Profile:
The ultra-low frequency with rated voltage less than or equal to 50kV adopts a single link structure (a booster); The ultra-low frequency of more than 50kV adopts a series structure (two boosters in series), which greatly reduces the overall weight and enhances the load capacity, and the two boosters can be used separately for the ultra-low frequency of low voltage levels.
Current, voltage, waveform data are directly sampled from the high voltage side, so the data is accurate.
With overvoltage protection function, when the output exceeds the set voltage limit value, the instrument will stop protection, the operation time is less than 20ms.
Overcurrent protection function: designed for double protection of high and low pressure, the high pressure side can be stopped according to the set value; When the current on the low voltage side exceeds the rated current, the shutdown protection will be carried out, and the operation time is less than 20ms.
The high voltage output protection resistor is designed in the booster body, so there is no need to connect another protection resistor outside.
Because of the high and low voltage closed loop negative feedback control circuit, the output has no capacity rise effect.
Features:
At present, mechanical methods are used at home and abroad for modulation and demodulation to produce ultra-low frequency signals, so there is a sine wave waveform is not standard, the measurement error is large, the high voltage part has spark discharge, the equipment is bulky, and the two and four quadrics of the sine wave also need high-power high-voltage resistance for discharge and shape, so the overall power consumption of the equipment is large. This product can overcome some of these shortcomings.
