N4L Newtons4th Ltd Compliant Testing In Accordance with: IEC/EN61000-3-2 IEC/EN61000-3-3 IEC/EN61000-3-11 IEC/EN61000-3-12 N4A DC+AC Power Sources N4A03 - 3kVA Single Phase N4A06 - 6kVA Single Phase N4A18 - 18kVA Three Phase N4A30 - 30kVA Three Phase N4A67 - 67kVA Three Phase DC+AC Output DC-1kHz (10kHz small signal bandwidth) Single Phase and 3 Phase Single Phase and 3 Phase systems available Market Leading Inrush 2x Continuous Output for 3 seconds Fast Switch on Time Proprietary Design Versatile interfaces Arbitrary Waveform Custom Arbitrary Waveform, Sequencing and More Stored in Hardware for Fast Recall High Efficiency Compact Design High Power Density

The N4A range of Programmable AC Power Sources offer complete flexibility for a wide range of applications. All N4A sources feature dual channel arbitrary waveform generators utilising direct digital synthesis providing the user with simultaneous multiple harmonic generation, frequency sweeping and long sequencing capabilities. The metrology of the arbitrary generator permits long custom waveform sequences to be produced without a reduction in the resolution of each individual waveform. The N4A AC Source also features 10 bit vertical resolution and a maximum waveform resolution of 16,384...

■ Low THD equivalent to Linear Power Sources N4A Advanced Power Amplifiers feature proprietary noise suppression analgoue electronics known as "6 leg modulation" topology which produces an output waveform during high loads with less than 0.1% THD. This level of distortion has only previously been possible with linear power sources. Due to modern developments in amplifier design we can now offer excellent distortion in a smaller package, with higher efficiency. The ability to generate DC+AC at a lower cost than the equivalent Linear Amplifiers on the market is a breakthrough in power source...

■ N4A PCU (Programmable Controller Unit) The N4A PCU provides a wide range of output waveforms, from Harmonic synthesis to waveform sequencing. The N4A range of Advanced AC Power Sources are available with single phase (N4A03 + N4A06) and three phase (N4A18, N4A30 + N4A67) outputs. The N4A Advanced AC+DC Power Source provides real time monitoring of the output voltage and current on each phase. For the highest of power measurement accuracy and market leading harmonic analysis our Precision Power analyzer range offers an excellent measurement solution in combination with the N4A Power...

■ Rapid Switch on Times Due to an innovative "6 leg" output topology the N4A Advanced Power Amplifiers offer rapid switch on times as seen in the oscilloscope screenshot below. Rapid Switch on Times ■ IEC61000-3-2/12 and IEC61000-3-3/11 Harmonics and Flicker N4A Advanced AC Power Sources offer full compliance to IEC61000-3-2/12 and IEC61000-3-3/11 (N4A06/18/30/67). Featuring very low distortion (<0.1% THD typical) and very low output impedance, the N4A range of power amplifiers can be supplied as a stand alone AC power source to be integrated into another test system or as a standalone...

■ 3 Phase AC Power Sources up to 67kVA N4A Advanced AC Power Sources are available in 3 phase configurations as well as single phase configuration. Three phase systems feature a master unit (N4A18-M pictured below) and two slave units (N4A18-S pictured below), the N4A three phase configurations offer a convenient solution when servicing is required as only the master and slave units themselves need to be shipped, offering significant savings on shipment costs. All N4A three phase systems feature fully isolated outputs, very low harmonic distortion even under heavy load and the ability to...
