The MA15 Series of surge protection
devices protects electronic equipment and
computer networks against the effects of
‘noise pollution’ induced in power supplies.
MA15 units ‘clean up’ the effects of industrial
noise and surges caused by lightning, switching
devices, thyristor controls, transmission
system overloads and power-factor correction
circuits.
Industrial control systems utilizing programmable
logic controllers (plc) and industrial
computers are particularly vulnerable
due to the aggressive electrical environments
for which they are intended, such as process
plants, factories and water treatment sites.
Although industrial computers and plcs are
designed to be rugged, the extra protection
provided by the DIN rail mounting MA15 units
is critical. Ideally suited for protecting panel
mounted equipment and typically used in the
controls section of a motor control centre
(MCC), the MA15 range provides surge and
RFI protected power.
With a unique ‘three-stage’ combination
of protection elements, these units suppress
conducted RFI and voltage surges.
The circuit elements are fi rst, surge clipping
components to absorb transient surges that
may otherwise damage equipment, second
a fi lter to suppress noise in the system and
third, ‘ring’ suppression. The third of these
prevents surges causing the fi lter to ‘ring’
(oscillate) under low load conditions – an effect
that actually accentuates interference
in most commercially available fi lters.
Suitable for AC or DC application, MA15
units reduce both electromagnetic emissions
and the susceptibility of the associated
equipment to emissions from other
sources. MA15 devices also offer ultimate
installation fl exibility. To protect circuits rated
15A or less, MA15 devices should
be installed in series. To protect
higher current circuits, simply
install the MA15 in
parallel.
An LED status indication facility is standard
with the MA15 units. This displays both ‘power
on’ and that protection is present. Thermal fusing
is also incorporated into each 18kA rated
device as an additional safety feature. MA15
units also offer short circuit protection for
added peace of mind.
MA15 devices are UL 1449 Recognized
Components (certifi ed by UL for both US and
Canadian requirements) and exceed the requirements
of IEC 61000-4-5. As MA15 units
suppress conducted RFI and voltage surges
they enable associated equipment to
comply with this aspect of
European ‘CE’ mark
standards.
