BOTHHAND ENTERPRISE INC.
Features
Wide 2 : 1 Input Voltage Range(4.5~9V,9~18V,18~36V,36~75V) Input / Output Isolation Voltage: 1.5K Vdc Extended Operating Temperature Range: -40°C to +85°C Output Short Circuit Protection: Continuous & Auto Recovery Over Voltage Protection: Clamp Mode Description Shielded Metal Case with Insulated Baseplate The BOA5 Series are isolated 5W DC/DC converters. Designed with highly efficiency, allow the operating temperature range of Lead Free Design, RoHS Compliant 24pin DIP Package with Industry-Standard Footprint these units to be -40°C to +85°C in a 24 pin DIP package with industry-standard footprint. Further features include wide 2 : 1 Customer Design Available input voltage range, short-circuit protection and over voltage protection.
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.
