Here is the inspection specification of power supply adapter of cell phone jammer

What is the regular working temperature of a    cell phone jammer    ?
The air supply system, exhaust system, the shielding of the) air supply system, into the shielded room for the air supply and exhaust should be within the window through the waveguide in order to ensure overall shielded targets for reducing the drag coefficient, increasing the effective ventilated area, the project uses honeycomb-shaped waveguide window ventilation, and its technological features: all-welded waveguide is much higher than the window of the connection strength dip tin-type waveguide windows, transport assembly process will not affect its quality, to ensure that the shield in the band effect;   cell phone jammer    should be placed in different positions to ensure the shielding effect.  all-welded honeycomb core waveguide window will not weld heat affected and fusion welding open; all-welded waveguide window does not exist due to immersion tin waveguide window effects to ensure that there is too much immersion tin solder, its weight is far far less than the dip tin type; all-welded cellular high-tech welding method using waveguide window, belongs to ensure that even in the case of small honeycomb core honeycomb holes will not be blocked; all-welded honeycomb waveguide windows for high welding materials used conductivity and permeability of the material, it is an excellent screen effect; Here is the inspection specification of power supply adapter of cell phone jammer    .all-welded honeycomb waveguide waveguide windows in all forms of the lightest weight window, drag the smallest, the best shielding. Size and quantity: 300mm × 300mm including: inlet waveguide window (300mm × 300mm) exhaust waveguide window (300mm × 300mm) 4 only 2 only 2 only (3) the shielding of the power system) the shielding of the power system: power supply system mainly filter shielded. Filter is a passive two-way network is the network passive components, the many-fold, and its end is the "source" and the other side is the "load." It is not only the attenuation along the power line conducted EMI energy, but also for EMI radiation significantly inhibited. Filter with high insertion loss filter, leakage is less than 2A, reliable performance. Power filter configuration is as follows: Master the inspection standard of the power supply adapter of    cell phone jammer so that the incoming material can better conform to quality requirements of our company.i. FNF407C150 for: all the way to the main power a 380V 160A (4) the shielding of air-conditioning system) refers to the Emerson 20 kilowatts precision air-conditioning (air conditioning user purchase) of power lines, signal lines shielding the processing of each air-conditioning, including: the power cord shielded (FNF207C30) Road shielding of signal lines (SNF216D1000) out of the shielded room waveguide: Precision air conditioning pipe, tube, condensation water, water, return water shield deal with. (5) shielded cable) optical waveguide: 16 for: communication signal transmission cable shielded. 15 (6) fire protection system shielded) signal filter (SNF216D1000) smoke filter (SNF216D1000) bell filter (SNF216D1000) temperature sense filter (SNF216D1000) for the gas pipeline fire without the shielding device 1 1 1 1 (7) Security Systems shielded) signal filter (SNF211D500) shielding for video surveillance signal processing 1 (8) the shielding of the telephone line) phone filters SNF205D500 for: audio transmission shielded. 1 (9) the shielding of the grounding system) this project a joint ground, ground by the customer to complete.This specification is applicable to all power supply adapters of    cell phone jammer manufactured by our factory. Ground cable shield is grounded and grounding bolt connection, grounding resistance is less than 1 ohm. ① logic ground with 40mm × 3mm of copper ② logic to filter FNF104C50 FNF104C50 1 set 1 1 device safely filter nine, room grounding system 1, the engineering design of the DC logic ground resistance ≤ 0.9, to exchange resistance value of ≤ 1, security protection resistance ≤ 1, lightning protection system ground resistance values.
