STEVAL-IHT003V2

Оценочная плата, E-Starter с низким уровнем потерь, для схемы стартера компрессора на базе ACST6.

The STEVAL-IHT003V2 from STMicroelectronics is a low loss e-starter evaluation board for compressor starter circuits based on the ACST6. The STEVAL-IHT003V2 evaluation board represents an innovative solution patented by STMicroelectronics to reduce the power losses caused by positive temperature coefficient (PTC) resistors in compressor starter circuits. The solution features an ACST6 AC switch device to turn off the PTC current after motor start-up. The design reduces starter standby losses from 2.5W to 380mW for 230V applications, or 2.5W to 40mW for 100V applications. Before using the board with a compressor, the PTC behaviour must be checked (especially VPTC1 and VPTC2 levels) and different R4 resistor values may be required.

• Suitable for refrigerator and freezer compressor applications
• Reduces PTC resistor power losses
