8W DIL package
The 8DPRW4_3 Series is high performance isolated 8W DC/DC conver-
ters. Designed with high efficiency, they allow the operating tempera-
ture range of these units to be -40°C to +85°C with industry-standard
footprint. Further features include wide 4:1 input voltage range, remote
on/off control, short-circuit protection and over voltage protection.
EN50155 approval for railway
applications
Operating Temperature Range:
-40°C to +85°C
Under voltage lock-out circuit
Over voltage protection
Over load protection
Short circuit protection (SCP)
Remote On/Off
These converters are well suitable for battery operated equipment,
measurement equipment, telecom, wireless network and industry con-
trol systems. Everywhere where isolated, tightly regulated voltages and
compact size are required.
