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 6th (300Hz) harmonic.
Independentoperation 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 operationAdvanced photoelectric rotary mouse
is used, which largely simplifies operation structure and realizesconvenient 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-protectionNot only reasonable heat dissipation structure,multiple perfect and reliable protection are also adopted,
suchas 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 contacts7 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.
II.Functions
The device can not only test the protection of all kinds of relays (such as current, voltage, normal inverse, power direction, impedance,differential, low-cycle,
synchronization, frequency, direct current, auxiliary and time) and microcomputer protection units, but can also simulate temporary, permanent and conversion faults from single-phase to three-phase for group test.
Operation is accessible right after switching on, which is convenient
and speedy.
