MULTI-STAGE SURGE PROTECTION

 www.acdc-dcac.eu

Every ACDC Surge Protector Type -PI (740; 780; 7125; 7200) Red Series have free contact alarm as basic option.  The alarm is activate in two cases:   

1. When some of the protection stages (2, 4 or 6) are damaged or burned and Red Led is ON.  Alarm contacts 1-3 are 

                               

permanently closed.  

2.  When the ground of the power grid system is not well performed (pour grounding). Alarm contacts1-3 are closing with frequency of 2Hz (0,5s)
Red led is blinking.                                 

Free contacts are on the cover of the protector with contact no. 1 and 3. (see picture)                                     
The contact is a optocoupler with maximum value of voltage 70VDC and current of 10mA. In normal condition it is open.
