I. Product Overview

This instrument can detect technical indicators such as the insulation structure or insulation strength of the tested instruments and electrical appliances, and is widely used in electrical equipment, electrical instruments, transformers, power cords, watt-hour meters, motors, power plug sockets, cables, etc. Withstand voltage testing provides testing methods for the implementation of national safety standards, thus showing its importance and becoming indispensable for scientific research institutions, measurement and testing departments and the power and electronic industries to detect electrical devices, electronic instruments and household appliances. equipment.

The instrument has a beautiful appearance and the output voltage is displayed by a digital tube, which is clear, intuitive and accurate. Each parameter setting is entered using the small keyboard, which is easy to operate. The whole machine has advanced technology, reasonable layout, high accuracy, good reliability and convenient maintenance.

The instrument adopts an integrated design integrating control box and test voltage. The current protection is adjusted by the dial, which is small in size and light in weight. Known as a small AC and DC booster, it is a basic test equipment for users such as power stations, power supply and distribution systems, and scientific research institutions. It is used to conduct dielectric strength tests under specified voltage on various electrical products, electrical components, insulating materials, etc. Assess the insulation level of the product, discover the insulation defects of the tested product, and measure the ability to withstand overvoltage.

II. Product Performance Features

1. The AC withstand voltage of the instrument can be increased up to 3KV/AC, 0.33A/AC

2. The whole machine adopts a portable design of aluminum alloy chassis, which has strong anti-interference ability, compact structure and exquisite appearance. It solves the problem of places where the capacity requirement is not high and DC withstand voltage test is required.

3. The instrument uses a digital dial for timing, which effectively protects the test object from damage due to accidental breakdown. It also has a time setting, which can be used in insulation and voltage-resistant situations that require time.

4. The unique distribution of voltage and ammeter makes it clear to the operator at a glance.

IV. How To Use The Product

1. First, connect the test wires between the output high-voltage test products, and at the same time connect the ground with bare copper wires of more than 2.5 square meters to ensure personal safety, set the current, and boost the voltage after setting the current and exceeding the rated current. Will protect.

2. The time is set by dialing the dial (the dialing switch is in units of 0 seconds and 10 seconds from right to left, such as "10" seconds showing "1" and "0"). The longest setting is 99 seconds. During the test It should be set before. At this time, the timing switch cannot be pressed, otherwise the set time will be incorrect.

3. After confirming that the wiring is correct, plug in the power and turn on the power switch. At this time, the power indicator light (green) is on and the zero indicator light (yellow) is on. If the zero indicator light is not on, please return the voltage regulator to zero.

4. After the yellow light is on, approach the "Start" button. At this time, the output indicator light (red) is on. If it is not on, please press the "Stop/Reset" button, and then press the "Start" button.

5. After the red light is on, the voltage can be started to increase. At this time, strict attention should be paid to the high voltage voltage and current. When the rated test voltage reaches the rated test voltage, press the timing switch. The timing starts and the output high voltage will be automatically disconnected after the set time. If the high voltage and current suddenly return to zero during boosting, it means that the test product has broken down or the set current is too low to cause overcurrent protection.

6. After the time is up, please adjust the voltage regulator to the "zero position". After the entire test is completed, turn off the power switch.

V. Product Usage Environment

1. Ambient temperature: 0～40℃

2. Altitude: <1000m

3. Relative humidity: <85%

4. The workplace should be free of chemical dust and explosive media that seriously affect insulation.
