This quality is perfect also for use in the High Voltage Power Supply. It reduces pulsations is similar 120-150uF old oil capacitor! It is enough for use with anode current up to 2,0 amperes in one phase (witch 4,5kV to 9kW) or up to 10,0 amperes in 3 phase (with 4,5 kV to 45 kW) anode Power Supply. The best choice for pulsing loadings (CW and SSB big power high-linear amplifiers). These capacitors have no throws voltage and supplies of any front impulse of a anode current.
Peak Working Voltage: 7500 VDC
MAX. WORKING Voltage: 5000 VDC
Discharge current amplitude:up to 1400 Ampers !
Dissipation factor at f=50Hz: <0,008 !
Vibration 1-2000Hz witch acceleration: up to 10 G
Nonsingle shocks witch acceleration: up to 40 G
Single shocks witch acceleration: up to 500 G !
Material of electrodes:Composite of metals witch a special film coats
We have made HI-POT test for two 40uF/5kV capacitors:
We charged the capacitors up to 5000V with 50uA current, no problems and we got 8.6uA and 11,2uA leak current at 5000V. Next step was to charge it to 6000V, with 50uA current, no problems and we got 10.5uA and 13,1uA leak current at 6000V.
Absolutely safe for 6000VDc constantly without any limited!
We increased the voltage to 7000V and got 29uA and 33uA leak current. Next step was to charge it to 7500V, with 60uA current, at 7500VDc the self-discharge is still very small (46uA -> 0.05mA and 39uA->0.04mA) but we not recommend more 6500VDc for long term use.
