Switching Regulator

For those electronic systems requiring rugged, high efficiency, non-isolated power, Power-One offers a broad lineup of positive switching regulators with high reliability and excellent dynamic response.
PSS Series

PSS Series

The PSS/PSK Series from Power-One are DC-DC PSRs designed as power supplies for electronic systems where no input-to-output isolation is required, yet need high efficiency over the input voltages that range up to 144 VDC.

Power-One’s PSS/PSK series of positive switching regulators offer up to 97% efficiency across their 8 to 144 VDC input voltage range, with 3.3 to 48 VDC output capacity, as well as high reliability, low output ripple and excellent dynamic response.  Models with input voltages up to 144 V are specially designed for secondary switched and battery-driven mobile applications.
