ART.521 POWER SUPPLY
The Art.521 power supply will supply an output voltage of 13.5Vdc
(800mA continuous or a 1A surge)
and is
protected by a fall back circuit
(there are no internal fuses on the primary or secondary side of the transformer)
.
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).
