Description

The BWA40 Series are isolated 40W DC/DC converters.

Designed with highly efficiency, allow the operating

temperature range of these units to be -40°C to +85°C in

a 50.8×50.8×10.2mm shielded metal case. Further

features include wide 2 : 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

Adjustable Output Voltage

Optional Heat-sink

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.

Material: Aluminum

Weight: 19g (0.67oz) (without converter)

Note:

The product label on converter has to be

removed before mounting the heat-sink.

For volume orders, converters will be supplied

with heat-sink already mounted. Please contact

factory for quotation.

Separate heat-sinks are only available for

prototypes and small quantity orders.
