The BVA30W Series are isolated 30W DC/DC
converters. Designed with highly efficiency, allow the
operating temperature range of these units to be -40°C
to +85°C in a 50.8×40.6×10.2mm shielded metal case.
Further features include wide 4 : 1 input voltage range,
remote on/off control, short-circuit protection, over
voltage protection and over temperature protection.
Shielded Metal Case with Insulated Baseplate
Lead Free Design, RoHS Compliant
Industry Standard Pinout
Adjustable Output Voltage
Applications
Customer Design Available
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.
