AC Series
Electrical Characteristics & Description
The AC Series power supplies are a line of compact high voltage DC to AC inverters. The model number describes the output in volts peak to peak. The two output terminals are floating from the input. The maximum isolation voltage from output to input is 3 kVDC. All power supplies offer reverse voltage and short circuit protection.
The AC power supply produces a quasi - sinewave output. To determine the RMS value, the RMS output voltage is found by dividing the peak to peak voltage by 2.5. (An ideal sine wave factor is 2.82 . A true squarewave is 2.00).
The output voltage of the AC power supply is directly proportional to the input voltage. The power supply will start with input voltage as low as 2 volts, and will not be damaged by inputs as high as 18 VDC. The output frequency of operation is typically between 20 to 50 kHz, depending on output impedance. This makes the AC supply ideal for corona generation or ionization.
The AC Series high voltage power supplies are driven by an input voltage placed onto the input pins, of any voltage between 0 to 12 VDC. There is NO internal connection between the input and output pins. As can be seen from the above, the output voltage is nearly linear with respect to input except near the lower input voltage region. Here, the output drops off rapidly as the input is lowered with the minimum input voltage needed for reliable starting being approximately 1.0 VDC.
The maximum output current ability is achieved at full output voltage and must be derated linearly as the input voltage decreases. Therefore, a 1 kVpp 5-watt unit, which is capable of providing 12.5 mA at 1 kVpp will only be able to provide 6.25 mA at 500 volts peak-peak out indicating that the output power capability is parabolic with respect to output voltage.
AC power supplies may be driven from a three terminal regulator, or run closed loop with a suitable regulation scheme. The input capacitance is 10 uF AC bypass. Vout max is defined as the maximum output voltage in peak to peak voltage of the power supply with the standard 12-V input. Each unit is encapsulated in a high thermal conductivity epoxy resin which eliminates problems associated with moisture.
