Source puts high-power equipment to the test

The NSG1007-45 is a programmable power source for testing and evaluating high power equipment and appliances.

The NSG1007-45 is a programmable power source for testing and evaluating high power equipment and appliances.

There is a growing requirement to fully test high power products over a wide range of input line conditions to ensure reliable operation and compliance to required standards.

The new NSG1007-45 power source offers a flexible and scaleable solution to these needs.

The NSG1007 is an easy to use integrated test system featuring built-in output transient generation and read-back capability.

Local programming is simply done from front panel controls incorporating an LCD display on which operating parameters are shown and measurements displayed.

Optional IEEE488 and RS232C interfaces are available with drivers for most popular ATE systems.

For advanced testing the programmable options include full arbitrary waveform generation, time and frequency domain measurements and current waveform capture.

45kVA of single or three-phase AC power is available from the standard NSG1007-45.

DC power is also supported using the programmable option.

For higher power testing, multicabinet multicontroller systems can up provide up to 135kVA of scaleable, very flexible systems testing.

Commonly required AC and DC measurement parameters are automatically provided by the onboard data-acquisition system and shown on the LCD.

These include: frequency, RMS voltage and current, peak current, crest factor, real power (W), apparent power (VA) and power factor.

Harmonic analysis is provided by detailed amplitude and phase information on up to fifty harmonics of the fundamental voltage and current for either one or three phases.

The harmonic content may be shown on the display or an embedded Windows GUI program may be used to display, save and print the data.

The waveform measurement system is based on real-time digitisation of the voltage and current waveforms using a 4Kbyte-deep sample buffer and provides time domain information recording information on both.

Data-acquisition can be triggered at a specific phase angle to allow precise positioning of the captured waveform with respect to the output of the AC source.

These results may also be displayed, saved and printed.

Andrew Kotas, Marketing Manager for Schaffner comments: "Functional testing of high power products to correctly measure power consumption and check their response to adverse line conditions such as brown-out have become an essential part of both new product development and final testing".

"Our new NSG1007-45 power source not only provides these important functions but will also allow rigorous harmonic measurement to IEC1000-4-11 and IEC1000-4-13 to ensure compliance with the Harmonics Directive".

For AC testing frequencies between 16 to 819Hz are available in either single or three-phase modes at power levels of 45, 90 and 135kVA.

Load regulation is better than 5%, line regulation better 1% and output noise less than 2%.

In DC output mode 10kW is available for three-phase testing and 30kW for single-phase.

Output ripple is less than 2V RMS.

The NSG1007-45 has constant current or constant current overload protection, over-temperature protection, remote shutdown and external synch.

The NSG1007-45 has a maximum weight of 600kg, is fitted with castors and forklift openings and has dimensions of 1270 x 731 x 876mm.

The NSG1007-45 also meets IEC61010, EN50081-2, EN50082-2 is CE marked for EMC and safety.
