Electrical Characteristics & Description
FCCT Series units are extremely versatile, allowing the user to float the high voltage up to 5 kVDC above the input line. These power supplies are ideal for Electrostatic chuck, CRT, and other electro-optical applications. Each unit is encapsulated in an anodized aluminum case which provides electrostatic shielding and heat removal. The calculated MTBF is 70,000 hours at 71 deg C case temperature.
The FCCT Series high voltage power supplies are regulated by virtue of Pulse Width Modulation topology. The input voltage is stepped up by resonant action to a high voltage output which is floating with respect to the input ground. The output voltage is sensed using a unique patented circuit to allow fully floating operation with no Galvanic connection to the input power side of the power supply.
The output voltage adjustment is via a 10 turn potentiometer located on the top surface of the unit. The output voltage may then be controlled in either of two ways. In voltage programming mode, a control voltage between 0 VDC and 5 VDC will adjust the output between 0% and full output. In the resistance programming mode, a resistor placed between Pin 2 (5.0-V reference output) and Pin 3 (V control) will set the output to a voltage which depends on the value of the resistance used. Typically a 5 kOhm resistor will set the output voltage to 50%. Zero resistance yields full output. The maximum output current is limited to approximately a 120% above the nominal value as determined by the maximum output power for the supply. The current limit circuitry internal to the FC high voltage power supply has a reaction time constant of less than 0.01 second.
The center tapped version of the FCCT series generates a + and – output for example the FCCT-6 will provide +/- 300V output.
