RSHN-2010D | TDK Lambda | Single phase EMI power filter

RSHN is a single-stage high attenuation filter with ferrite core; The biggest difference from the previous RSKN (nanocrystalline two-stage chassis installation) is that DIN rail and SCCR have higher short-circuit tolerance and lower cost, and the high-frequency attenuation is slightly weaker than RSKN

Core parameters

Rated: 250V AC/DC, 10A

Attenuation: Common mode ≥ 25dB (0.1-30MHz); Differential mode ≥ 25dB (0.3-30MHz)

Maximum DC resistance: 60m Ω

Leakage current: 250V/60Hz, maximum 1mA

SCCR: 14kA (much higher than RSKN series 5kA, with strong short-circuit withstand capability)

Installation: DIN 35mm rail buckle installation with safety terminal protection cover

Working temperature: -25~+85 ℃; UL/CSA/ENEC, RoHS certification

Size: 98 × 52 × 43.4mm, weight approximately 260g, DK Produc

Product Positioning

Single phase 10A, control cabinet rail built-in EMI filter, suitable for directly clamping the rail inside standard electrical cabinets without additional holes for fixing; Used to suppress the conduction interference of switching power supplies and servo drives, and meet CE EMC testing requirements; AC/DC dual-use.

Selection comparison: RSKN is a chassis lock screw, two-stage nanocrystal, with stronger high-frequency noise suppression; RSHN is a rail mounted, ferrite single-stage, easy to install, with higher SCCR and better cost.

Typical application scenarios

1. Industrial automation control cabinet (main scenario)

PLC control cabinet, small servo/stepper driver (single-phase 220V, ≤ 2kW servo)

Automated production line control box, robot electrical control cabinet, terminal box

Advantages: Direct card DIN rail, standardized wiring inside the cabinet, convenient mass production of electrical cabinets

2. Industrial testing and instrumentation equipment

Desktop testing power supply, aging testing fixtures, laboratory testing instruments

Laser and ultrasonic small-scale processing equipment (medium level conducted noise)

3. Communication and security power system

Communication auxiliary AC-DC power supply, high-power security host, access control centralized power supply cabinet

4. Medical equipment (standard leakage current version)

Non patient contact medical equipment, testing and analysis instruments

The maximum leakage current of the standard version is 1mA; for floating and patient contact medical equipment, the RSHN-2010LD low leakage current version (0.1mA) should be selected

5. DC system within 250V

Can be used for EMI filtering in DC circuits, energy storage, and noise suppression in DC power supply cabinets

Key points for design and usage

1. DIN rail installation: The filter should be placed as close as possible to the AC input terminal of the electrical cabinet, and the input side cable should be shortened; The shell is reliably grounded through guide rails.

2. Input output separation: Do not bundle the input and output lines of the filter in parallel to prevent noise coupling.

3. Current derating: Rated at 10A, it is recommended to reserve a current margin of ≥ 20% in high-temperature environments.

4. SCCR=14kA: Excellent short-circuit withstand performance, and a front-end circuit breaker can meet UL short-circuit safety requirements.

5. Leakage current superposition: Multiple filters are connected in parallel in the electrical cabinet, and the total leakage current superposition may cause the leakage protector to malfunction.
