Programmable AC power supply features amplifier mode

Delivering up to 3000VA and featuring an operating frequency to 1200Hz, the 9830 series builds on B&K Precision’s widely deployed family of AC power sources, giving designers a more versatile test instrument for developing products requiring a wider range of power. 

The 9830 series - model 9832 with AC power of 2000VA, and model 9833 with 3000VA - are designed for R&D laboratories, service centres and manufacturing applications. The 9832 and 9833 deliver highly accurate sine output with low Total Harmonic Distortion (THD) when operating in AC output mode. Their built-in output options include sine, square, clip-sine, harmonic distortion and user-defined waveforms. The competitively priced 9832 and 9833 each feature an amplifier mode with 1.2kHz bandwidth for generating complex arbitrary waveforms.

“Power requirements vary widely by region and country, so we designed the new 9830 series to allow development of a broad range of AC power products for the global market,” said David Holt, Senior Product Manager at B&K Precision. “These new AC power sources deliver a compact yet feature rich and cost effective solution that can meet designers’ current and future output power and frequency needs, while enabling pre-compliance testing in accordance with international standards.” The 9832 and 9833 can be used to simulate power line disturbances and worldwide power requirements. Additionally, their 12 on-screen measurements provide detailed information about the device under test. The instruments’ AC+DC mode can be used to provide DC bias voltage and is also useful for power line disturbance testing.

The 9830 series increases the VA range of B&K Precision’s earlier AC power sources by up to 200% and extends the operating frequency to 1200Hz. Both instruments support remote-interface standards common in system designs: LAN, GPIB, USBTMC-compliant USB, and RS232.

The 9830 series’ intuitive user interface features a numeric keypad, rotary knob, navigation keys, a 4.3" colour LCD display capable of displaying 12 measurements simultaneously, and a USB host port. The instruments can also be controlled from a standard web browser via built-in web server.
