Features
• Input voltage up to 144 VDC
• Single output of 3.3 to 48 VDC
• No input-to-output isolation
Description
• High efficiency up to 97%
The PSC and PSL Series positive switching regulators are
designed as power supplies for electronic systems, where no
input-to-output isolation is required. Their major advantages
include a high level of efficiency, 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. The
converters are suitable for railway applications according to
EN 50155 and EN 50121.
• Extremely wide input voltage range
• Low input-to-output differential voltage
• Very good dynamic properties
• Input undervoltage lockout
• Output voltage adjustment and inhibit function
• Continuously no-load and short-circuit proof
• All boards are coated with a protective lacquer
Two type of housings are available allowing operation up to
71 °C. The PSC Series is designed for wall or chassis
mounting with faston connections, whereas the PSL Series is
designed for insertion into a 19" DIN-rack and exhibits a H11
connector.
Safety-compliant to IEC/EN 60950-1 and UL/CSA
60950-1 2nd Ed.
Various options are available to adapt the converters to
different applications.
