EM Test NX7 Overview
Multifunctional Test Generator for Transients
(EFT/Burst, Surge, Power Fail & Ringwave) up to 7 kV
The compact NX7 offers, a multifunctional test generator that meets and exceeds international and product-specific transient and power fail requirements. The compact NX7 series expands the voltage range of the compact NX5 series to 7.0 kV, and will replace the UCS 500N7 family in future. The generator has a modular design and can be manufactured with different combinations.
Application
COMPACT NX7 - COMPACT TESTER FOR EFT/BURST, SURGE AND POWERFAIL
Featuring an easy-to-use color touch screen, the NX7 provides an economical solution for pre-compliance immunity testing as well as full-compliance testing and CE Marking. Its internal single-phase Coupling/Decoupling Network (CDN) can be extended for testing three-phase EUTs by means of an automatically controlled external CDN up to 200 A per phase. AMETEK CTS supplies a large range of accessories for various applications such as magnetic field tests and more.
Benefits
ALL IN ONE - ALL YOU NEED FOR YOUR TESTS
The NX7 can be operated manually from the intuitive front touch screen or remotely via its built-in Ethernet, USB or optical interface. Failure inputs allow control of an ongoing test sequence based on the state of the EUT. Monitoring outputs (BNC) offer easy signal verification and measurements. For enhanced safety requirements, features like interlock and a warning lamp are available.
NX7 is the first generator that recognizes the connected EUT power configuration. Only coupling selections to active lines are enabled. Non existing lines will be disabled from the menu settings. Pre-programmed routines with common Test Standards allow maximum user convenience. Quick Start Test routines where parameters can be changed during susceptibility level evaluation are also available.
EASY TO OPERATE
Software
IEC.CONTROL SOFTWARE FOR CONTROL AND DOCUMENTATION
Outstanding user convenience, clearly structured windows and operation features, EM TEST's comprehensive standards library along with the flexibility to easily generate user specific test sequences are the main features of iec.control software. The software will be automatically configured in accordance with the connected EM TEST generators. Extensive reporting capabilities help the user to create test reports that meet international requirements. The iec.control is supported by Windows 7, Windows 8 and Windows 10. Remote control is achieved either via Ethernet or optical interface with USB connector at the PC side. The iec.control supports various interfaces for the communication to external measuring devices.
AUXILIARY DEVICES
COUPLING NX7 - 3PHASE COUPLING/DECOUPLING NETWORKS FOR BURST AND SURGE
AMETEK CTS offers a range of fully automatic 3-phase coupling/decoupling networks for burst, surge and ringwave to extend the test capability for three-phase EUTs. The networks have a rated current of up to 200 A.
VARIAC NX 1-260-16 - MOTORISED VARIAC FOR VOLTAGE VARIATION
A motorized variac is offered as an alternative to the tapped autotransformers for voltage dips/interruptions and voltage variation tests as per IEC/EN 61000-4-11. The motorized variac can also be used for automated magnetic field tests.
V 4780 - TAPPED VOLTAGE TRANSFORMER FOR VOLTAGE DIPS
The V 4780 tapped autotransformer is designed to supply the required voltages as per IEC/EN 61000-4-11 to perform voltage dips.
V 4780S2 - TAPPED STEP TRANSFORMER AUTOMATIC FOR VOLTAGE DIPS
The V 4780S2 is an automatic tapped auto transformer, designed to supply the required voltages as per IEC/EN 61000-4-11 to perform voltage dips and interruptions. Compared to the manually operated V 4780, the V 4780S2 model offers automatic change of taps according to the selected voltage level.
CNV 504/508 N- AND T-SERIES - SURGE COUPLING/DECOUPLING NETWORKS FOR SIGNAL/DATA LINES
CNV 504/508 N- and T-series coupling/decoupling networks are available to perform surge tests on I/O lines, signal/data lines and telecom lines as per IEC/EN 61000-4-5 Ed 3.0
ACCESSORIES
MS 100N - MAGNETIC FIELD COIL FOR POWER-FREQUENCY AND PULSED MAGNETIC FIELDS
The MS 100N is a 1m x 1m magnetic field coil as specified in IEC/EN 61000-4-8 and IEC/EN 61000-4-9. Its design allows easy moving of the coil. The field coil is adjustable in height and allows for 360 degree rotation. To generate power-frequency magnetic fields in the lower range the current transformer MFT 30 is used while high-field strength above 100 A/m up to 1000 A/m requires the MFT 100 current transformer.
CCI - CAPACITIVE COUPLING CLAMP
Capacitive coupling clamp as per specification IEC/EN 61000-4-4.
ITP - IMMUNITY TEST PROBES
ITP is a tool being used for development test. It consists of a variety of electrical field probes. The probes allow to locate weak points within a system or on a PCB. The burst pulse is used to generate the disturbance signal.
PVF BKIT 1 - VERIFICATION KIT FOR EFT/BURST PULSES
As per IEC/EN 61000-4-4 the characteristic of the burst generator needs to be verified with two different loads, 50 ohm and 1,000 ohm. EM TEST offers a calibration kit consisting of the two loads and an adapter to verify the pulses at the EUT output.
CCI PVKIT 1 - VERIFICATION KIT FOR CAPACITIVE COUPLING CLAMP
The IEC/EN 61000-4-4 Ed 3.0 standard published in 2012 recommends the calibration of the capacitive coupling clamp into a 50 ohm coaxial load. The capacitive coupling clamp (CCI or HFK) is connected to the 50 ohm output of the EFT generator. A flexible insulated plate inside the capacitive coupling clamp is connected to a coaxial 50 ohm load resistor for verifying the EFT/Burst wave of the capacitive coupling clamp.
