PowerLogic™ PFC Capacitors
LV aluminium can capacitors
Overview
Features
VarPlus Can are low voltage aluminium can capacitors specially designed to contribute to power quality and power factor mitigation and deliver a long working life in industrial networks, with low losses in standard, heavy-duty and severe operating conditions.
- Technical data:
- High life expectancy up to 160,000 hours
- Voltage up to 830 V
- Power ratings up to 50 kvar
- Operating temperature up to 70 °C
- Degree of protection IP20
- Compliant with standards IEC 60831-1 and -2.
VarPlus Can capacitors must be selected depending on the working conditions expected during their lifetime. Since harmonics are caused by non-linear loads, an indicator for the magnitude of harmonics is the ratio NLL of the total power of non-linear loads to the power supply transformer rating.
| Solution: description | Recommended use for | Max. condition |
| SDuty: Standard capacitor | Networks with non significant non-linear loads | NLL = 10 % |
| > Standard over-current | 1.5 IN | |
| > Standard operating temperature | 55 °C (class D) | |
| > Normal switching frequency | 5,000 / year | |
| > Standard life expectancy | up to 100,000 h | |
| HDuty: Heavy-duty capapcitor | > Networks with a few non-linear loads | NLL = 20 % |
| > Significant over-current | 1.8 IN | |
| > Standard operating temperature | 55 °C (class D) | |
| > Significant switching frequency | 7,000 / year | |
| > Long life expectancy | up to 130,000 h | |
| Energy: Capacitor for special conditions | > Networks with significant number of non-linear loads | NLL = 25 % |
| > Severe over-current | 2.5 IN | |
| > Extreme operating temperature | 70 °C | |
| > High switching frequency | 10,000 / year | |
| > Extra long life expectancy | up to 160,000 h |
