Product Description
 
The newest WHB series DC/DC Converter developed by SunYuan, It uses wide isulation distance and new isolation material design and comply with the relevant safety regulations of the external RS232/RS485 bus control communication interface in the national electric industry DL/T 614-2007 multi-function energy meter protocol standard, It is a high-isolation & anti-pulse electrostatic dc-dc converter for the intelligent control of the instrumentation equipment bus Ethernet interface commonly used in the electric power medical industry such as power load management terminal, multi-function electric energy meter, blood analyzer, life monitor etc. The SIP12Pin high integration and small size package technology enables the module to have self-recovery overload short-circuit protection and regulated output function.
 
After the electric medical equipment is added to the WHB series dc dc converter, the safety barrier isolation voltage value of the external bus Ethernet (RJ45/RS232/RS485) interface terminal of the instrumentation equipment reaches 10KVDC high isolation and 8KVAC anti pulse group electrostatic protection due to the high isolation between the input and output terminals of the module power supply. Therefore, the WHB series of high isolation dc dc converter can make the equipment and equipment resistant to EMC upgrade and can pass the safety inspection of the electric medical industry.

Product pressure test notes and test methods:
1、As shown in Figure 1: According to the product isolation voltage specification and set the rated high voltage value, please pay attention to personal safety when testing, beware of electric shock!!!
Test conditions: room temperature TA = 25 ° C, humidity <75%
2、 The pressure test operator must wear rubber-insulated gloves and a rubber insulation pad under the seat to prevent high-voltage electric shock.
3、The pressure tester instrument must be grounded reliably and should not be tested in high temperature, humid and dusty environments.
4、The pressure tester must ensure that the high voltage output is “0” and “reset” when connecting the measured object.
5、Do not touch the test object, test line or high voltage output when the instrument is in the startup state or before the test high voltage is released.
6、The product pressure test test method as shown in Figure 1: shorting the input and output pins respectively, and adding isolation voltage between the input and output terminals (DC or AC peak, according to the isolation voltage given by the product), test 1 minute.
7、According to the standard of pressure test, the withstand voltage value is gradually increased from 0, and it is adjusted to the set maximum and maintained at the highest withstand voltage for one minute.
8、The Pressure test itself is a destructive test. The fewer times you should do the better, if the customer needs to test multiple times, the general requirements are: the first time according to the value of the specification, the next time should be correspondingly reduced test the voltage, otherwise the product will be damaged during multiple tests.
