Suitable for precise control of magnetization and demagnetization by electromagnet!
DOM series is a four-quadrant bipolar power supply that succeeded in miniaturization by a high-efficiency switching amplifier method and electric power regenerative function.
It can also realize smooth demagnetization, thanks to a high 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.
- Though the new model is the same 1 kW
- output class, height becomes half
Features and Benefits
- Source and sink of current of ±125 A maximum is available in spite of the compact size of height 3 U.
- DOM can control electromagnet quickly and precisely because of four-quadrant operation.
- Utilizing electricity effectively* and reducing the generation of heat are available because of electric power regenerative function.
- Low ripple, excellent stability and useful protection realize high performance and safer safety.
* It is designed on the assumption that all regenerated electrical power is consumed on the premises.
Applications
Control of electromagnet, testing for in-vehicle electrical components and various motors, evaluation test for solar panel and film formation (electroplating)
There is a dedicated power supply suitable for such use, so please feel free to refer.

Tech Notes
Capacitive Load
When a capacitive load is more than 100 pF (including a stray capacitance of output wire), the resonance in the output may occur. In that case, install 100-ohm (@0.1 μF) to 1000-ohm (@1000 pF) 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 signal which reduces output frequency of an amplifier. An amplifier will be broken because of increase of internal loss.
