Description: Printed Circuit Board (PCB) ONLY. This printed circuit board component and the resulting high voltage power supply are intended for experienced persons, and the supply produces potentially dangerous voltages. The schematic and a representative component list will ship with the PCB. It is not available beforehand.. No other components are included in this auction. ----------------------------------------------------------IMPORTANT!! We have received information that appears to indicate that there are fake LR8N regulators on the market. Be careful and test your LR8N according to the LR8N datasheet before integrating the regulator into your circuit. We have obtained a limited supply of L8RN's from a reputable supply source. Please see our listing with item number 204448561298----------------------------------------------------Unfortunately our pricing structure does not allow discounts for multiple purchases on this item. PCB dimensions: 3.5" x 2.5" For a 100-330VDC regulated variable power supply using this PCB, we have employed the following components. Your choice of components may be different. The Antique Wireless Association is not endorsing any particular component or vendor. C1: 100μF 450V electrolytic capacitor C2: 1μF 450V electrolytic capacitor C3: 22uF 450V electrolytic capacitor D1-D5: 1N4007 diode HS1: Depends on your overall design, Ohmite FA-T220-38E fits on PCB PCB: AWA Rev 6 8/2020 Q1: TIP50 NPN power transistor Q1 Mounting Kit: Like AAVID 4880MG R1: 2k, 1/4-watt resistor R2: Used for fixed output voltage only; not used with VR1 R3: 150k, 2-watt R4: 160k, 1/4-watt resistor T1: HV power transformer, like Triad VPS230-110 U1: LR8N3-G 3-terminal adjustable regulator VR1: 500k 1/2-watt, like Bourns 3296Y-1-504LF Operational load current depends on your power transformer and TIP50 power dissipation. The PCB allows for an on-board or remote variable resistor (VR1) for voltage control. The PCB allows for a fixed output voltage, using R2. The PCB allows for a remote transistor (Q1) and custom heat sink (HS1). This auction is for the printed circuit board (PCB) only. There are no other components included in this auction. The Antique Wireless Association museum is run by volunteers. Our "work day" is Tuesdays. Your item will be shipped then. If there are any questions please feel free to contact us by return email. We try to check the email at least once a day.
