.
It’s a double insulation safety device in accordance with CEI EN60065, and can therefore
be used in conjunction with a SELV source in accordance with paragraph 11.1.2.5 of CEI
64-8-4.
The power supply unit is fitted inside a 8 DIN rail module enclosure, and its installation
must be in accordance with the regulations of the country of use.
In general, the following requirements must be met:
- The power supply must always be installed in appropriate enclosures.
- The device must be kept away from water drips and sprays.
- Care must be taken not to obstruct the air vents.
- A two-pole circuit breaker must be installed, with contact separation of at least 3 mm
located nearby the power supply. The circuit breaker is used to disconnect the power
supply from the mains, and to protect it.
