Each unit consists of 9 (nine) & 100A protection stages along with ground filtering as basic option.

These protectors have special design to protect and improve functioning of low power devices like computers and other office equipment, up to large systems found in Broadband Wireless, Telecom, Automation Control, Medical, Instrumentation, Solar Photovoltaic, Military and similar application. more...

These protectors have option for ground filtering that annuls all disadvantages of high frequency resonance in grounding system preventing the ground loops, reduces feedback to sensitive electronic form ground and reduced the chance of equipment damage caused by near-strike lightning.

They are designed for protection of electronic appliances in L.V. supply systems against impulse surge and against high-frequency (electromagnetic) disturbance.They full fill and exceed standard requirement IEC61643-1 class I+II+III; IEC60939-2; UL1283

REDUCE THE TOTAL COST

AC DC MOS Protector present Multistage Protection system with 9 (nine) protection stage in one device, expelling needs of surge protectors in other protection boundary zones (LPZ0a/LPZ0b-LPZ3) and reducing surge current of 99.9% at a single point. (AC DC MOS Protector is surge protector of class I+II+III in one device according IEC61643-1;  and  B+C+D according VDE 0675). more...

The installation of AC DC MOS Protector expel needs of installation of surge protectors downstream to sub distribution board (acc. IEC62305-4) and significally reduced the total investment.

The complex analyses and multitude of criteria defined in lightning protection standards (IEC 62305 & ANSI/IEEE C62.41. 1-2) become the past. With AC DC MOS Protectors planning and installation of surge protection is not just reserved for an expert surge engineers but it is available to wide branch of professions. (electrician, construction builders, IT..)

AC DC MOS Protector Type - PI 780 Red Series

is specifically designed to protect, upgrade and improve functioning of computers, telecommunication, medical, audio, video and all sensitive electronic equipment.  High current capability, up to 100A per phase, makes these surge protec-tors ideal equally for sensitive equipment and industrial usage.

Technical Specifications:

The basic module of type AC DC MOS Protector - Red Series is 9 (nine) stages Single Phase Protector with modular configuration for single or three phase applications for load currents of up to 100A per phase.

Installation:

The AC DC MOS Protector - Red Series could be install in series or parallel configuration depending of total load (>100A<), with or without grounding filtering option. The place of installation of AC DC MOS Protectors Red series is Main Circuit Board (MCB) or Sub Distribution Board (SDB).

Reliability:

If the stages 2,4 and 6 are out of function, the stages 1,3,7 and 8 are still provide a high grade cascade bi-directional filtering along with ultimate (5-th) protections stage.

Philosophy:

The AC DC MOS Protectors have coordinated approach to lightning protection, surge and transient protection as well as grounding, an approach that embraces all aspects of potential damage. No single technology can effective protect electronic devices from the damaging effects of lightning and induced transients, which can severely damage or destroy electronic systems. In order to provide the optimum level of protection, AC DC has developed integrate 9 (nine) stages Surge protector that provides effective and reliable protection against surges and transients.

Approach:

AC DC MOS Protectors provides a systematic approach on two fronts: Surge protection and Bi-directional filtration. While there are companies and products that attempt one of these, AC DC MOS Protectors is the only product that seamlessly merges the two technologies. The unique multistage design provides the most advanced power filter protector.

Technology:

AC DC MOS Protectors Type-PI Red Series are surge protector of class I+II+III in one according to IEC 61643. The AC DC MOS Protectors reduced surge events in excess of 99.9% at a single point. They also full fill standard for electromagnetic (radio) interference  suppression IEC60939-2.

Design:

The integrated modular design allow easy placement where surge protection and filtration for sensitive equipment are needed.

Investment:

Installation of AC DC MOS Protector type - PI is excellent choice for investment in the quality of your power network supply, extended equipment life and reduce their down time and errors.

Application

These Surge protectors have been developed specially to cater critical locations of today's electrical equipment from nonstandard over-voltage conditions that may occur on sites with poor voltage regulation and poor grounding. These protectors have option for ground filtering that   annuls all disadvantages of high frequency resonance in grounding system.

The problems of grounding pollution generated by electrical equipment inside the facility (3.5kHz-1MHz) become the serious problem in the “New Electronic World”.  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.
