Model : VDS-2002 Conforming to IEC Pub. 61000-4-11   개요 전력선 계통의 문제에 의한 순간정전, 순간적 전압변동에 대한 회복은 빨라도 0.07초의 시간이 필요하고, 이 70mS라는 시간은 마이크로 프로세서가 내장된 전자기기에 영향을 주기에 충분한 시간입니다. 또한 하나의 전원에서 여러 가지 전기, 전자기기를 동시에 사용할 때 다양한 전압 변동 현상이 발생하여 전자기기에 영향을 미치게 되며, 이러한 이유로 오래 전부터 전원에서 발생되는 전압 변동에 대한 Immunity를 시험 할 수 있는 Voltage Dip & Up 시험기가 사용되어졌다. 현재에 이르러서는 이러한 전압변동에 관련한 Immunity시험을 국제규격인 IEC pub. 61000-4-11 (EN 61000-4-11)에서 채택하고 있으며, VDS-2002는 완전 100% 규격 대응 장비로서, 순단시의 Rising & Falling Time, 1 ∼5㎲로 설계되었고, 사용자의 조작성을 위하여 PC Control에 의한 자동 시험이 가능하다.   특징 - EN/IEC61000-4-11 완전 대응 시험기. - 전세계 Plug Type에 맞는 멀티콘센트 사용. - DC 순단시험 가능. - PC 제어가 가능     Option - SOFTWARE, ENGLISH, 14-00036A - OPTO LINK SET RS-232C용, 07-00017A - USB OPTICAL MODULE KIT, 07-00022A     Spec Parameters Specifications Remarks Compliant standard IEC 61000-4-11 Number of lines Single phase Test mode Interruption AC/DC Synchronous PC/local Short circuit Asynchronous PC Synchronous/Asyn chronous PC Open circuit Dip and swell Synchronous PC/local Asynchronous PC Variation Asynchronous PC/Local Only 2s-1s-2s standard defined test available in local mode Input voltage range AC90~264V, 50/60 Hz DC0~125V Output voltage range AC0V~120% of input voltage DC0V~input voltage AC290V max Output VA 4.224kVA Continuous Output current capability AC 100% of input voltage 16A rms Continuous 70% of input voltage 23A rms <5S 40% of input voltage 40A rms <5S DC 16A Continuous Peak inrush current drive capability AC100~120V >250A at 100% output, <10ms AC220~240V < 500A Load regulation 100% of input voltage 0~16A rms <5% 70% of input voltage 0~23A rms <7% 100% of input voltage 0~40A rms <10% Overshoot/undershoot <5% 100 ohm loaded Rise time/fall time 1~5㎲ 100 ohm loaded Normal voltage setting Setting by percent PC ~120% 10V minimum Local 100% Setting by voltage PC 10V~290V 5V step Accuraey ±5V 0V~16A output Dip/Swell level Setting by percent PC Short/Open selectable for 0% (interruption) 0~120% Local Short circuit for 0% (interruption) setting 0/40/70/120% 4 steps Setting by voltage PC Short/Open selectable for 0V (interruption) 0~290V(0~120%) 5V step Accuraey ±5V Repetition of events No. of events PC 1~1000 or continuous 1 event step Local 1, 3, 5, 10, 30, 50, 100 or continuous 8 steps Interval cycle Setting by cycle Synchronous PC 0.5~5000.5 cycles 0.5 cycle step Local 1,3,5,10,30,50,100,300,500 cycles, 10s 10 steps Setting for short duration Synchronous PC 1~100s 1s step Asynchronous 10ms~100s (50Hz) 8.3ms~100s (60Hz) 0.1 ms step Setting by time Setting for long duration Asynchronous 1s~10h 1s step Dip cycle Setting by cycle Synchronous PC 0.01~5000 cycles 0.01 cycle step Local 0.5, 1, 5, 10, 25, 50 cycles 6 steps Setting by time Setting for short duration Synchronous PC 0.1 ms~100s 0.1ms step Asynchronous 0.1 ms~100s 0.1ms step Setting for long duration Asynchronous 1s~10h 1s step Dip phase (Starting phase angle of events) Setting by phase angle Synchronous PC 0˚~359˚ 1 step Local 0, 45, 90, 135, 180, 225, 270, 315 8 steps (45 degrees step) Setting by time PC 0~19.9 ms for 50Hz 0.1ms step 0~19.9 ms for 60Hz Voltage variation test Setting by time Changing time Asynchronous PC 0.1s~10 s at least 0.1s required for 10% change of input 0.1s step Changed time 0~10s Interval 0~100s 0.1s step Test level PC 0~120% 0.1s step Memory Local 5 tests Test sequence stored up to 10 steps when controlled by PC PC 10 steps Equipment input AC100~115V/200~240V 10%, 50/60Hz, 120VA External interface optical RS-232 Operating temperature 15~35 ℃ Operating humidity 25~75%R.H.
