Lowering the Cost of Solar PV Inverters, Devices Feature Rated Voltage to 570 V at +60 °C, Category Voltage of 475 V at +105 °C, and Open-Circuit Voltage Up to 600 V
Malvern, PA (GLOBE NEWSWIRE) - Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has upgraded the Vishay BCcomponents 193 PUR-SI Solar series of snap-in power aluminum capacitors with a higher rated voltage of 570 V and a category voltage of 475 V. Targeted at solar applications, the devices offer operation up to 600 V at specific conditions, long useful life, and high rated ripple current up to 2.46 A at +105 °C and 100 Hz.
At 570 V, enhanced 193 PUR-SI Solar series devices feature a maximum operating temperature to +60 °C and endurance of 5000 hours (no ripple current applied). At 475 V, the maximum temperature can be extended to +105 °C, and the useful life is 6000 hours. With their ability to fulfill the open-circuit voltage condition up to 600 V, the components lower the overall cost of solar PV inverters by reducing the number of electrolytic capacitors required, allowing designers to use one capacitor for string input voltages of 600 V and two for 1200 V.
Featuring a cylindrical aluminum case with a pressure relief valve, insulated with a blue sleeve, 193 PUR-SI Solar series capacitors are available in five case sizes ranging from 35 mm by 30 mm to 35 mm by 60 mm. As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the RoHS-compliant devices are ideally suited for DC-Link buffering and filtering applications. In addition to solar PV inverters, typical end products will include industrial motor controls and power supplies.
