Telecommunications equipment play one of the most important roles in our society. When telecommunication and broadcast facilities go off-line not only are day-to-day communications halted for its users but critical services such as ambulance, fire, and police resources and responses are also compromised.

Critical telecommunication positions need surge protection not only for AC power supply, but also for communication lines and DC panels. Telecommunications equipment are vulnerable to lightning induced surges, and transients caused by switching components producing electrical noise in power supply.

Building on extensive experience AC DC Company developed advanced multi-stage surge protector that provides effective and reliable protection against surges and transients coupled with high grade EMI/RFI filtering. The protectors consists of 8 (eight)protection stages along with ground filtering as basic option.

AC DC MOS Protectors are surge protector of class I+II+III in one according to IEC 61643-1. The AC DC MOS Protectors reduced surge events in excess of 99.9% at a single point. Beside exceeding lightning protection standard IEC62305-4 AC DC MOS Protectors are are fullfill standard for electromagnetic (radio) interference suppression IEC60939-2.

Focuses on tracking the waveform and filtering the pollution generated in power network supply is the most important part in the protection of sophisticated telecommunication equipment . This pollution equals losses, unreliable performance, decrease asset life-spans, increase maintenance and downtime.

The problems of grounding pollution generated by electrical equipment inside the facility (3.5kHz-1MHz) is also the serious problem in the “New Electronic World” expecially for successful functioning of telecom equipment.

That new power network “ disease” have negative impact on functioning and reliability of telecommunication equipment.

The option for ground filtering annuls all disadvantages of high frequency resonance in grounding system.

The ground filtering prevents the ground loops, reduces feedback to sensitive electronic form ground and reduced the chance of equipment damage caused by near-strike lightning.

AC DC MOS Protectors are high performance surge protection products that provide comprehensive solutions for telecommunication systems.
