Product Description:
The 3EF-08 from Kollmorgen provides a durable Mains EMI Filter to control system stability and electrical safety in many industrial spaces.
This filter works well with power sources ranging from 3 x 60-172 V AC at both 50 and 60 Hertz frequencies with up to 10% variation in voltage. The product runs at a 240 V DC power level to meet demanding operational requirements. The 3EF-08 delivers various output current options at 7.5 A to 50 A meaning this driver can operate effectively in multiple motor configurations and power plans. The supplied AC fusing maintains 3 x 20 AM overcurrent protection strength that safeguards electrical systems better and lengthens their operational life. This EMI filter features both a ballast circuit that activates at 300 V and turns off at 285 V plus a 5.4 kW pulse power ballast. The system provides two ±15 V auxiliary outputs to support multiple secondary circuit tasks and offers extensive usability. Its small size of 1.4 kg and measurements of 220 x 233.4 x 45 mm make the 3EF-08 easy to adapt to existing arrangements without major changes. Under rated usage between 0 and 45 °C this product functions reliably while its power drops at temperatures above 55 °C.
The IP 00 rating shows its open frame design which needs installation in controlled settings because touch exposure lowers protection. Advanced control operations become possible through the 1 kHz bandwidth current loop and the 8.5 kHz dual output stage clock frequencies. At 12 W of quiescent dissipation, this device maintains minimal power wastage when it stays idle but remains powered. The Mains EMI Filter serves as an important device to ensure proper performance and meet all present-day industrial standards. It can be purchased at Wake Industrial with a one-year warranty.
