Compensation Solution (RPCF-12S for example)
| Compensation solution | Application | Switching method |
| 12-0 (three-phase compensation for all) | Power of three phases isbasically balanced | According to total three-phase reactive power |
| 9-1 (three-phase compensation for 9 circuitsand single-phase compensation for 1 circuit) | Little power differenceamong three phases | It switches to three-phase compensationcapacitor according to the group with thesmallest single-phase reactive power, andswitches to single-phase compensationcapacitor in case of inadequate orimbalanced reactive power |
| 6-2 (three-phase compensation for 6 circuits, and single-phase compensation for 1 circuit) |
||
| 3-3 (three-phase compensation for 9 circuitsand single-phase compensation for 3 circuits | ||
| 0-4 (splitting, four paths per phase) | Serious power imbalance among three phases | According to single-phase reactive power |
The relationship between compensation scheme, number of output channels and output terminals
The LGRPCF3-12S controller has 12 outputs, numbered 1, 2, 3...12; the RPCF3-16 controller has 16 outputs, numbered 1, 2, 3...16. Under different compensation schemes and different output circuits, the RPCF3 will allocate the output control terminals in the following order: Phase A compensates for the first circuit, second circuit...; Phase B compensates for the first circuit, second circuit...; Phase C compensates for the first circuit, second circuit...; and the entire first circuit, second circuit... If the total number of channels set by the user is less than the maximum number of circuits supported by the hardware, the remaining terminals will be at the end (for reference, using the RPCF3-12S as an example, A: Phase A; B: Phase B; C: Phase C; G: ...).

2. High power factor measurement accuracy and wide display range.
3. Real-time display of total power factor (PF) and fundamental power factor (DPF).
4. Real-time display of three-phase voltage, current, active power, reactive power, and apparent power.
5. There are 12 encoding output methods for users to choose from.
6. There are up to 6 compensation options for users to choose from (shared compensation and distributed compensation based on the number of routes).
7. Up to 16 outputs.
8. User-friendly interface and easy operation
9. Various control parameters are digitally adjustable, intuitive, and easy to use.
10. It has two modes: automatic operation and manual operation.
11. Features overvoltage and undervoltage protection.
12. It has a power-off protection function so that data is not lost.
13. Current signal input impedance ≤0.01Ω
14. The target power factor has a wide adjustment range, from lagging to leading by 0.70.
