Application scope

     JBKZ、BKZ series rectifier device was made from BK combination of transformer and rectifierelement.Transformer primary side voltage is applide to 220V or 380V AC 50Hz power supply,pay through the transistor retifier component side rectifier output DC.For battery charging,as well as AC variable DC prwer aupply used in the device.

Normal operating conditions

1、ambient air temperature
a.the maximun ambient air temperature doe snot exceed+40℃
b.the surrounding air temperature of 24h does not exceed+30c
c.the average ambient air temperature of 24h does not exceed-5 c
2、elevation:installation location no more than 2000 meters above sea level.
3、atmospheric conditions:air relative humidity in the ambient air temoerature is+40℃ less than 50%,at a lower temperature can have a higher relative humidity average maximun relative humidity of 90%,while the monthly average minimum temperature of+25 ℃ , and taking into account changes in thmperature occurred in the product condensing on surface.
4、pollution levels Pollution grade 3.
5、the installation category(overv oltage category ):installation category Class m
6、power supply voltage power supply voltage to allow deviation of +50%
7、the installation conditions: lnstallation in the absence of severe shock and vibration impact on the local.
