Greater availability and extended flexibility

Siemens has adapt­ed the elec­tri­cal and mechan­i­cal design of the Sinam­ics S120 Chassis‑2 to meet today’s and tomor­rows mar­ket require­ments. The new fre­quen­cy con­vert­ers are designed to meet the very high­est demands with state-of-the-art com­po­nents, an inno­vat­ed cool­ing con­cept with speed con­trolled fan and is like always type and sys­tem test­ed to ensure the very high­est reli­a­bil­i­ty and availability.
The devices them­selves are both lighter and small­er, and com­pat­i­ble to all their pre­de­ces­sors. Large­ly due to the improved elec­tri­cal prop­er­ties and the new robust mechan­i­cal design, the new Sinam­ics S120 Chassis‑2 devices can be sim­ply inte­grat­ed into exist­ing plants. The Data­Ma­trix code pro­vid­ed on the type plate allows tech­ni­cal data and cer­tifi­cates to be accessed at any time – direct­ly open­ing up the pos­si­bil­i­ties of Indus­trie 4.0 for the user. The con­vert­ers are par­tic­u­lar­ly suit­ed for dynam­ic appli­ca­tions which ben­e­fit from the com­bined DC-Link to improve the ener­gy effi­cien­cy in the process like steel mills, paper mills, cranes, con­vey­ors, test rigs and many more.
A par­tic­u­lar­ly impres­sive fea­ture of the new pow­er mod­ules is their com­pact size. By mak­ing some opti­miz­ing touch­es to the design, Siemens has suc­ceed­ed in reduc­ing the foot­print of the new devices by between 30 and 60 per­cent – depend­ing on the mod­el – com­pared to the famil­iar Sinam­ics S120 devices, pro­vid­ing improved per­for­mance with a stan­dard­ized design over the com­plete range.
Sinam­ics S120 Chassis‑2 or Cab­i­net Modules‑2 are com­pat­i­ble with the famil­iar Sinam­ics and Mas­ter­drives series, guar­an­tee­ing sim­ple inte­gra­tion and retro­fitting into exist­ing plants. Their improved cool­ing con­cept makes for greater avail­abil­i­ty, while help­ing to min­i­mize the cost of cool­ing and pre­vent unwant­ed dam­age. The use of stan­dard­ized ter­mi­nals makes for sim­pli­fied instal­la­tion and more rapid diagnosis.
Whether users opt for Sinam­ics S120 Chassis‑2 or Cab­i­net Modules‑2, either design can be dimen­sioned for a pre­cise fit no mat­ter how chal­leng­ing the appli­ca­tion. The stan­dard pulse fre­quen­cy has been increased to 2.5 kilo­hertz to pro­vide sig­nif­i­cant­ly increased sys­tem effi­cien­cy and min­i­mized der­at­ing. Their high-per­for­mance IGBTs and reli­able capac­i­tors, robust elec­tron­ic mod­ules, inno­v­a­tive cool­ing con­cept and vari­able-speed fans as well as type and sys­tem test­ing make Sinam­ics S120 Chassis‑2 and Sinam­ics S120 Cab­i­net Modules‑2 excep­tion­al­ly durable while reduc­ing upkeep, down­time and main­te­nance costs.
