• Using the -I5 and -I10 Interface Options on UltraVolt High-Voltage Power Supplies
  are compensated for, providing a true output current monitor without any offsets. Pin 4 – Enable: Logic high between 2.5V and 15V will enable the power supply a logic low between 0V and 1V or an open circuit will disable the power supply. The input impedance is 1kΩ; a resistor to ground will disable...
• Interfacing with the E Series Precision HVPS
  resistor can be used to create a logic signal, or the pin can be used to ground an LED to provide an illuminated indicator showing the operating control mode. See Figure 2 for usage suggestions. Pin 6, 15 - Signal Ground: The signal ground and power ground are common inside the power supply...
• Application Note: Preventing Motor Drift After an E-stop Condition
  Recommendations: This problem occurs due to the DC Bus Capacitor within the drive or amplifier holding the bus voltage after power is no longer applied. It still could take several seconds for the Capacitor to dissipate it's voltage through the motor which causes the motor to turn. What you need...
• Parallel & Series Operation
  be bourne in mind that as the output power of the supply rises, the voltage drop and power dissipated rise. The power rating of the resistor. should be carefully calculated. At higher currents, the series resistance should be reduced to perhaps 25-30m. In critical applications where continuous operation...

• Current-Sense Transformer Application Design Guidelines
  such as switch-mode power supplies, current transformers are generally used for control, circuit-protection, and monitoring features. With the increasing availability of OTS (Off-The-Shelf) current transformers, a simple guideline can greatly help in the selection of proper and cost-effective components...
• How to Minimize Warm-Up Drift in Pressure Sensors
  and diaphragm surface cause an imbalance in the resistor bridge. The temperature rise of the resistor-sensing element is proportional to the dissipated power and therefore proportional to the square of the excitation voltage of the sensor (DTaV 2). Thus, reducing the excitation voltage by a factor...
