The MTL MA15 series of surge protectors safeguards 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 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 center, the MA15 range provides surge and RFI protected power.
With a unique ‘three-stage' combination of protection elements, MA15 units suppress conducted RFI and voltage surges. The circuit elements are first, surge clipping components to absorb transient surges that may otherwise damage equipment, second a filter to suppress noise in the system and third, ‘ring' suppression. The third of these prevents surges causing the filter to ‘ring' (oscillate) under low load conditions, an effect that actually accentuates interference in most commercially available filters.
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 flexibility. 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 (certified 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.
