The PDS Series are CE-certified Regulated DC Power Supply units which comply with Power Supply Harmonics Current Regulations IEC1000-3-2, and a power factor of 95% (typical) is cleared. These models feature high reliability and various types of protection, and can be used as a power supply for reliability tests, endurance tests, aging and other electronics parts tests. By employing a unique switching and dropper circuit systems, the output noise is maintained at a minimized level.The input AC voltage is possible from 90 to 246 volts without any modification. Furthermore, these models are designed in a smaller size and a lighter weight compared to conventional models.
