Overview Microcomputer relay protection tester also known as three-phase microcomputer relay protection tester, three-phase microcomputer relay protection tester is a special power relay protection tester.Three-phase microcomputer relay protection tester has 4 phase voltage 3 phase current output, suitable for various types of relay protection device test.Three-phase microcomputer relay protection tester adopts high speed and high performance digital control processor as control microcomputer, and the software uses double precision algorithm to generate arbitrary high precision waveform of each phase.Because of the integrated structure, each part is closely combined, the data transmission distance is short, and the structure is compact.It overcomes the problem of low number of output waveform points caused by long data communication line and narrow frequency band in the measurement and control instrument directly controlled by laptop computer. Technical parameter : AC current output Output accuracy Phase current output (effective value) Three merge current output (effective value) 120A Phase electric length time allows work value (effective value) 10A Phase current maximum output power 420VA Maximum output power at the maximum output of three 900VA Working time is allowed when the maximum output of the three mesh is output 10s Frequency range (fundamental) 20 1000Hz Harmonics 1 20 times AC voltage output Output accuracy Level 0.2 Phase voltage output valid value 120V Line voltage output valid value 210V Maximum voltage output value 240V Phase voltage / line voltage output power 80VA /100VA Frequency range (fundamental) 20 1000Hz Harmonics 1 20 times
Digital event counter - totaliser manufactured by fabrotech is useful as object or pulse counter in different process and industries. By setting a multiplying factor (0.00001 to 999999) it can be used for displaying the linear measurement such as total length in meters or cms. Input pulse can be from proximity switch, infra red sensor, voltage pulse or no-contact of a switch. It can be reset by front switch or from rear terminal. 6 digit 0.56÷height bright red led's display the count. Optionally this 6 digit counter can be used as low cost, compact 11 digit counter. In case of power failure, the display count is retained in memory without any battery. The power consumption is less than 5 watts. Operating supply voltage is 230 v ac + 10%, 50hz. Housed in enclosure of din size 48(h) x 96(w) x 110(d)mm. Each, 600gms, 96x48mm
