1 Power Protection and Conditioning 1 Surge Protective Devices (SPD) The STV25K DIN Rail Series This series provides point-of-use protection, at the dedicated equip ment level, against dam ag ing transients. Ideal for in stal la tion in elec tron ic control cabinets found in harsh industrial environments such as the factory fl oor or at remote locations. These devices provide 50,000 amps of surge pro tec tion, sinewave tracking, LED status in di ca tion and form C dry contacts. This DIN Rail series also pro vides pro tec tion on all electrical paths and comes with a standard ten year product war ran ty. The STV25K DIN Rail series surge suppressors are UL rec og nized to Standard 1449, 2 nd Edition. STV100K STV25K Surge pro tec tion devices are an ef fec tive and economical way to protect critical, mi cro pro ces sor based equipment/ ap pli ca tions from the damaging effects of transients. Transient voltage spikes are generated ex ter nal ly due to lightning, utility grid switch ing and electrical accidents or internally due to copiers, generators and large motors. Sola surge sup pres sion products quickly divert the high energy tran sients to levels that are safe for AC equipment. Sola/Hevi-Duty s industrial surge suppression devices protect equipment with low clamping levels on all electrical paths. This not only prevents catastrophic failure but also extends the life of any electronic equipment. These devices meet UL 1449, 2 nd Edition stan dards and provide AIC ratings for safe distribution panel use. These surge protection devices come in a compact design allowing the user to install the product as close as possible to the sensitive load. Surge suppression is one part of a total power quality solution. They can be used alone or in conjunction with other Sola/Hevi-Duty products to solve more complex power quality problems. Related Products DIN Rail Power Supplies Industrial Control Transformers Line Reactors The STV100K Hardwired Series Sola/Hevi-Duty s STV100K series is a hardwired surge suppressor designed for installation at the service entrance, branch panel or a dedicated sensitive elec tron ic load. These units feature all mode protection, LED and audible alarm status indication, sinewave tracking and form C dry con tacts. The STV100K series also contains the highest levels of safety built into the product including thermal fusing and a fault current fusing level of 65 kaic.
