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