  • Product introduction




    The electrostatic electret high-voltage power supply for melt blown cloth mainly has the following two functions in the production process of melt blown cloth with 99 filtering performance:

    1. Inject static charge into the electrostatic electret master batch of the melt blown cloth.

    2. Make the static charge stable and long-term latch in the melt blown cloth.

    The 99-level filtration performance meltblown electrostatic electret high voltage power supply needs to meet the following technical parameters:


    Input: AC220±10%, maximum current 15A.

    Output: 60KV and other maximum voltage output is optional, 0V to full adjustable.

    Output power: 2000W

    Voltage control: The multi-turn potentiometer on the power supply panel can set the output voltage from 0V to full.

    Current control: The multi-turn potentiometer on the power panel can set the current from 0 to full.

    Voltage regulation :

    Relative load: 0.005%+500mV (no load to rated load)

    Relative input: ±0.005%+500mV (input voltage change is ±10%)

    Current regulation:

    Relative load: 0.01%±100uA (no load to rated load)

    Relative input: ±0.005% (input voltage change ±10%).

    Ripple voltage: 0.03% P-P (the main technical indicator for stable injection of electric charge and no disturbance. Charge disturbance is likely to cause the charge to overflow the electret masterbatch)

    Temperature coefficient: ≤25ppm/℃, higher temperature coefficient can be customized.

    Stability: less than 100ppm every 8 hours after starting on for half an hour. (Key technical requirements for stable latching.)

    Ambient temperature: 0 to +50°C.

    Storage temperature: -40℃ to +85℃.

    Voltage and current indication: 4-digit digital panel meter with an accuracy of 1% under rated output conditions.


    1200W:60KV height 88mm (2U) width 483mm, length 610mm,
