Dual Rail Power Supply PCB Power Supply, Rectifier /Filter PCBUsed for Audio Amplifiers, or other applications requiring a double ended supplyPrinted Circuit Board + Instructions (6 page) Lot Size: 1 units See other listings and lot sizes for this item See other Printed Circuit Boards This PCB builds a scaleable supply for maximum voltages of +/-120V and max current 20 A.- includes 6 page instruction leaflet - High quality FR4 double-sided, plated-thru holes, with conformal coating solder mask. - Pre-tinned soldering pads. - Provides for 2 Inrush Current Limiters, to safely charge capacitors, and better protection of amplifier - RC snubber to prevent high frequency oscillation - uses Fast TO220 2 or 3-pin Schottky Rectifiers, for lowest voltage drop: 0.2V - Top side ground plane. - Provision for either 2 large electrolytics (10,000+ uF for each rail), or multiple smaller capacitors (up to 5 per rail) in parallel, for reduced ESR, and low profile form factor. - accommodates either 2-secondary transformers (with individual rectifier bridges for each) or center-tapped secondary, with single or parallel-connected bridge. - Power resistors for slow and safe discharging of filter capacitors. - Dimensions: 3.6" x 3.8" 92mm x 97mm below: suggested schematic of power Supply. Some components optional. Transformers with 2 secondaries: Feed each secondary to its own rectifier, and combine rails post-rectification, OR tie the 2 center legs of the secondaries together to form a center tap. Transformers with single center-tapped secondary: use a single bridge, or both bridges in parallel. Takes Schottky or UFR fast recovery rectifiers in TO220 2 or 3 pin packages Only the PCB and 6 page leaflet is provided, no components included.
