Product Features

★Current, voltage, and waveform data are directly obtained through high-voltage side sampling, so the data is true and accurate
★Overvoltage protection: When the output exceeds the set voltage limit, the instrument will shut down for protection, with an action time of less than 20 milliseconds
★Overcurrent protection: designed as a dual protection of high and low voltage, the high voltage side can be precisely shut down for protection according to the set value; When the current on the low-voltage side exceeds the rated current, shutdown protection will be implemented
★The high-voltage output protection resistor is designed inside the boost, so there is no need to connect another protection resistor externally
★For products with a voltage of over 50kv, the series combination method can achieve multiple uses for one machine, making it extremely convenient to use
★Due to the use of high and low voltage closed-loop negative feedback control circuit, there is no capacitance rise effect in the output
★Measurement accuracy: 2%                                   
★Voltage positive and negative peak error: ≤ 3%
★Voltage waveform distortion: ≤ 5%                      
★Output frequency: 0.1Hz, 0.05Hz, 0.02Hz
★Power supply: AC 50Hz, 220V ± 5% (generator: AC 50Hz, 220V ± 5%)
★Test time: Handover: 60 minutes     
★Prevention: 5 minutes (can run for a long time)
