Welcome to Shanghai International Charging Pile Exhibition 2018! TDK is presenting EPCOS products that are used in charging piles for a wide range of application such as the DC link, circuit protection, input and output filtering, and power disconnection. The focus is on aluminum electrolytic and film capacitors, power EMC filters, surge arresters and high-voltage contactors, as well as PTC thermistors and varistors. We’re looking forward to your visit!
High-voltage contactors - Portfolio extended for high current capabilities up to 500 A
The HVC series of high-voltage contactors now features the new HVC300 and HVC500 types with current capabilities of 300 A and 500 A, respectively. The new contactors can switch high voltages of up to 900 V DC, while types for 1200 V DC are available on request.
Varistors with increased permissible operating temperature
The leaded EPCOS metal oxide disk varistors are now approved for an increased operating temperature of 105 °C (previously 85 °C). The reason for this is the recertification of the B722* series of varistors in accordance with UL 1449, 4th Edition, and IEC 61051. Raising the permissible operating temperature to 105 °C also changes the climate category from 40/85/56 to 40/105/56. The flammability of the epoxy enclosure complies with UL 94 V-0. The monolithic EPCOS varistors are available with rated voltages of between 11 VRMS and 1100 VRMS and, depending on type, can withstand surge currents of up to 20 kA (8/20 µs).
Film capacitors with high pulse strength and current capability
TDK’s EPCOS MMKP capacitors employ a film that is metallized, offering particularly high pulse strength as well as a high current capability. Depending on the type and frequency, the permissible current can be up to more than 10 ARMS. A further outstanding feature is the compact design of the MMKP series. The capacitors have dimensions of between 4 mm x 9 mm x 13 mm and 11 mm x 18.5 mm x 18 mm and are available with lead spacings of 10 mm and 15 mm.
The B32641B* and B 32642B* series of rugged MMKP capacitors are designed for voltages of 630 V DC or 1000 V DC and cover a capacitance range from 4.7 nF to 150 nF. The maximum operating temperature is +110 °C. The main applications are circuits that operate with high frequencies and currents, including resonant circuits of power supplies with an LLC topology.
EMC filters with high performance in a very compact design
TDK’s B84243A8* series of EPCOS EMC filters currently comprises seven different types that are designed for currents of between 3 A and 60 A – based on a rated temperature of 50 °C. Furthermore, the filters are characterized by their very compact dimensions: Depending on the exact model, these typically lie between 190 mm x 40 mm x 95 mm and 250 mm x 85 mm x 120 mm. Recessed connections permit optimum access to the mounting bracket, making the filters suitable for installation in switching cabinets or where limited space is available. The adherence to the EMC limits defined in EN 61800-3 C1 for motor cable lengths of up to 25 m and C2 of up to 50 m has been verified by measurements of various commercially available frequency converters with input rectifier stages.
