Features
RoHS lead-free-solder and lead-solder-exempted
products are available
Input voltage up to 144 VDC
Description
Single output of 3.3 to 48 VDC
The PSC and PSL Series positive switching regulators are No input-to-output isolation
designed as power supplies for electronic systems, where no
High efficiency up to 97%
input-to-output isolation is required. Their major advantages
Extremely wide input voltage range
include a high level of efficiency, high reliability, low output
Low input-to-output differential voltage
ripple, and excellent dynamic response. Models with input
voltages up to 144 V are specially designed for secondary Very good dynamic properties
switched and battery-driven mobile applications. The
Input undervoltage lockout
converters are suitable for railway applications according to
Output voltage adjustment and inhibit function
EN 50155 and EN 50121.
Continuously no-load and short-circuit proof
Two type of housings are available allowing operation up to
All boards are coated with a protective lacquer
71 C. The PSC Series is designed for wall or chassis
mounting with faston connections, whereas the PSL Series is
Safety-compliant to IEC/EN 60950-1 and UL/CSA
designed for insertion into a 19" DIN-rack and exhibits a H11

connector.
Various options are available to adapt the converters to
different applications.
