GW INSTEK ASR-2000 Series Programmable AC/DC Power Source

The GWINSTEK ASR-2000 series, is a AC+DC power source aiming for system integration or desktop applications, provides both rated power output for AC output and rated power output for DC output.

Nine ASR-2000 output modes are available, including
1) AC power output mode (AC-INT Mode),
2) DC power output mode (DC-INT Mode),
3) AC/DC power output mode (AC+DC-INT Mode),
4) External AC signal source mode (AC-EXT Mode),
5) External AC/DC signal source mode (AC+DC-EXT Mode),
6) External AC signal superposition mode (AC-ADD Mode),
7) External AC/DC signal superposition mode (AC+DC-ADD Mode),
8) External AC signal synchronization mode (AC-SYNC Mode),
9) External AC/DC signal synchronization mode (AC+DC-SYNC Mode).

The GW INSTEK ASR-2000 series provides users with waveform output capabilities to meet the test requirements of different electronic component development, automotive electrical devices and home appliance, including 1) Sequence mode generates waveform fallings, surges, sags, changes and other abnormal power line conditions; 2) Arbitrary waveform function allows users to store/upload user-defined waveforms; and 3) Simulate mode simulates power outage, voltage rise, voltage fall, and frequency variations.

When the ASR-2000 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 sense function ensures accurate voltage output. The Customized Phase Angle for Output On/Off function can set the starting angle and ending angle of the voltage output according to the test requirements. V-Limit, Ipeak-Limit, F-Limit, OVP, OCP, OPP function settings can protect the DUT during the measurement process. In addition to OTP, OCP, and OPP protection, the ASR-2000 series also incorporates the Fan fail alarm function and AC fail alarm function.
