522 Transformer 230Vac input, 13 Vac 1.6A output. In a standard 5 modules A type DIN box (87.5 mm).
850 Transformer 230Vac input, 13Vac 13VA and 24Vac 24VA outputs.
It can supply up to two videophones in parallel.
In a standard 5 modules A type DIN box (87.50 mm).
850K Transformer 230-127Vac inputs, 24Vac 24VA output. Used for videokits.
In a standard 5 modules A type DIN box (87.50 mm).
850KMV Transformer As above plus 12Vdc 0,2A output for memory board powering.
Is used on kits that include videointercoms with memory board.
893N1 Power Supply 230 Vac input, two 20Vdc 0,8A output (“+” and “+D” terminals). Both outputs are enabled
by signals on command terminals “+C” or “-C”. The Art.893N1 is used as video system power supply on
VIDEX digital systems (on which, in case of more entrances installation, is normally used the “+D” insulated
output) while on VIDEX traditional video entry system it is normally used as additional power supply.
In a standard 9 modules A type DIN box (157.5 mm).
