Active Harmonic Filter (AHF)
- Reduces THD within IEEE – 519 limits
- Dynamic correction of THD
- Improves both distortion & displacement Power Factor
- 3 Phase 3 Wire AHF to be used where 3rd Harmonic Mitigation is not required
- 3 Phase 4 Wire AHF to be used where 3rd Harmonic Mitigation is required
- Modular Design allowing for future expansion
- Ease of Monitoring using Touch Screen HMI
- Flexibility of Configuration in both open loop (load side sensing) & closed loop (source side sensing)
* Standard CAT. No. Configuration

Type tested APFC Panels – Safe, Reliable and Smart solution to maintain Power Factor
Type tested and certified design
- Engineered to the highest standards – Type tested as per IEC 61439-1&2, IEC61921 & IS13947
- Ingress Protection up to IP42 as per IEC 60529, IS2147 to protect equipment under harsh environments
Reliable
- Worry free PF management with 4 quadrant PF controller
- Certified for better thermal management as per IEC 61921
- Design verified assemblies of both constructional & permanence
Requirements
Separate section for detuned reactors, capacitors & switchgear ensures longer life of components & less worry on maintenance
Safety
- Form 3B separation (compartmentalized design for switchgear)
- Bus bars with more clearance than prescribed in standards
- A minimum of IP2X degree of protection even when the doors / covers in open condition
- Earthing of each and every door and structural members
Zero stray voltage on doors & covers ensures both operator & equipment safety
