Product Description:
Manufactured to improve the performance of variable frequency drives (VFDs) by means of input impedance, the KEB top-rated DR Motor Input Chokes series has component number 07.DR.B08-4951. This impedance extends VFD component lifetime and helps to lower harmonic distortion. Rating for a voltage of 400 V, the choke runs within a frequency range of 45 to 65 Hz. Its weight is 1.6 kg and its measurements are 96 x 72 x 115 mm.
Designed for 3-phase systems, the gadget can manage up to 6 A in current. The product's claimed 4.88 mH inductance helps to explain its efficiency in filtering and lowering of electrical noise. Its 22 W power loss should be taken into account when designing systems with regard to energy economy. Built to resist a maximum temperature of +90°C, the choke guarantees dependable performance under a range of environmental factors. Its IP20 rating indicates protection against solid items bigger than 12.5 mm but no particular protection against liquids. T45/B is the insulation class; it indicates thermal durability and fit for particular uses.
The part number 07.DR.B08-4951 uses screws 4.8 x 9 mm and has a 56 x 47 mm fixing size for installation. The conductor's 2.5 mm² cross-section fits accepted guidelines for devices of this kind in terms of normal wiring. The +40°C is the recommended ambient temperature for best functioning, therefore guaranteeing that the choke runs effectively in normal industrial surroundings. These characteristics make the DR Motor Input Chokes 07.DR.B08-4951 model a dependable part for improving VFD lifetime and performance.
