TQSB Portable High Voltage Test Transformer Price, also known as a booster, is a basic test equipment for power stations, power supply and distribution systems, and scientific research institutions. It is used for insulation strength tests at specified voltages on various electrical products, electrical equipment, and insulating materials, to assess the insulation level of products, detect insulation defects in test objects, and measure their ability to withstand overvoltages.



II. Product Features:



1. Monitoring functions: output current   instrument voltage  zero position indication   open/close indication  timing indication



2. Protection functions: overcurrent protection   time relay



3. TQSB Portable High Voltage Test Transformer Price adopts a new type of time relay, with a wider timing range.



4. Adopts a new type of current relay, which is more accurate and reliable, ensuring the safety of personnel and equipment.



5. Reasonable structure, small size, and light weight.



III. Technical Specifications:



1. Input voltage: 220V±10%    50HZ



2. Output voltage: 0-250V



3. Output capacity: 3KVA



4. Timing range: 1S-99H



5. Ambient temperature: -20°C to     50°C



IV. Usage Instructions:



1. Connect wires correctly, and turn the voltage regulator counterclockwise back to zero. (Voltage cannot be increased if the regulator is not at zero)



2. According to test requirements, set the "time relay" and "current relay".



3. Plug in the power cord, the power indicator lights up, press the close button, and the power-on indicator lights up. (Now voltage can be increased)



4. Rotate the voltage regulator handle clockwise at a uniform speed to the required value.



5. Start the timing switch, and when the "timing buzzer alarm" sounds, it indicates that the time is up.



6. Turn the voltage regulator counterclockwise to zero, press the open button, and the power-on indicator goes out.



7. Unplug the power cord and remove the wiring, the power indicator goes out, and the test is completed.



V. Precautions:



1. During use, this instrument should be reliably grounded.



2. The voltage increase and decrease process should be uniform, not suddenly fast or slow.



3. During the test, the monitoring instruments should be observed at all times to detect unexpected situations in a timely manner.
