Matsusada Precision is a leading company in high-voltage power supply. As a comprehensive power supply manufacturer, products of Matsusada Precision have advantages in size, performance, and reliability.
Suitable for precise control of magnetization and demagnetization by electromagnet!
DOM series is a four-quadrant bi-polar power supply which succeeded in miniaturization by high-efficiency switching amplifier method and electric power regenerative function.
It can also realize smooth demagnetization, thanks to large current which is required in magnetization of the electromagnet and four-quadrant operation that can perform both “source” and “sink” of electric power. By the simple operation on the front panel, the setting of output voltage/current and the outputting safely are available.
Isolated control is realized via optical communication. It is possible to prevent malfunction such as transient phenomenon by surge, lightning induction and exogenous noise.
[Controllable items] Output ON/OFF, setting the value of output voltage/current, switching CV mode and CC mode (A converter is required separately. Please ask our sales representative.)
Select the -LGob option when using power supply following environmental condition.
Factories which has a lot of noise (Ex.) in case of using power supplies and loads near motors and coils.
In case using power supply with high voltage floating (more than 250V)
The length between power supply and controller unit (PC or PLC) is more than 2-meter
When a capacitive load is more than 100pF (including a stray capacitance of output wire), the resonance in the output may occur. In that case, install 100-ohm (@0.1μF) to 1000-ohm (@1000pF) of high voltage resistance in the output in series. Please note that the frequency band will be limited as the formula written in the right figure when an amplifier is used with a capacitive load. In addition, when an amplifier is used for the use such as a corona discharge, the current which is higher than rating will flow and it will affect the amplifier badly. In this case, as well as the time to use an amplifier with a capacitive load, please install the output resistance and limit the current.
*Please avoid continuous inputting of high frequency which reduces output frequency of an amplifier.
An amplifier will be broken because of increase of internal loss.
