Application notes
General Use
- For models 6 kV or less, the case (blue lead wire), input (black lead wire), and output are not connected internally. For safety reasons, always connect the case, input, and output to the ground.
- For models 10 kV or more, the case (no lead wire) and input (black lead wire) are internally connected. For safety reasons, always connect the input to the ground. The * part in the figure below is not present on models of 10 kV or more.
- If the output is used as floating, refer to Floating Use with High-voltage.
- U3: up to 15 V
- U6, U10: up to 24 V
- Make sure that the wiring is properly connected to the product as shown in the figure above before operating the product.
- Apply the specified input voltage and set the voltage.
- Models of U3, 6 kV or less, do not have a discharge resistor built into the output. When using such a model with capacitive loads, etc., install a discharge resistor in the output.
- When quitting the operation of the product, turn off the input power.
Monitoring Output Voltage/Current
- C = 0.1 to 1 µF pass capacitor
- Instead of using a voltmeter or ammeter, inserting a resistor as shown in the figure and measuring the voltage at both ends of the resistor with a DVM.
Parallel Operation to Increase Output Current
- Valid only for the same model
- Do not parallel different models.
Reducing Output Ripple
- L = 1 m to 5 mH: A resistor is also available.
- C = 0.01 µF to 0.1 µF: Pay attention to withstand voltage.
Suppressing Input Ripple to Reduce effect to Input Power Source
- Ground at one point.
- L = 100 µH or more
- C = 100 µF/35 V or more
Generating Required Input Voltage for Output Voltage
When load regulation is large.
This circuit can also reduce the noise generated on the input power source.
When load regulation is small.
Install a capacitor with approx. 0.01 µF to 0.1 µF on the output side to reduce the ripple on the output voltage.
Pay attention to withstand voltage.
Floating Use with High-voltage
- Models of 6 kV or less are input/output isolated, therefore they can be used with the output floating.
- For models of 6 kV or less, the case (blue lead wire), input (black lead wire), and output are not connected internally.
- For safety reasons, always connect the case and input to the ground.
- U3: up to 15 V
- U6, U10: up to 24 V
The Ef + Eout is less than or equal to the value of "I/O Isolation" shown on the Models.
- Make sure that the wiring is properly connected to the product as shown in the figure above before operating the product.
- Apply the specified input voltage and set the voltage.
- When floating the output, lower the Ef impedance because the common-mode noise may occur.
- When quitting the operation of the product, turn off the input power.
NOTE
- This product is an embedded power supply, which has been designed and produced with full consideration for high-voltage safety. For further safety, ground it according to General Use and Floating Use with High-voltage.
- Avoid short-circuiting the load for long periods of time.
- Do not touch the output just after turning the product off, because high voltage may still present at the output. If you need to touch it, check with a voltmeter or similar device that the output voltage has dropped sufficiently, or wait until at least 20 minutes have passed. If the load is an open or capacitive load, the output voltage may not drop for a long time, so if you must touch it, be sure to discharge the output.
