9) Frequency adjusting range: 20Hz~300Hz
10) Frequency adjusting sensitivity: ≤0.1Hz, output frequency instability ≤0.05%
11) Insulation level: input, output terminal to ground ≥2kV/AC/1min
12) Cooling type: forced air cooling
13) Sound level ≤70dB
14) Temperature raise: bridge arm temperature raise <40K, electric circuit temperature <40K, main circuit hottest point <50K;
15) Working time: continuous working 90min under rated output capacitance;
16) Frequency adjust within setting range, voltage output stable.
17) Variable frequency power source and control cabinet, voltage divider and control cabinet are connected by optical cable, making sure no damage to control cabinet when test object breakdown.
18) Main body is separated from control, display, protection parts. Main body and protection are in one.
19) Display is in one (separate). Control and display are portable.
20) Variable frequency power source has the ability of anti anti-electromagnetic interference. Under high field interference, Its measuring accuracy and control protection can meet requirement. 
It equips with excellent magnetic shielding component. All lead wire are made of high permeability magnetic alloy, no space radiation.
