Emerson EPW30 48A Power Supply Module 48V 30A Direct Transfer


Emerson EPW30-48A communication power rectifier module 48V / 30A direct transfer ​ 


Description of EPW30-48A

The power module can complete the conversion from AC to DC, the 90Vac~290Vac input can work normally, the rated output is 53.5VDC, and the output voltage can be adjusted by the power monitoring module. The power supply has functions such as overcurrent protection, output overvoltage protection, and overheating protection. The width of the rectifier module is 103mm, the height is limited to 2U, and the depth is 243mm. The rectifier module is equipped with a fan to dissipate heat, and the rectifier module is designed with an air duct after the forward wind.


The product design complies with IEC61000-4-2, -3, -4, -5, -6, EN55022 CLASS B conducted radiation requirements;


Safety requirements comply with UL60950, EN60950 standards, and have passed TUV/CE/UL certification.EPW30-48A rectifier module is suitable for small program-controlled switches, access networks, transmission equipment, mobile communications, satellite communications ground stations, microwave communications power supply, and can also be used for power supply for other communications equipment.
