The product is divided into two types: finished product and toolkit. Please note when ordering, and the default is finished product.
DIY kits need welding by yourself
Description:
1. line to the Swiss STUDER power line modeled, the output accuracy is very high, low ripple
2. finishing tube for the 5A rectifier, NOVER gold capacitor, the output tube for the ON tube Wang MJE15034, board reference voltage regulator using dual op amp TL072
3.Input voltage range: dual 9V to double 24V (4-wire transformer) Output: Positive and negative DC 5V to DC 28V or dual DC 5V to double positive pressure 28V, with short circuit protection. Output current up to 2A
Directions for use:
The board regulator has 3 gears, which are:
H (high) The output voltage is more than 20V and the highest is 28V. It is suitable for the voltage level circuit of discrete components.
M (medium) 12-18V look suitable for preamplifier use
L (low voltage) output 5V-9V appearance, suitable for DAC power supply
After setting the gear, the adjustable resistance of the trimming board has reached an exact value.
The corresponding resistance of H is 33K M. The corresponding resistance is 12-18K (the higher the resistance, the higher the voltage regulation, but the lowest voltage will also increase). The corresponding resistance of L is 3K3-6K8.
When you want to use 2 sets of independent single and double DC output, such as 1 set of 5V 1 set of 9V, you can directly output from the green terminal.
If you want to set the positive and negative power supply to the op amp, you can short circuit the fly-wire above the gold-plated pad, and then output a positive voltage from VCC. It is easy to ground the VSS to output the negative voltage.
