Product Description Product DescriptionZGF series DC high voltage generator is a new generation of portable high voltage testinginstruments designed and manufactured according to the latest electric power industry standards,specially used to test the electrical insulation strength and leakage current of electric power devices.This instrument adopts a high-frequency multiplier circuit,applying the latest PWM pulse widthmodulation technology and voltage-current dual closed-loop feedback technology to improvepower supply adjustment rate and load adjustment rate,ensuring high voltage stability and lowripple.It utilizes high-power IGBT devices and their driving technology,eliminating switchinterference and achieving high quality and portability of the DC high voltage generator.Importedhigh-frequency high-voltage rectifier diodes are used to make the multiplier compact andlightweight,enhancing overall efficiency.Based on EMI electromagnetic interference and EMCelectromagnetic compatibility theory,the instrument incorporates shielding,isolation,andgrounding measures to enhance overall safety,capable of withstanding rated voltage dischargewithout damage.The instrument is equipped with comprehensive protection functions includingzero position protection,over-voltage protection,over-current protection,and breakdownprotection,employing nanosecond-level dedicated sensors for swift and reliable operation,effectively ensuring personal and equipment safety.Over-voltage setting uses digital DIP switchesfor simple operation and high setting precision.The addition of the intelligent high-precision 0.75Ufunction button facilitates testing of zinc oxide surge arresters.Product Features1. Stable Output Voltage:Adopts high-frequency multipliercircuit,PWM pulse width modulation technology,andvoltage-current dual closed-loop feedback technology forhigh power supply adjustment rate and low ripple.Smoothvoltage adjustment over the full range with high outputvoltage accuracy.The main unit voltmeter directly displaysthe voltage loaded on the load without requiring externaldivider,simplifying wiring operation.Voltage resolution is 0.1 kV,current resolution is 1uA.2. Comprehensive Protection:Fully equipped withprotection functions including zero position protection,overvoltage protection,overcurrent protection,andbreakdown protection.Protection circuits use nanosecond-level dedicated sensors for swift and reliable operation,effectively ensuring personal and equipment safety.3. 0.75U Function:Added intelligent high-precision 0.75Ufunction button.Pressing this buttonautomatically adjusts voltage and current to 0.75U state,facilitating testing of zinc oxide surgearresters.4. Zero Start Boost:Boosting potentiometer zero start boosting,using imported multi-turnpotentiometer for smooth boosting process and high adjustment accuracy.5. Over-voltage Setting:Over-voltage setting uses digital DIP switches for simple operation andhigh setting precision.6. Integrated Design:Utilizes an integrated design where the main unit and multiplier are housed ina single chassis.Imported high-frequency high-voltage rectifier diodesmake the multipliercompact,enhancing overall efficiency and portability.7. Reliable Performance:Key components use high-performance imported devices,with themultiplier coated with special insulation materials on the outside,providing good electricalperformance,strong moisture resistance,and no leakage.8. Easy Operation:Instrument interface with logically arranged function keys,clear indicators,easyto learn and use.Detailed PhotosProduct Parameters SpecificationsTechnical Parameters60/2/3/5120/2/3/5200/2/3/5300/2/3/5Rated Voltage (kV)60120200300Rated Current(mA)2/3/52/3/52/3/52/3/5Rated Power(W)120/180/300240/360/600400/600/1000600/900/1500Control Box Weight(kg)4.54.54.54.5Multiplier Weight (kg)4.54.52227Multiplier Height(mm)4405409701220Voltage Accuracy±(1.0%reading + 1 digit)Current Accuracy±(1.0%reading + 1 digit)Ripple Factor≤0.2%Voltage Stability≤1% when power supply voltage varies ±10%Overload CapacityNo-load voltage can exceed rated voltage by 10% for 10 minutes Maximum charging current is 1.25 times rated currentPower SupplySingle-phase AC 50Hz 220V ±10%Operating Mode Intermittent use: rated load for 30 minutes1.1 times rated voltage use: 10 minutesOperating Environment Temperature: -10°C to +40°CRelative Humidity: ≤85% at 25°C (non-condensing)Altitude: Below 1500 metersLoad Capacity with CapacitanceUndefined limit on specimen capacitanceControl Box FeaturesCan charge up to 1.5 times rated currentFully automatic testing of zinc oxide surge arrestersManual voltage output adjustment function included.Product DimensionCompany ProfileSimilar RecommendationFAQQ1:Is your company a sales or a manufacturer?
