Beschreibung
|
The size is determined by the energy E = 0,5 x L x I2. All given values are calculated for low warming and low humming. With forced cooling, smaller dimensions are possible. If there is only a bit of over temperature allowed, the dimensions will increase.
Reactors for one-phase loads and electronic devices with the following advantages:
Use as an armature circuit reactor:
- reduction of harmonics in the motor and thus an increasement of the motor efficiency at
one-phase applications
- reduction of current noises in the motor
- increasement of the total inductance of the motor circuit for DC motors with low inductance
Use as an intermediate circuit choke or boost converter with harmonics
Harmonics with high current-stress can be absorbed very well, because of the low-loss cut cores

Frequency range: 50 Hz up to 20 kHz
Test voltage: winding - core: 2,5 kV
Good EMC ratio
High thermal stability
Temperatureclass: B or F
Ambient temperature: 40°C
Fire class UL94V0
Prepared for protection index I
Protective class: IP00
Voltage range: 0 - 400 V, other values on request

The given value of energy is only a guideline
Current: Can be defined by customer, inductance is the result of type size and energy
Inductance: Can be defined by customer, current is the result of type size and energy
Tolerance of energy +/- 30%
Block terminals are shock proof conform to VBG4,
Flat connectors for bolts or plugs are not shock proof
To reduce losses and dimensions, it is possible to use amorphous or nanocrystalline core materials
