RelayStar-502 Universal Relay Protection Tester

I.Features:

• Three-phase compatible single-phase There are 3 phase voltage outputs and 2 phase current outputs, which can reach AC120V/80VA and AC50A/450VA respectively.
• Intelligent type mainframe High-speed high-performance DSP is adopted, with fast calculation speed, broad transmission frequency band, which can generate 360 dots per cycle high-density fitting fundamental sine waves. This is the highest level among same class output mode.
• Waveform is with high fidelity and little distortion, especially for harmonic output, 60 dots per cycle high-density D/A output can be realized for 6^th (300Hz) harmonic.
• Independent operation Photoelectric rotary mouse and large LCD screen is installed on the panel for convenient operation, with total Chinesized interface. Fit for most verification test on-spot.
• Large LCD screen 320x240 lattice screen and high-definition graphical LCD are employed, with whole operation process displayed. Operation interface and test result are displayed in Chinese clearly and intuitively.
• Foolproof operation Advanced photoelectric rotary mouse is used, which largely simplifies operation structure and realizes convenient and easily-grasped operation.Instant and permanen t faults (such as single phase grounding, two-phase short-circuit)can be simulated factually.
• Various kinds of relays and microcomputer protection unit can be verified.
• Self-protection Not only reasonable heat dissipation structure,multiple perfect and reliable protection are also adopted, such as power soft-start, thermal protection,output time limit, current/voltage amplitude limit, voltage short circuit lockout, current open circuit indication, fault self-diagnosis and so on.
• Abundant contacts 7 channels input contacts and 2 couples free output contacts are available. Input contacts are compatible with free contacts and 0~250V potential contacts, with adaptive identification.
• Uniform structure with mainframe integrated The stand alone device is portable with dimension 400x370x140mm³ and weight 13kg, which is convenient for flow test.
• Power supply for the device is AC 220V. Operation is accessible right after device starts.
