Description
Item specifics
● Condition : New
● Brand : Jolooyo
● Type : WZ-68/69
● Country/Region of Manufacture : China
● To Fit : Amplifier
WZ-68 High quality ultra-compact precision adjustable voltage regulator, can directly replace the fixed three-terminal positive regulator 78xx series
WZ-69 High quality ultra small precision adjustable voltage regulator, can directly replace the fixed three-terminal negative voltage regulator 79xx series.
Adjustment tube for the country half of the dismantled LM317/LM337, because of the new environmentally friendly package, the quality has decreased, the dismantled heat sink is thicker, the output current capacity is stronger, care about this cautious purchase.
Please note that the purchase of positive and negative power, finished products do not come with heat sink!
Finished product size about: length 42mm, width 20mm.
Maximum height of about 16mm, easy to install into a short chassis or rack above the original PCB.
Rectifier part of the introduction of Marantz grounding concept, so that the ground interference is greatly reduced.
②The design principle is small size for easy installation in the machine.
The design principle is small size to facilitate the installation in the machine, ③ Pay full attention to the good decoupling.
Voltage adjustment with precision multi-turn adjustable resistors, leaving the resistor mounting position (from the performance considerations we recommend that the required voltage is adjusted with a fixed resistor instead).
⑤The output of this board can be adjustable from ±1.3V to 42V (please pay attention to the voltage difference and capacitor withstand voltage if you need wider voltage).
From the regulator performance and power consumption considerations, the input DC is slightly larger than the required output DC can be, such as the need for DC9V out of the available DC12V into.
