Programmable Auto Safety Tester

Standard PLC interface, optional ports: RS232C, RS485, GPIB, USB Calibration and prompt function, after twelve-month use, tester can automatically give the prompt information Test results which maximum can be up to 9999 will be stored into the instrument or sent to PC through RS232 interface Adopt 240*64 graphic dot-matrix LCD, displaying setting parameters and testing parameters strikingly, visually LCD contrast, buzzer volume, retention time of PASS signal can be adjusted by keystrokes Users can name the memory groups as required freely, which maximum can be up to 14 User friendly, support both Chinese and English, simple and convenient operation The tester will first check whether the input power supply right connected to N, L, G Output voltage with out of tolerance auto-detection function, when error between actual output voltage and setting voltage exceeds5%±5V, the tester will alarm with out of tolerance of voltage after testing Automatic detection whether operators touched hi-pot probe, upon hi-pot probe is touched, the tester can’t be performed Key lock, preventing operators from modifying testing parameters Optional output voltage modes: Normal mode and Step mode. Normal mode is that tester automatically stops hi-pot output when test time is out; Step mode is according to users’ setting value, tester automatically will switch to second-step voltage output on the first-step voltage when test time is out. Measuring terminal can choose grounding connection mode or float grounding mode Users can perform single-step test or multi-step consecutive test with any procedure Real current capable of measuring capacitive load Rectification circuit adopts RMS-DC converter, truly reflecting test’s output voltage and measured current value DC and insulation test with RAMP-HI and CHARGE-LO function Stabilized voltage output with the stability of 1% with linear power amplifier . The tester satisfies the safety regulation criterion, which requires the crest factor must be in a range between 1.3 and 1.5 0.2s quick discharge after DC withstanding voltage testing and 0.4ms quick cut-off after AC withstanding voltage testing In AC withstanding voltage testing, Output voltage is within a frequency between 40.0 400.0Hz.(at a resolution of 0.1Hz), Which can satisfy different customers with various requirements Withstanding VoltageModelOutput voltageAccuracyTest currentAccuracyTest timeCS9933(0.050—5/6)kV(AC/DC)±(1%+2counts)(0—20.00/10.00)mA(AC/DC)±(1%+2counts)(0.3—999.9) sCS9921A(0.050—5/6)kV (AC/DC)±(1%+2counts)(0—20.00)mA(AC/DC)±(1%+2counts)(0.3—999.9) sInsulation ResistanceGround ResistanceModelOutput voltageResistance rangeTest timeOutput currentTest rangeAccuracyTest timeCS9933(0.050-1)KV 0-9999MΩ(0.3—999.9) s (3-30)A1-510mΩ±(1%+2counts)(0.3—999.9) sCS9921A(3-30)A1-510mΩ±(1%+2counts)(0.3—999.9) s
