Features and lnovations
The
US
150
power supply operates from mains
input woltages of
220-240
V
a.c.
(117
V
a.c. for
the
US
market) and has
5
supply outputs, of
which
4
feed the logic boards
( + 5, -5, + 12, -12
V
d.c.) and one feeds the coin mechanism lamps
( +5
V
d.c.).
There is a common eathing strip with tapped
holes for linking the mains earth to all metal parts
of the machine {door, control, panel, monitor
etc.), so eliminating interference from badly routed
cables, and guaranteeing easier compliance
with international standards for safety and
radiation.
The unit is supplied with a metal mounting plate
for easy fixing within the machine cabinet; the
plate may be mounted anywhere within the
cabinet, and the power supply unit can easily be
inserted into the plate and removed from it
without the use of any tools, see illustration on
page
6.
To cater for applications in cabinets or climates
with high ambient temperatures, there is the
possibility to add a small ventilator; this is
described on page
7.
(To order part n.
62010081).
In any event, a protective sensor switches of the
unit in case of overheating, and automatically
allows it to operate again only after regaining
the correct working temperature. In this way
component damage is avoided, and at the same
time the operator's attention is drawn to the
abnormal condition.
The unit is supplied with:
3-
pin connector for mains input
1 2-
pin connector for the coin mechanism lamps
1
9-
pin connector for the logic board supplies
16
M4
screws and shake-proof washers for the
earthing strip.
