PKE532x series has an 18-75Vdc (100V peak) input range suitable for 24, 28 or 48 V nominals
PKE332x series input range is 9-36Vdc (50V peak)
Both parts are available with either ±12V or ±15V regulated dual outputs, and are 25.4 x 25.4 x 6.4mm (1x1x0.4in). Efficiency is typically in the high 80s percent.
“They are a great fit for high reliability applications where cost is important, such as industrial and communication electronics, instrumentation devices and mobile and battery-operated systems,” according to the company. “A particular advantage of these new variants in the PKE series is their ability to operate to over 100°C ambient with airflow and derating.”
Encapsulation protects the converters in high shock and vibration environments, or where dust and humidity are present. Five-sided shielding is provided by the metal case.
Input-output isolation is 1.5kVdc, meeting ‘basic’ insulation and safety requirements according to IEC/UL 62368-1.
EN 55032, CISPR 32 and FCC part 15J EMC conducted emissions standards can be met with an external filter, specified in the data sheets.
Remote on/off control is provided, and both series include protection against over-temperature, input under-voltage, output over-voltage, over-current and short circuits.
