Schurter expands its wide range of current compensated chokes with high current types for PCB mounting. The new DKIH series are available for single and three phase applications with rated currents from 10 to 50 amperes. Due to its open design, the chokes are light weight and compact, ideally designed to suppress EMI noise caused by power applications on the PCB.

Like all other aspects of electronic design, the power portion is oftentimes built today using discrete components on printed circuit boards. With the trending integration of components, to achieve smaller and smaller form factors, thermal problems and high currents on the PCB can arise. It also becomes increasingly challenging to meet EMC requirements with a filter package due to the resulting space constraints; therefore a filter on PCB with discrete components is a good solution. Next, the capacitors and a common mode choke, with asymmetrical effective inductance, are very effective to dampen EMI noise.

The new DKIH-1 series is suitable for single phase AC or DC applications from 10 up to 50 amperes. Light weight and compact, the common mode chokes are easily placed on the PCB with through hole technology (THT). They are designed and approved according IEC 60938, UL 1283 and CSA 22.2 no. 8. The voltage rating is 300 VAC (IEC, UL) and 250 VAC (CSA).

The new DKIH-3 series is suitable for three phase AC applications from 10 up to 50 amperes. The common mode chokes are also designed according IEC 60938 and are rated 600 VAC, making them suitable for many applications.

The DKIH-1 and -3 have a wide temperature range of -40 to +100°C. They are available with a standard pin out or customer specific pin out. Variations in the winding are also available on request.

Technial Data DKIH-1:
- Rated voltage: 300 VAC (UL, ENEC), 250 VAC (CSA), 425 VDC
- Rated currents: 10 to 50 A (ENEC / UL / CSA) at 40°C
- Rated inductance: 0.15 to 0.80 mH
- Other pin outs available on request

Technical Data DKIH-3:
- Rated voltage: 600 VAC
- Rated currents: 10 to 50 A at 40°C
- Rated inductance: 0.08 to 1.10 mH
- Other pin outs available on request

Application:
- Frequency converters for photovoltaic or energy storage
- Charge stations for electric vehicles
- UPS-systems
- Switching power supplies

Power management company Eaton offers Dumeco DC switch-disconnectors to help solar PV equipment manufacturers and installers gain a competitive edge within the increasingly significant solar power market. These innovative products stand alone as cost-effective, reliable and safe solutions; they also integrate efficiently and easily with matched Eaton components into a continuous channel that transports energy safely from the solar module to the power grid.

The DC switch-connectors are being made available in four frame sizes; the largest has 800 A, 1000 A and 1250 A options, while the smallest offers 63 A, 80 A and 100 A versions. Accordingly, the devices are suitable for applications ranging from residential and light commercial rooftop sites to large commercial and utility scale installations, as well as solar combiner box and inverter equipment.

This switchgear is available in 2-pole configurations that reduce the need for bridging links between the poles; this cuts installation time and copper costs. Bi-directional pole connection gives installation flexibility. The units’ minimal footprint of up to 52 per cent smaller than any competing product allows installation space savings. An independent manual operating mechanism controls special self-cleaning roller contacts which provide long term safety and reliability.

Operation is through either a direct handle or an extension shaft of up to 600 mm and handle for thru-the-door interlocking. IP65-rated grey or red/yellow K Line handles are available, with both padlock and cylinder lock versions. Door interlocking configurations include a ‘defeatable’ option in the ON position for fault finding. An auxiliary switch set is also available; this offers 1NO+1NC contacts.

The Dumeco DC switch-connectors are rated to 1000 V DC, are compliant with standard EN-IEC 60947-3 and have CE, CCC, RoHS and EAC certifications. They offer high short circuit ratings and operate to utilization category DC-21B. The units are suitable for base plate mounting.

This new range of DC switch-connectors is built to handle the most demanding of PV applications, while providing reliable isolation to ensure safe operation within an installation. Perfectly aligned with the robust Dumeco AC switch-disconnectors, it enables an excellent all-round AC/DC package. The products offer an attractive solution to distributors, installers and manufacturers due to their competitive pricing, cost-saving features, proven reliability and compact, flexible design. They form part of Eaton’s comprehensive global portfolio that serves the renewable energy segment.
