Fullerton, Calif. TT electronics' BI Technologies Electronic Components Division offers a power factor correction (PFC) evaluation board for circuit testing. The ready-to-run evaluation board contains all of the required control and power circuitry, together with the required inductor assembled onto a compact board, to test PFC modules.
The PFC evaluation board allows designers to test circuits to ensure that the module will operate at a specified tolerance, said the company. The evaluation board features correction to near unity power factor and better than 95% efficiency, enabling it to accurately evaluate a variety of applications, including switching power supplies from 500 W to 3000 W, motor drives, servo amplifiers, solenoid drivers, solid-state relays and three-phase rectifier bridges.
The evaluation board accepts 85 to 265 Vrms input voltages at 50 Hz to 60 Hz, and is capable of handling up to 3 kW of power with a heat sink.
PFC modules are available in three standard configurations. Designated the 7720 series, the modules suit power supplies ranging from 500 W to 3000 W, and are capable of replacing up to ten TO-220 or TO-247 discrete power semiconductors required to achieve power factor correction in a conventional power supply design, according to the company.
Pricing: The PFC evaluation board is priced at $199.
Delivery: Delivery is from stock to 12 weeks.
