300 VA AC Source with Power Line Disturbance Simulator

30 April 2015 - B&K Precision introduced a new AC power source, the model 9801, expanding its AC power supply offerings. This compact 19" half-rack single-phase AC source outputs up to 300 VA and measures AC power characteristics. Users can operate the AC source in a 0-300 V continuous sweep range or 150 V/300 V auto-switching range with adjustable start and stop phase angle control. With a built-in power line disturbance (PLD) simulator, list, sweep, and dimmer mode, the 9801 is suitable for simulating various AC power conditions and provides a complete solution for manufacturing, R&D, and pre-compliance testing applications.

For certain compliance testing applications, manufacturers may need an AC source to simulate various AC power line outlets and disturbances. This includes evaluating a product's immunity to less than ideal input voltage situations such as dips, surges, and dropouts. Therefore, programmable AC sources with built-in power line disturbance simulation functions can be an invaluable tool for testing devices under these conditions.

The 9801 features a low distortion, single-phase AC output with programmable RMS voltage up to 300 V, maximum RMS current up to 3 A, and adjustable frequency from 45 Hz to 500 Hz. The power source is also capable of delivering up to 12 A peak current.

Provided on the front panel is a universal AC output socket and an easy-to-use rotary knob to set AC waveform parameters. The bright VFD display continuously displays the output voltage, peak and RMS current, frequency, power factor, apparent/true power, and elapsed time. The rear includes an additional AC output terminal block for wire connection and an external BNC connector for output On/Off control and monitoring, external triggering, and synchronization. Users will also benefit from the 9801's standard RS232, USBTMC-compliant USB, and LAN interfaces for remote control and programming.

Built-in simulation functions include list mode with PLD simulator, sweep, and phase-cut dimming output. The simulation modes allow users to program varying steps of voltage, frequency, width, slope, and disturbances, sweep the output voltage and frequency, and control the phase cut-off of the AC sine wave's leading or trailing edge. For pre-compliance testing, voltage fluctuations and frequency simulations can be set up according to IEC61000-4-11, IEC61000-4-14, and IEC61000-4-28.

Furthermore, the 9801 provides several protection features: overvoltage (OVP), overcurrent (OCP), overpower (OPP), and overtemperature (OTP) protection, settable voltage and frequency limits, key lock function, and RMS/peak current protection settings to shut off the output when a load exceeds the set current.

Available immediately, B&K Precision's 9801 AC power source comes with a two-year warranty and lists at a price of $1,995.
