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 completely.

Key Lock Function

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.

Digital interface

Digital control of USB/RS-232C/RS485/GPIB and one-control on master slave operation.

Digital interface
(A) CO-M Cable
One 2 meter cable is provided per unit without interface options. Please notify your sales representative if you need a longer cable or additional cables.

Master/Slave control

The Master/Slave control function allows you to control up to 32 units connected in parallel from a single unit.

This is not a function for parallelly connected power supplies to give out average output current.
It has to hook with each same model in the same series in master-slave.

  • Master/Slave control is only possible with units with the same model number.
  • But, it is valid only power supply without -LGob, -LUs1, and -LEt option.

Options

-LGob: Optical Interface Board *1 *2

  • -LGob: Optical interface board + optical cable 2m
  • -LGob(Fc5): Optical interface board + optical cable 5 m
  • -LGob(Fc10): Optical interface board + optical cable 10 m
  • -LGob(Fc20): Optical interface board + optical cable 20 m
  • -LGob(Fc40): Optical interface board + optical cable 40 m

Optical communication offers insulation control. It is to prevent malfunction such as transient phenomenon by surge, lightning induction, and exogenous noise.

Select the -LGob option when using power supply following environmental condition
  • Factories which has a lot of noise
    (Example.)in case of using power supplies and load near motors and coils.
  • In case using power supply with high voltage floating (more than 250 V)
  • The length between power supply and controller unit (PC or PLC) is more than 2-meter
Optical Interface Board

-LUs1: USB Interface Board *1 *2

Enable digital control via USB

USB hub shall be required between VDD and PC when control multiple VDD.

USB Interface Board

-LEt: LAN Interface Board *1 *2

Enable digital control via LAN

Hub shall be required between VDD and PC when control multiple VDD.

LAN Interface Board

-L(Mc0.5), -L(Mc0.15) *2: Communication cable length change

Change length of CO-M cable to 0.5-meter and 0.15-meter long. (Only either can be selected.)

-L(400V): Input voltage 400 V

  1. If you select this option, standard digital interface and master-slave function will not be equipped. Also, please see the CO series datasheet for detail of function of digital interface function.
  2. These options cannot be selected together. Only one of each can be selected.

How to Order

When ordering, suffix the following option mark to the model number.
VDD6-133-L(Mc0.5)
VDD350-18-LGob(Fc20)
VDD650-7.6-LUs1(400V)
(alphabetical, input voltage order)

Operations

VDD series of same model number can be connected in series or parallel to increase output voltage or current. In that case, local control or the control in the digital master/slave is recommended.

Because the common of the outside input/output control connector (TB1) is connected to the negative output, please do not connect common more than two.

Series operation

Total output voltage is to be up to 250 V. Therefore for models with output voltage of over 250 V, series operation cannot be conducted. Output current is to be the smallest current of those.

Series operation

Parallel operation

Please keep all the settings of voltage the same. Output current will be the summation of each current. Please keep OVP level of power supply maximum to prevent any damage.

Parallel operation

Split operation

+output and -output are available.
