Unscreened Power Supply Line CDN
- ▸ Single-line 25 A power CDN, 150 kHz–230 MHz — the simplest M-series unit, designed for injecting common-mode RF disturbance into a single power conductor (typically PE / protective earth) per IEC 61000-4-6.
- ▸ 4 mm shrouded banana sockets, 250 VAC / 350 VDC rating — safe finger-proof connections for routine bench-top conducted immunity testing.
- ▸ 150 Ω common-mode impedance, 9.5 dB VDF, 50 Ω BNC RF port — standard IEC 61000-4-6 coupling profile for accurate test-level setting at 1, 3, and 10 Vrms.
- ▸ Protective earth (PE) line characterization — isolating the ground-conductor contribution to a product's conducted-immunity profile when the PE line is suspected of being a coupling path.
- ▸ DC-only powered devices and low-voltage DC supplies — sensors, transducers, and small instruments where the PE or single-conductor return is the test target.
- ▸ Educational and pre-compliance laboratories — the entry-level M-series model for in-house IEC 61000-4-6 capability and EMC training programs.
- ▸ Building-block use for multi-line setups — combine multiple CDN-M125E units when product-family standards require independent per-line injection rather than a single multi-conductor unit.
- ▸ NIST-traceable individual calibration with three-year warranty — ISO/IEC 17025 accredited calibration optional; ADA-515-X 150 Ω / 50 Ω calibration adapters available separately for IEC 61000-4-6 test-level setting; integrates into Com-Power Conducted Immunity Test Systems.
CDN-M125E Features
- ▸ Power-line CDN for PE (Protective Earth / Ground) line — 1 line configuration designed per IEC 61000-4-6 for conducted RF immunity testing of equipment power supplies
- ▸ 25 A per line continuous current rating covering 250 VAC / 350 VDC mains operation; 4 mm shrouded banana sockets for safe, repeatable EUT and AE power connections
- ▸ Frequency range 150 kHz to 230 MHz — covers the entire IEC 61000-4-6 standard band including the optional extended-band test region up to 230 MHz
- ▸ 150 Ω common-mode impedance profile per IEC 61000-4-6 with 9.5 dB voltage division factor (VDF) for accurate, repeatable test-level setting
- ▸ 50 Ω BNC (female) RF injection port — direct connection to immunity-test power amplifier output through standard 50 Ω coaxial cable
- ▸ 40 Vrms maximum RF input — supports test levels of 1, 3, and 10 Vrms per IEC 61000-4-6 with comfortable headroom
- ▸ High decoupling between EUT and AE ports — prevents auxiliary equipment from being stressed and prevents test signals from feeding back into the building mains
- ▸ Sturdy aluminum enclosure with carry handle — benchtop and floor-standing operation; ground stud on rear panel for proper reference-plane bonding
- ▸ NIST-traceable individual calibration with ISO/IEC 17025 accredited calibration available on request; all units shipped with calibration certificate
- ▸ Compatible with ADA-515-X 150 Ω / 50 Ω calibration adapters for test-level setting per IEC 61000-4-6 setup procedure
- ▸ Three-year warranty — covers manufacturing and workmanship defects
