Passive Filtering Module

RH-MPF Passive Filter Module Application : Used in passive filter devices to filter or suppress harmonics in the network, compensate inductive reactive power, and improve power factor. Characteristics : 1.Adoption of high quality switching elements as well as our own filter capacitor (RHAK) and reactor (RHLC); high reliability and long service life; 2.Filter design is simplified because its unnecessary for customers to do complex calculation and component selection; 3.All modules have been tuned exactly in factory inspection, so that the tuning accuracy and filter effect is guaranteed. It avoids unfavorable filter effect caused by component parameter deviation. 4.Easy installation. Technical Specification : 1.Rated voltage: 230V 400V, 660V,690V 2.Rated capacity: 10 60 KVar 3.Filtered harmonic times: 3th, 5th, 7th, 11th, 13th 4.Tuning accuracy: ±3% 5.Rated harmonic current: 20% 200% 6.Rated current: 10 200A 7.Loss: ≤ 6W/KVar 8.Insulation against ground: 3000V/min 9. Max. permissible voltage:1.1Un ( Un is rated voltage) 10.Max. permissible current: 1.3In ( In is rated current) 11.Discharging performance: discharging to 75V or less in 3 min after the power is disconnected (1 min when specially requested ). 12.Operation environment: indoor, altitude≤2000m, ambient temperature: -25 +50oC, Relative humidity ≤90%. 13. CE Certificate Note: 1.The harmonic current passed passive filter module should not be higher than its rated harmonic current, or the module may be out of operation or its service life may be shortened. 2. When harmonics of different times coexist, passive filter module for lower harmonics should be switched on first while passive filter module for higher harmonics should be switched off first. If they are switched in converse order, amplification of lower harmonics, invalidity and service life shortening of the module may be caused. 3. Different switches should work with different controllers. Customers can consult the controller manufacturer to get more details. 4.The module should be installed far from heat source in a cool and ventilative position. Suggestion : Compulsive heat dissipating device can be added to the module to prolong its service life.
