The modules are programed from to % of rated output via a to + volt DAC compatible high impedance programming input voltage. The CB Series features current and voltage monitoring, built-in protection against programming overvoltage, and thermal shutdown. Temperature drift is typically less than PPM/ C. A built-in reference voltage source can be used in lieu of the programming voltage. The CB Series 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. An externally accessible potentiometer provides adjustable gain trim, allowing for individual calibration of units. A proprietary encapsulation process and high performance formula are used to achieve excellent high voltage and thermal properties. Positive and negative outputs are offered. 9J PAGE

At Maximum Rated Output Voltage.. Specifications after hour warm-up, full load, at C unless other wise indicated.. Typical Performance.. All grounds internally connected, except case. There should not be more than volts potential between the case ground (pin ) and the circuit ground (pins and ). Isolated case assists low noise design efforts. Case pin must be connected to ground for proper operation.. Proper thermal management techniques are required to maintain safe case temperature at maximum power output.. %.. SET POINT ACCURACY refers to the ability of the unit to accurately deliver the voltage intended by the applied programming. The resultant output voltage will be within +/-% of that programmed. LINEARITY refers to how much the transfer function can deviate from a straight line in the absence of any set point error. GAIN ADJUSTMENT refers to the ability to alter the gain of the circuit to bring the resultant output voltage to the programmed setpoint. This is intended to allow compensation for set point accuracy error. XP-EMCO reserves the right to make changes on products and literature, including specifications, without notice.
