The MA30 Series of surge protection devices protects electronic equipment power supplies and computer networks against the effects of "noise pollution" induced in mains power supplies. MA30 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 and dc power supplies utilising 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 centre (MCC), the MA30 range provides surge and RFI protected power. Suitable for AC or DC application, MA30 units reduce both electromagnetic emissions and the susceptibility of the associated equipment to emissions from other sources.
