RSKN-2006 | TDK Lambda | Single phase two-stage EMI power filter)

RSKN-2006 is a power line EMC filter produced by TDK Lambda, belonging to the RSKN series. It has a rated current of 6A and a rated voltage of 250V AC/DC. It is mounted on a chassis mount and connected with screw terminals. ‌‌

Main Parameters

Product type: EMC filter (single-phase power line filter)

Rated voltage: 250 VAC/250 VDC

Rated current: 6 A

Leakage current: 1 mA

Working temperature: -25 ° C to+85 ° C

Dimensions: 107mm in length, 47mm in width, and 26mm in height

Certification standards: EN 60939, UL 1283, CSA C22.2 No.8

Application scenarios

Function: Connected to the front end of single-phase AC input, it suppresses the intrusion of power grid noise into the equipment, and also suppresses the conducted interference generated by the internal switching power supply and driver of the equipment, meeting EMC standards such as CE/UL.

1. Industrial equipment (most commonly used)

Small industrial control box, PLC control cabinet, industrial touch screen

Servo/stepper drive, small frequency converter (power ≤ 1.5kW, 6A current matching)

Industrial testing instruments, testing and measuring equipment, sensor power supply box

2. Medical equipment (requiring EMC safety regulations)

Medical monitoring equipment, small medical analyzers, laboratory instruments

Two level high attenuation, strong suppression of high-frequency switch noise, meeting the EMC requirements of medical equipment

3. Power supply and communication equipment

Switching power supply, AC-DC power module, front-end filtering of the whole machine

Communication base station auxiliary power supply, security monitoring high-power host

DC power supply system within 250V DC (supporting DC input filtering)

4. Automation and high-end consumer devices

Robot small control cabinet, 3D printing industrial machine

Laser equipment, ultrasonic equipment (such equipment has high internal high-frequency noise and is easily transmitted to the power grid)

Key points for design and usage

1. Installation location: As close as possible to the AC input port of the equipment, the filter housing should be reliably connected to the metal casing of the equipment (grounding is key for EMI)

2. Current margin: Rated at 6A, it is recommended to leave at least 20% margin for long-term operation to avoid high temperature derating

3. Leakage current: 250V/60Hz, maximum leakage current 1mA, not suitable for floating medical equipment that is extremely sensitive to leakage current

4. Topology: Two stage LC filtering, compared to single-stage filtering, has stronger suppression of broadband noise and is suitable for products that are easy to test for EMC

Selection comparison

Same series: RSKN-2010 (10A), RSKN-2020 (20A), RSKN-2030 (30A), with the same structure and appearance, only different current and internal resistance
