5 Solid-Stte Switching Devices Generl dt Overview SIRIUS 3RF2 solid-stte switching devices The 3RF solid-stte switching devices relibly switch wide rnge of different lods with lternting voltges in 50 nd 60 Hz systems. Solid-stte switching devices for resistive lods Solid-stte relys Solid-stte contctors Function modules Solid-stte switching devices for switching motors Solid-stte contctors Solid-stte reversing contctors SIRIUS 3RF2 for lmost unending ctivity Conventionl electromechnicl controlger is often overtxed by the rise in the number of switching opertions. A high switching frequency results in frequent filure nd short replcement cycles. However, this does not hve to be the cse, becuse with the ltest genertion of our SIRIUS 3RF2 solid-stte switching devices we provide you with solid-stte relys nd contctors with prticulrly long endurnce for lmost unending ctivity even under the toughest conditions nd under high mechnicl lod, but lso in noise-sensitive res. Proved time nd gin in service SIRIUS 3RF2 solid-stte switching devices hve firmly estblished in industril pplictions. They re used bove ll in pplictions where lods re switched frequently minly with resistive lod controllers, with the control of electricl het or the control of vlves nd motors in conveyor systems. In ddition to its use in res with high switching frequencies, their silent switching mens tht SIRIUS is lso idelly suited for use in noisesensitive res, such s offices or hospitls. The most relible solution for ny ppliction Compred to mechnicl controlger, our SIRIUS 3RF2 solidstte switching devices stnd out due to their considerbly longer service life. Thnks to the high product qulity, their switching is extremely precise, relible nd, bove ll, insusceptible to fults. With its vrible connection methods nd wide spred of control voltges, the SIRIUS 3RF2 fmily is universlly pplicble. Depending on the individul requirements of the ppliction, our modulr controlger cn lso be quite esily expnded by the ddition of stndrdized function modules. Also for switching motors In order to chieve higher productivity, the switching frequency is continuously incresed. It is no problem for our SIRIUS solidstte contctors to switch motors. With induction motors up to 7.5 kw, they cn relibly withstnd even the highest switching frequencies. Even continuous chnge in the direction of rottion is possible with the solid-stte reversing contctors. Both versions cn be perfectly combined with components from the SIRIUS modulr system. Connecting with SIRIUS motor strter protectors or SIRIUS overlod rely cn be implemented without ny further steps. Alwys on the sunny side with SIRIUS Becuse SIRIUS 3RF2 offers even more: The spce-sving nd compct side-by-side mounting ensures relible opertion up to n mbient temperture of +60 C.

7 Solid-Stte Switching Devices for Resistive Lods In order to gurntee n optimized control method for different lods, the functionlity of our solid-stte switching devices cn be dpted ccordingly. The "zero-point switching" method hs proved to be idel for resistive lods, i. e. where the power semiconductor is ctivted t zero voltge. For inductive lods, on the other hnd, for exmple in the cse of vlves, it is better to go with "instntneous switching". By distributing the ON point over the entire sine curve of the mins voltge, disturbnces re reduced to minimum. Performnce chrcteristics The performnce of the solid-stte switching devices is substntilly determined by the type of power semiconductors used nd the internl design. In the cse of the SIRIUS solid-stte contctors nd solid-stte relys, only thyristors re used in plce of less powerful Trics. Two of the most importnt fetures of thyristors re the blocking voltge nd the mximum lod integrl: Blocking voltge Thyristors with high blocking voltge cn lso be operted without difficulty in networks with high interference voltges. Seprte protective mesures, such s protective circuit with vristor, re not necessry in most cses. For exmple, thyristors with 800 V blocking voltge re fitted in the devices for opertion in networks up to 230 V. Thyristors with up to 1600 V re used for power systems with higher voltges. Generl dt Mximum lod integrl Design One of the purposes of specifying the mximum lod integrl There is no typicl design of lod feeder with solid-stte relys (I²t) is to determine the rting of the short-circuit protection. Only or solid-stte contctors; insted, the gret vriety of connection lrge power semiconductor with correspondingly high I²t vlue cn be given pproprite protection ginst destruction from methods nd control voltges offers universl ppliction opportunities.

However, the devices re lso chrcterized by the specil versions with which it is even possible to chieve shortcircuit strength in fuseless design. rents.

Detiled informtion, for exmple in reltion to solid-stte Ring terminl lug connection bout the choice of het sink, is given in the technicl specifictions nd the product dt sheets.

Finger-sfety is provided in this cse too with cuits in the lod feeder. Consequently, specil precutions hve specil cover. to be tken ginst destruction, depending on the type of design. Function Siemens generlly recommends using SITOR semiconductor protection fuses. These fuses lso provide protection ginst Switching functions destruction in the event of short-circuit even when the solidstte contctors nd solid-stte relys re fully utilized. Alterntively, if there is lower loding, protection cn lso be provided by stndrd fuses or miniture circuit brekers. This protection is chieved by overdimensioning the solid-stte switching devices ccordingly. The technicl specifictions nd the product dt sheets contin detils both bout the solid-stte fuse protection itself nd bout use of the devices with conventionl protection equipment. The solid-stte switching devices for resistive lods re suitble for interference-free opertion in industril networks without further mesures. If they re used in public networks, it my be necessry for conducted interference to be reduced by mens of filters. This does not include the specil solid-stte contctors of type 3RF23..-.CA.. "Low Noise". These comply with the clss B limit vlues up to rted current of 16 A. If other versions re used, nd t currents of over 16 A, stndrd filters cn be used in order to comply with the limit vlues. The decisive fctors when it comes to selecting the filters re essentilly the current loding nd the other prmeters (opertionl voltge, design type, etc.) in the lod feeder. Suitble filters cn be ordered from EPCOS AG. You cn find more informtion on the Internet t: Siemens

In the event of fult, n output is ctuted nd one or more LEDs indicte the fult. Design Mounting Esy snpping onto the 3RF21 solid-stte relys or 3RF23 solidstte contctors estblishes the connections to the solid-stte switching devices. Becuse of the specil design, the strightthrough trnsformer of the lod monitoring module covers the lower min circuit connection. The cble to the lod is simply pushed through nd secured with the terminl screw. Function The function module is ctivted when n "ON" signl is pplied (IN terminl). The module constntly monitors the current level nd compres this with the setpoint vlue.

Design Mounting Esy snpping onto the 3RF21 solid-stte relys or 3RF23 solidstte contctors estblishes the connections to the solid-stte switching devices. Becuse of the specil design, the strightthrough trnsformer of the function module covers the lower min circuit connection. The cble to the lod is simply pushed through nd secured with the terminl screw. Function Power control The power controller sets the lod current of the solid-stte switching device depending on setpoint vlue s percentge. It does not compenste for chnges in the mins voltge or lod resistnce. The modultion, the On/Off rtio or the phse ngle, remins unchnged ccording to the setpoint vlue. The utonomous power control is performed between 0 nd 100 % of the setpoint selection. Full-wve control If the left potentiometer t R is set to 0 s (= fr left), then the power controller opertes ccording to the principle of full-wve control.
