Two,Key Technical Parameters Features
1Technical Features:
The case is made of aluminum alloy.
● Utilizing a medium-frequency step-up circuit, appliedPWMPulse Width Modulation (PWM) technology and high-powerIGBTComponents.
● Utilizes high voltage feedback for stable output voltage with a ripple coefficient ≤ 0.5%。
Full-range smooth pressure regulation, good voltage regulation accuracy, adjustment accuracy ≤0.5%, Stability ≤1%± (1)%±2 characters), current error ±(1)%±2 characters).
● Zero-start step-up potentiometer.
● 0.75UDC1mAFunction buttons for convenient zinc oxide arrester testing, accuracy±（1.0%±2 characters).
● Overvoltage protection uses a pin code setting, clear at a glance, ±1 error%。
● The super-pressure design utilizes new materials, offering both lightness and durability. The surface is coated with a special insulating material, ensuring excellent electrical properties and strong moisture resistance.
● ZGF products meet the technical requirements of DL/T848.1-2004 and have passed the type test by the Electrical Equipment Quality Inspection and Testing Center of the Ministry of Power, strictly adhering to the corporate standards for production.
