Description:
Oscillation mode: Decompression of linear compressor, ac voltage output voltage passes through less than 3 v rectifiers and filters.
Through such double input 12v, 12x1.414 16.968v, output voltage can be 16.968-3v 13.968v
Recommendations: Input voltage (Rectification voltage smoothness means replacing alternate voltage, ac input is rectified and filtered to 1.414 times, reclamation and filtering if the input voltage of 12 v ac is reclaimed and filtered after 12x1.414 16.968 v) At least above output voltage of 3 v, but not too high, too much pressure only increases power consumption by 317/337, chip calories, output currents can also be lower, for example, the voltage of the input voltage after rectifiers and filters is 12 v, output adjustment to 5 v, compressor lowers pressure drop higher than chip 12-5 7v, if current time
For 0.5a, power regulator 0.5x7 3.5w, higher power, the more serious the heat is.
Pcb fr-4 plates with military grade single board material, plate and some stability tolerance parameters, material performance is very difficult, some of these other relatively cheap price lists are interested. Direct printing of plate pcb parameters, direct welding without reference to circuit diagrams, very convenient.
Note:
- double-sided spinning, process buffer pads to increase tin and tin spray pads, repeatable deweldability, it 's not easy to get off. (The decline in folding conditions refers to non-human causes)
- once not likely to bend, plaques change over time and bending.
- impedance is more stable and reliable.
Product specifications:
Input voltage: Ac 5v ac 20 v (Ac double input only)
Dc output: 1.3-25v.
Current: 1a.
Size of pcb plate: 6.2x5.9cm/2.44x2.32
Number: 1 set
Note:
Due to manual measurements, please allow 1-3 mm error. Please make sure you don 't mind before bidding
Due to differences between different monitors, the picture may not reflect the actual color of the project. Thank you
