Additional Details

The SP1650 series is available in various models with different input voltage ranges, output voltages, and output power ratings. The isolation voltage typically ranges from 1 kVDC to several kVDC, depending on the specific model. The operating temperature range is typically specified for industrial environments. These converters are commonly used in applications where isolation is required for safety or to prevent noise from affecting sensitive circuits. The compact size of the SP1650 series makes it suitable for densely populated circuit boards. They are also used in applications where compliance with safety standards (e.g., IEC 60950, UL 60950) is required.
