VDD series

Programmable DC-DC converter with multi function and excellent operability

Programmable DC-DC converter with multi function and excellent operability

VDD series are high power and variable output DC-DC converters which can be operated on DC.
Because the DC operation, VDD is most suitable for many applications.
For example, it is the best choice for R&D of next-generation energy systems and anti-disaster measure systems, such as Smart house in which electricity is supplied as DC mutually between home rechargeable batteries and EVs, and Voltage adjustment when driving DC electronic equipment by emergency large rechargeable batteries.
Furthermore, you can istall VDD into your system easily, because it is equipped with various digital interface such as LAN (Ethernet*1) and USB. *2

*1 : Ethernet is a registered trademark of Xerox Corp.
*2 : Adaptors will be needed additionally. And, -LGob option will be needed if it will be used under specific condition. Please see page 10 for detail.

Standard functions

Key Lock Function

Lock all front panel operation to prevent erroneous operation. (emergency stop by power switch is still valid. )

Lock all the function other than reset lock mode. This mode is good for purpose to avoid mis-operation complelely.

Dual Tracking, Multiple Outputs

Dual tracking control, which enables both positive and negative outputs simultaneously in master slave operation, is possible.
Multi outputs and various versatile operations are also possible by combining above dual tracking control and slave local mode.
Positive and negative output(+V, -V) of dual tracking control and set output voltage of slave local mode can be output simultaneously by turning on the master unit.

Technical Notes

Connection · Operation

Connection of load

  • Please use a short lead wire that is sufficiently thick for the connection.
  • Please use PVC electric cable (105°C) that can fully tolerate the voltage used. It is necessary to consider current capacity, length limit of output wire by sensing (0.5V /lead) and so on for wiring with load. Please refer to the following diagram to determine the thickness of cable.

DC Power Supplies VDD Series connection of load 1

Parallel connection of load

DC Power Supplies VDD Series Parallel connection of load

Connection of load
Please insert a diode of which rating is bigger than output voltage and current of power supply to protect the power supply from kick back of load.

Definition of specifications

Specifications in this catalog, except otherwise specified, refer to values when maximum rating output (full scale*) after 2-hour warm up.

Applicable scope of specifications
"F.S × catalog value(*)" is applied for ripple, stability, regulations and temperature coefficient, and "value if F.S × ±1%(*)" is applied for high-voltage output linearity, monitor linearity and display linearity, both in the range of 10% to 100% of maximum rating output.

DC Power Supplies VDD Series Applicable scope

Ripple
Indication is in rms that includes high-frequency noise.

Preset
Preset value does not show the actual output status accurately. If you need an accurate setting, conduct actual output without load and set a voltage. Also for setting current, conduct output after shorting the output terminal and gradually raise current before setting at a desired value.
