DC/DC Converters TEM 2 Series, 2 Watt CB Scheme Features UL 60950-1 ◆ DIL-24 plastic package ◆ Tightly regulated output ◆ Very low output noise ◆ Short circuit protection ◆ Operating temperature range –25°C to +70°C ◆ I/O isolation 1’000 VDC ◆ Internal filter ◆ Industry standard pinout ◆ 3-year product warranty The TEM 2 series is a family of isolated dc/dc converters in a DIP-24 package. They offer tight line/load regulation and 1000 VDC I/O isolation. Standard features in- clude an internal filter to reduce reflected input ripple currrent and to guarantee low output noise. This product series provides a cost effective solution by many industrial or consumer electronics appliactions. Models Ordercode Input voltage range Output voltage Output current max. Efficiency typ.
