Characteristics
| Switching operation is silent, with no arc or transient inrush voltage and current. |
| Independent three-phase thyristor power chips reduce heat accumulation, enhance cooling, extend service life, and prevent malfunction due to interference. |
| Independent three-phase frequency detection (Detect Frequency) enables zero-phase switching (switching at zero voltage and zero current of the sine wave), eliminating inrush current during capacitor switching, protecting the capacitors and related electrical equipment, and reducing interference to other devices on the same line. |
| In case of unbalanced three-phase load, reactive power can be individually compensated according to each phase’s requirement. |
| High-speed switching and quick response provide reactive power compensation for briefly changing or transient loads. |
| Independent three-phase semiconductor equipment is protected by aR high-breaking fuses; abnormal load circuit interruptions trigger warning signals and output contacts. Phase loss abnormality protection also provides warning signals and output contacts. |
| Temperature-controlled cooling fan: fan activates at 55°C and stops at 45°C; includes over-temperature protection device with abnormal output contact control. |
| Optional built-in electronic capacitor discharge resistor (customizable). |
