Product introduction

NRNY series intelligent power frequency withstand voltage control box is designed based on the latest national industry standard, its safe, reliable, powerful, easy to use, easy to maintenance, mainly used for a variety of electrical products, electrical components, insulation materials etc. Under the specified voltage to test the insulative strength, to asses the insulation level, then find the defective product and measure the ability of over voltage, is the preferred product for  relevant electrical departments, electrical appliances manufacturing enterprises, metallurgy, coal, railway electrification relevant departments, research institutes and universities, and other relative department.

Alternative name

Automatic power frequency withstand voltage control (box) sets, power frequency withstand voltage control desk, automatic power frequency withstand voltage control box, power frequency withstand voltage control box

The Characteristics of the products

● Voltage, current, time, status information and prompt message will be displayed on the 4.7 inch large LCD screen, with clear reading and intuitive ;
● Chinese interface, simple to operate, can be adapted to a variety of applications ;
● Touch button operation, all functions can be set via buttons, improved the safety and reliability ;
● Full digital calibration methods, abandoned the old potentiometer adjustment, extremely easy to use on-site, easy to control accuracy ( this function with password protection ) ;
● Key set the test transformer turns ratio directly ( this function with password protection ) , when connected with different voltage levels tester, the application is flexible and comfortable, just one control box, but can be matched with multiple transformers.
● Status notification function, with whole Chinese guided operation , can skill operate even without manual instruction;
● During the test , the screen with a flashing high voltage symbol, to notice the operator safety;
● With test results displayed function, can automatically determine the test results ( test pass or  test fail) , and reliable record of the tested object over current , flash or breakdown voltage ;
● Sound alarm the test results, test passed or fail , the device will emit different alarm voice,  the operator can identify by the alarm sound test results directly;
● Pause function, automatic control, this function can be done at any point such as achieve boost or buck pause, the pause time can controlled by the operator flexibility, for observing the test status easily;
● Automatic timer function. Automatic control, when the voltage is increases to the set value automatically, the device start time automatically, when the timer is time out, it will show the testing results, the device automatically returns to the zero position ;
● Manual timer function , when manual control, the timer can be started manually , when the pressure the start, the device returns to zero ( only desktop devices have this function ) automatically;
● Manual control mode, this mode is similar to the traditional electric buck / boost mode , up / down control by the button, the device judge the upper / lower limit automatically, also with over-voltage protection ;
● Boost speed with intelligent control, when the voltage reaches to 80% of the target voltage , the boost speed will automatically slow down, when it reaches to 90% of the target voltage , the boost speed slowed further ;
●Adopting the hardware and software anti-jamming technology, with stable performance and strong anti-interference .

Product information
Precautions and equipment for your safety, please read the following operators: 
● The enclosure must be grounded during the testing.
● The irrelevant objects do not allow to stack on and around the device panel.
● Check the power supply before starting voltage: AC 220V ± 10%    50Hz.
● When replace the fuse and accessories, please use the same type of the instrument.
● NRNY series intelligent power withstand voltage testing device should be prevented against moisture and grease.
● Before testing, please make sure the tested objects is power off, and disconnect the charged device.
