N4A series three-phase AC power supplies

The N4A series of three-phase AC power supplies from Newtons4th consists of three programmable 3-phase AC power supplies with a capacity of 18 kVA, 30 kVA and 67 kVA. The N4A series has a so-called directly coupled output stage, which also makes it possible to generate DC or AC+DC output voltage. A striking feature is the fact that this series can deliver maximum power for 3 seconds to twice the maximum output.

This inrush current capacity makes it possible to still start up large motors, compressors or other equipment with a lower power AC supply, where the initial current is often significantly higher than the rated current.

The fundamental frequency is adjustable from 15Hz to 1000Hz, with the bandwidth for small signals reaching 10kHz. The output voltage is adjustable from 0-300Vrms (L-N). In DC mode, this equals 0-424Vdc.

Operation of the power supply can be controlled manually or remotely via the standard RS232, USB or LAN interface.

Extensive software is included free of charge.

Harmonics and Flicker testing according to IEC standards?

Distinctive for the Newtons4th’ N4A series three-phase AC power supplies is the ability to deliberately simulate disruptions and deformations using a built-in arbitrary function generator. In addition to the standard grid contamination in the form of interrupts and dips, it is also possible to generate harmonic distortion. A combination with the Newtons4th PPA5531 power analyzers and an IMPxx3 impedance network, these power supplies are suitable for compliance testing for Harmonics according to IEC 61000-3-2, Flicker according to IEC 61000-3-3-3 and immunity tests according to IEC 61000-4-7/-15.

With the combination with the free software you will then have a complete compliant test solution for these standards.

The N4A Series of Newtons4th consists of the following models:

  • N4A18,18,18 kVA three-phase
  • N4A30,30 kVA three-phase
  • N4A67,67 kVA three-phase

Newtons4th also carries single-phase AC power supplies in their product line.
