USBHUB with mobile hard disk is what reason? With other digital products are very good, you can quickly read the data How to solve, seek guidance
It is estimated that the reasons for lack of power directly to the mobile hard drive to the computer under the test
YJV is copper core XLPE insulated, PVC sheathed cable, laying in the room, tunnels and pipes, can not bear the mechanical pressure Core long-term allowable operating temperature shall not exceed 80 degrees Celsius, the ambient temperature of not less than -15 degrees Celsius under the conditions of laying without heating VV cable should not be used at -15 ℃ Cross-linked polyethylene insulated cable (YJV) with the cross-section of the current carrying capacity than the VV cable, and YJV cable mechanical properties than the VV cable, the application range than the VV cable wide Second, the two in the production equipment and process manufacturing are also different: VV for the plastic cable, YJV that cross-linked cable, the insulation performance is better than plastic cable YJV only made a cross-linking treatment on the insulating material to improve the heat-resistant temperature, while VV did not YJV cable operating temperature of 90 degrees, while the VV is only 70 degrees, with the cross-sectional area YJV cable carrying capacity VV class cable conductor running the maximum rated temperature of 70 degrees Celsius, short circuit (duration less than 5 seconds) the maximum temperature does not exceed 160 degrees Celsius YJV class cable conductor running the maximum rated temperature of 90 degrees Celsius, short circuit (duration less than 5 seconds) the maximum temperature does not exceed 250 degrees Celsius YJV is better than VV in the long run (long life), but more expensive than VV From the maximum allowable short circuit to see: YJV is 250 degrees, VV is 140
It is estimated that there is no reservation, even the two worthless speakers are not installed, how could reserve line
If you simply compare the two, there is no doubt choose Olympus. As a single power, PM1 performance more than P. the camera's two most important parameters are photosensitive components and lenses: PM1 on the sensor is 4: 3 system, P510 is the smallest of 1: 2.. the quality of PM1 to P510 The lens on the lens, the P510 on the big zoom lens performance can not and Oba's hedge (should be 14-42 darling jealous German garden spring) compared to being thrown out of a few streets; so do not hesitate , Select PM. P510 in addition to the appearance of SLR, its performance and SLR side are not accounted for.
