Description
Continuous & Auto Recovery
The BOB5 Series are isolated 5W DC/DC converters. Designed
Over Voltage Protection: Clamp Mode
with highly efficiency, allow the operating temperature range of
Meet EN55022, Class A (Radiation)
these units to be -40°C to +85°C in a 24 pin DIP package with
Shielded Metal Case with Insulated Baseplate
industry-standard footprint. Further features include wide 2 : 1
input voltage range, remote on/off control, short-circuit protection
Lead Free Design, RoHS Compliant
24pin DIP Package with Industry-Standard Footprint and over voltage protection.
Customer Design Available
Applications
These converters are well suitable for battery operated
equipment, measurement equipment, telecom, wireless network,
Industry control system, everywhere where isolated, tightly
regulated voltages and compact size are required.
Technical Specification All specifications are typical at nominal input, full load and 25°C unless otherwise stated.
