SVC Inductive Load Drivers Selection Guide: Technical Criteria & Application Standards
SVC Inductive Load Drivers selection guide: technical parameters, mounting and compliance standards, and Tibcon, Entes, Tense comparison.
An SVC inductive load driver is an electronic driver module that, on a command from the power factor correction relay, switches single-phase shunt reactors in steplessly from zero to full power. It is used in facilities where reactive power changes quickly or is unevenly distributed across the phases, to eliminate separately in each phase the capacitive excess that contactor-switched steps cannot balance. The Entes SR and Tense SRL series include models with driving ratings of 5 kVAr, 10 kVAr, 20 kVAr and 30 kVAr, while on the Tibcon side there are modules defined by per-phase power such as 3x3.33 kVAr, 3x10 kVAr and 3x20 kVAr. Choose the driver by the per-phase power of the shunt reactors to be connected, its compatibility with your relay, the maximum permitted fuse current and the recommended cable cross-section. Product data specifies a separate thermal input for each reactor, a test button and status LEDs, and on some models a cooling fan. Despite the word driver in its name, the SVC inductive load driver is not a motor speed drive; it does not provide correction on its own without the shunt reactors and the relay. The SVC Inductive Load Drivers category on Welibaba includes 14 active models from leading manufacturers such as Tibcon, Entes, Tense.
Key Technical Parameters for Selecting SVC Inductive Load Drivers
To specify the right SVC Inductive Load Drivers model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Maximum Connectable Shunt Reactor | 3, 3 × TNS-1, 66 (230V), 3 × TNS-10S (230V) | Verify against project schedule and load calculation |
| Power | 3x1, 66 kVAr, 3x10 kVAr, 3x16 | Verify against project schedule and load calculation |
| Supply Voltage | 210-250 VAC (L-N) | Verify against project schedule and load calculation |
| Connection Type | Yıldız | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in SVC Solutions.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as SVC Shunt Reactors.
