1.Introduction:
It is a LM317LM337 three-terminal positive and negative adjustable double three-way rectifier filter stabilized power board voltage regulating module.
2.Feature:
1>.Precision voltage regulation.
2>.Buck and regulator modules.
3>.Dual-triple rectifier filtering.
3.Parameter:
1>.Input voltage: ≤AC 20V
2>.Output voltage: ±1.25~30V
3>. Output current: approx. 500mA
4>. Work Temperature: -25℃~85℃
5>.Work Humidity:0%~95%RH
6>. Size: 78*48*26.8MM
4.Note:
1>. Branches 1 and 2 use the LM317 and LM337 to form a set of positive and negative voltages, each of which allows for individual regulation.
2>. Branch 3 uses LM317 to form a separate power supply and adjust the voltage value separately.
3>.The voltage output size depends on the input voltage value.
4>.If the transformer is a set of dual power supplies, you can short the two jumpers JP1 and JP2 on the reverse side of the circuit board as illustrated, and the output terminal can get a total of 3 outputs.
5>.If the load is too heavy and there is an overheating situation, it needs to be stopped immediately.
5.Package:
1pcs Filtered and regulated power board.
