LVAC power capacitors improve connection with lever-operated terminal
Claimed to be the first LVAC power capacitors with a lever-operated spring terminal connection, the ESTAspring, the ESTA PhMKP series is available from Vishay Intertechnology.
The company claims that they reduce assembly time by 60 per cent and increase connection reliability in high vibration applications.
Most tubular power capacitors feature an IP20 terminal block with a screw connection, but the ESTAspring connection is screwless. This enables a faster and easier connection, and the continuous contact force ensures the highest level of contact reliability over the devices’ entire lifetime, says Vishay.
Without the need to tighten screws, the metallised polypropylene film capacitors provide a completely maintenance-free connection for low voltage power correction and harmonic filters in wind power plants, solar panels and inverters, and thermal power stations. A simple optical check ensures the connection is successful.
The PhMKP series offers voltages from 230 to 1000V, the output from two to 37.1kvar, and maximum terminal current of 90A. The capacitors are corrosion-proof, the spring is stainless-steel spring, and available in oil-filled and dry gas-filled versions. The devices are RoHS-compliant, halogen-free, UL- and cUL-approved.
Samples of the PhMKP series are available now. Production quantities are available with lead times of 10 weeks.
