The power supply for electric load management terminal such as RS485/RS232/RS422/USB/IEEE1394
Data:2008-5-21

SUNYUAN WRF series High isolation DC/DC Converter and two-wire 4-20mA isolated amplifier are widely used in electro-manage terminal.

VD/WRF/WRE series DC/DC Converter,output Automatic Recovery and short circuit protection.Patent No.: ZL 200420042857.1At present,these series pass 10KV isolation anti-static test.They are widely used in electric power instrument.

VD/WRF/WRE series DC/DC Converter,adopt ceramic board,printing resistance,meeting technicl requirements for industrial grade products,humidity,wide range temperature and other poor environment.SIP single-line and DIP dual ®Cline package.They are ideally suited for ground interference control,RS485/RS232/RS422/USB/IEEE1394 communication interface power isolation and converter,anti-static,isolation.

ISO 4-20mA Current Loop Isolation Interface IC provides signal receive and transmittal on a single chip. The ceramic hermetic hybrid package contains an electromagnetic coupled converter and current modulate.The very low input equivalent impendence allows the input voltage can be up to an ultra-wide range (7.5V~32V), so that it is able to meet the requirements for no distortion in long-distance signal transmission under the circumstance of no outside connecting power. The internal ceramic PCB, printed impendence and new isolation technologies allow the IC for the 3KVDC insulated voltage and meets the industrial level for the extremely poor temperature, humidity and shaking conditions. These specifications make the ISO 4-20mA Current Loop Isolation Interface IC very easy to use,weldable to PCB and DIN 1x1/DIN2x2 Rail-mounted.
