The MTL MA30 series surge protectors 'cleans up' the effects of industrial noise and surges caused by lightning, switching devices, thyristor controls, transmission system overloads and power-factor correction circuits thus protecting electronic equipment power supplies and computer networks against the effects of 'noise pollution' induced in mains power supplies.
Industrial control systems and dc power supplies 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 MA30 units is critical. Ideally suited for protecting panel mounted equipment and typically used in the controls section of a motor control center (MCC), the MA30 range provides surge and RFI protected power.
With a unique ‘three-stage' combination of protection elements, The MA30 suppresses 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, MA30 units reduce both electromagnetic emissions and the susceptibility of the associated equipment to emissions from other sources. MA30 devices also offer ultimate installation flexibility. To protect circuits rated 30A or less, MA30 devices should be installed in series. To protect higher current circuits, simply install the MA30 in parallel.
An LED status indication facility is standard with the MTL MA30 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. MA30 units also offer short circuit protection. An optional remote monitoring unit is also available with audio and visual indication status, along with features such as a test switch for checking the monitoring circuitry and an audio alarm silence switch.
