CB101N

DC-HVDC CONVERTER 

## CB Series 

## 1W **CONVECTION COOLED** 

The CB Series is line of miniature, well-regulated high voltage power supplies providing clean and reliable high voltage in a shielded, PCB mount package. They are programmed from 0 to 100% via a 0 to +5 volt DAC compatible high impedance programming input voltage. A built-in reference voltage source can be used in lieu of the programming voltage. 

Current and voltage monitoring outputs are standard on all models. Safety features include built-in protection against programming overvoltage and thermal shutdown. Temperature drift is less than 50ppm/°C. The units exhibits very low ripple, noise, and EMI/RFI by utilizing a quasi-sinewave oscillator, shielded transformer, excellent filtering techniques, and an isolated steel enclosure featuring a separate grounding pin. A proprietary encapsulation process and high performance formula are used to achieve excellent high voltage and thermal properties. These component level power supplies are ideal for easy integration i ~~n~~ to compact, sensitive equipment.

Notes: 

1. Maximum rated output current is available at maximum rated output voltage. 

2. Specifications after 1 hour warm-up, full load, 25°C unless otherwise indicated. 3. Proper thermal management techniques are required to maintain safe case temperature. 

   5. GAIN ADJUST refers to the ability to alter the gain of the circuit to allow for setpoint accuracy error. 

   6. LINEARITY refers to how much the transfer function can deviate from a straight line in the absence of any set-point error. 

4. SET POINT ACCURACY refers to the ability of the unit to accurately deliver the programmed voltage.
