Instek ASR-3300 – 3kVA Programmable AC/DC Power Source

The ASR-3000 series is an AC+DC power source, available in three varieties. The chart below provides a brief overview of the main features for each:

The ASR-3000 can provide rated power during both AC and DC output. The series offers nine output modes including:

• AC power output mode (AC-INT Mode)
• DC power output mode (DC-INT Mode)
• AC/DC power output mode (AC+DC-INT Mode)
• External AC signal source mode (AC-EXT Mode)
• External AC/DC signal source mode (AC+DC-EXT Mode)
• External AC signal superimposition mode (AC-ADD Mode)
• External AC/DC signal superimposition mode (AC+DC-ADD Mode)
• External AC signal synchronization mode (AC-SYNC Mode)
• External AC/DC signal synchronization mode (AC+DC-SYNC Mode)

The ASR-3000 provides users with several waveform output capabilities, including:

• Sequence mode – generates waveform fallings, surges, sags, changes and other abnormal power line conditions
• Arbitrary waveform function – allows users to store/upload user-defined waveforms
• Simulate mode – simulates power outage, voltage rise, voltage fall, and frequency variation

When the ASR3000 Series power source outputs, it can also measure Vrms, Vavg, Vpeak, Irms, Iavg, Ipeak, IpkH, P, S, Q, PF, CF, 40th-order Voltage Harmonic, and Current Harmonic. In addition, the remote sensing function ensures accurate voltage output, and the Customized Phase Angle for Output On/Off function can set the start and end angles of the voltage output according to the test requirements. The protection limits of V-Limit, Ipeak-Limit, and F-Limit can be set according to user requirements. Over voltage limit, OCP, OPP will protect the DUT during the output process. The Fan Fail Alarm function and the AC fail alarm function are also designed in the ASR3000 Series.

The front panel of the ASR-3000 Series provides a universal socket or a European socket, which allows users to plug and use so as to save wiring time. Since the power socket specification has a maximum current of 15A, the rear panel of ASR-3000 Series is designed with a current circuit breaker. When the socket current is greater than 15A, it will automatically open the circuit to protect users. The ASR-3000 Series supports I/O interface and is standardly equipped with USB, LAN, External I/O, RS-232C, and GPIB.

Operating Area

The graphs below show the AC and DC performance characteristics of the three models in the ASR-3000 series.

Measurement Features

The ASR-3000 Series provides users with measurement capabilities including Vrms, Vavg, Vpeak, Irms, Iavg, Ipeak, IpkH, P, S, Q, PF, CF, 40th-order Voltage Harmonic and Current Harmonic. During the power output, the measurement parameters including Vrms/Irms, Vavg/Iavg and Vmax/Vmin/ Imax/ Imin can be switched by users at any time to display the instantaneous calculation reading.

Function Waveform (Arbitrary Edit) Mode

The ASR-3000 provides more than 20,000 waveform combinations in seven categories, allowing users to quickly simulate different AC voltage waveforms. Adjust the desired waveform type directly through the panel (displayed synchronously on the screen), then the waveform is loaded into the ARB 1~16 waveform register through the access procedures. Return to the main menu output mode to perform ARB Waveform output.

Slew Rate Mode

The ASR-3000 can set the Slew Rate Mode to determine the rise time of the voltage according to the test requirements of the DUT. Slew Rate Mode provides “Time” and “Slope” modes. When setting “Time” mode, the ASR-3000 can increase output to 10~90% of the set voltage within 100µs; and when selecting “Slope” mode, the ASR-3000 increases output voltage by a fixed rising slope of 1.5V/µs until reaching μ the set voltage value.

In addition, if users decide to self-define the rise time of the output voltage, users can flexibly set the rise time of the voltage by editing the Sequence mode.
