HV Hipot Electric Co., Ltd. specializes in producing series resonance (also known as series resonance withstand voltage equipment). Next, we will share with you the characteristics of series resonance withstand voltage equipment.
1. The main controller of the variable frequency power supply uses a 320 × 240 dot matrix LCD display screen (with backlight), with high resolution and clear fonts. It can be easily seen both indoors and outdoors under strong and weak lighting conditions.
2. The experimental data can be saved on the screen and accessed freely, with a computer interface that can be connected to an external printer for printing. Imported chassis and stainless steel panel are selected, with buttons integrated with the panel for a beautiful appearance.
3. Three operation modes
(1) Automatic tuning, manual boosting
(2) Manual tuning, manual boost
(3) Automatic tuning, automatic boost
4. The comprehensive protection function includes multiple protections such as zero position, overcurrent, overvoltage, overheating, and high-voltage flashover. When the protection function is activated, the screen displays in Chinese; When the device operates at rated voltage and current, high-voltage flashover or breakdown will occur without damaging the entire equipment, and the device can work normally; If the device wiring is incorrect, the high voltage will automatically lock and cannot be boosted.
(1) Automatic zero start protection
(2) Overvoltage protection – built-in automatic overvoltage protection, can manually set the test voltage value, and automatically cut off the entire device when the voltage reaches 1.1 times the test voltage. (For some products)
(3) Overcurrent protection – built-in automatic current protection, automatically cuts off the entire device when the current exceeds 1.1 times the rated value
(4) High voltage flicker protection – with discharge or flashover protection function. When there is high voltage discharge flicker during testing or boosting, the entire device will be automatically cut off without causing harm to the testing equipment and personnel. The electronic components inside the variable frequency power supply will not be damaged or broken down.
(5) Comprehensive protection – protection when the test line is connected incorrectly or disconnected. (such as measurement lines for variable frequency power supply main controller, excitation transformer, reactor, voltage divider, etc.).
(6) High voltage limit protection – When the output voltage of the equipment reaches 1.1 times the set voltage value, the system automatically locks to avoid the impact of overvoltage on the test sample caused by misoperation.
(7) Overheating protection – protection for power devices when the temperature is ≥ 80 ℃
(8) Emergency braking protection can be cut off urgently by clicking the emergency stop button on the display screen
