Technical Specications
ART.893N POWER SUPPLY (for video cabinets only: 2291V, 2291V4, 2291V8 and 2291V12)
The Art.893N power supply will supply an output voltage of 20Vdc (800mA continuous or a 1A surge). It is
used to power videophones and camera modules or can be used as a ‘booster’ supply when more than 2
videophones are required in an apartment. This power supply only has an output voltage when either a
-negative trigger is applied to the -C terminal or when a +positive trigger is applied to the +C terminal. At all
other times the + and +D outputs are o. The +D is a 20Vdc output that is protected with an internal diode.
A fused spur should always be used with this type of power supply. It is contained in a standard 9 module A
type DIN box for mounting on a standard DIN rail.
IMPORTANT NOTE: The 230Vac mains input terminals on this PSU should be connected to the mains supply
via a fused spur or preferably an all pole circuit breaker (refer to pages 29 - 30).
