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:
Model ASR-3200 ASR-3300 ASR-3400
Output Voltage 0~400Vrms/0~±570Vdc 0~400Vrms/0~±570Vdc 0~400Vrms/0~±570Vdc
Output Current 20/10A 30/15A 40/20A
Power Rating 2000VA 3000VA 4000VA
Output Frequency 1.00Hz ~ 999.9Hz 1.00Hz ~ 999.9Hz 1.00Hz ~ 999.9Hz
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.

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.

Sequence Mode and Built-In ISO-16750-2 Waveforms

The sequence mode provides 10 editable sets of SEQ0~SEQ9, each set has 0~999 steps, each step time setting range is 0.0001~999.9999 seconds. Users can combine multiple sets of steps to generate the required waveforms, including waveform falling, surges, sags, and other abnormal power line conditions to meet the needs of the test applications.
In addition, ASR-3000 Series also built in common ISO-16750-2 test waveforms in the Sequence Mode preset waveforms, including Momentary Drop in Supply Voltage built in at SEQ6, Reset Behavior at Voltage Drop with 12V system built in at SEQ7, Starting Profile Waveform built in at SEQ8 and Load Dump with Tr_10ms, and Td_40ms built in at SEQ9.
SEQ6: Momentary Drop in Supply Voltage
SEQ7: Reset Behavior at Voltage Drop with 12V System
SEQ8: Starting Profile Waveform
SEQ9: Load Dump with Tr_10ms, Td_40ms
Simulate Mode

Simulate Mode can quickly simulate different transient waveforms, such as power outage, voltage rise, and voltage fall. This enables engineers to evaluate the impact of transient phenomena on the DUT. Ex: Capacitance durability test.
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.
TRI Waveform
STAIR Waveform
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.
