Let It Ripple’s mission is to use film, technology, discussion materials, and events to engage a 21st century audience in conversation and action around complicated subjects that are shaping our lives. Our experiment we call Cloud Filmmaking began by asking, what would it look like to make a film collaboratively with people around the world? Q1, Q2, and R2 may be power ripple as a power darlington transistor. D5 and R1 provide a reference voltage at the base of Q1.
220v Ac to 12v Ac then rectifying circuit and then all the above elements , but the output voltage gets around 1. It is not able to take load. It’s very good to supply an power amplifier, because the capacitor it have high voltage. Yes 12V 12A transformer can be used. D1-D4 should be able to handle that load current.
C1 should be 470uF to 1000uF per Amp of load current. 5 times load current after C1 before R1. Transistor Q1 should be be mounted on a thick heat-sink tightly. Actually I have builded in this circuit. I could not get one matter. How much is this circuit have to output voltage. If i used zener diode voltage 6.
2V then will i get output voltage 6.

Kepco, an ISO 9001:2015 company, has been designing and manufacturing electronic power supplies, both modular and instrument type, since 1946. Specializing in digital- and analog-controlled fast-programmable a-c to d-c converters, both linear and switch-mode power supply types. Digital control is supported using SCPI. Kepco products range from cutting edge, OEM and programmable switch mode power supplies to high performance, low noise, linear power supplies.
From small switchers to large, integrated systems of linear power supplies, Kepco provides solutions to the most challenging power supply requirements. LIGO systems that helped detect gravitational waves. 3, 5, 12, 15, 24, 28, 48, 125V Four 1500W models: 24, 28, 48, 125V Hot-swappable: no system downtime for maintenance. Perfect for extreme wet and hot environments.
LAN control optional, replaces standard RS 232 interface. True 1U height – full power operation with no spacing between units. 200-240V a-c input with active PFC. Wide range a-c input with active PFC. Low profile, optional cover factory installed.
FCC Class B conducted and radiated emissions. Optimized for very low ripple, noise and temperature stability in current mode. Linear power supplies are great solutions for applications where the noise of switching power supplies interferes with the operation of the load and obscures performance measurements. Built-in isolation diodes for hot swap. Enter the characters you see below Sorry, we just need to make sure you’re not a robot. Just like a drop of water in a bucket, access to clean water creates a ripple effect in a community.
Employment statistics go up immediately: we employ local laborers to build the projects, local cooks to provide them with food while they’re working, and we train local individuals to maintain and secure the well in the future. Mothers can give birth in clean healthcenters with a much lower chance of getting an infection. Children do not die from diarrhea, cholera, or other water-borne illnesses. More children can go to school: In the village of Latawken, Kenya, where we built a water system, local authorities had to build a bigger school because there were more students after there was clean water.
More of these students are girls who no longer are removed from school to help their mothers carry water when their families get too big: In Kalebuka, in the Democratic Republic of the Congo, we’ve built a well at the area’s first all-girls school. Children can grow without developmental problems that they otherwise incur from carrying such heavy loads on their backs and heads at such a young age. Women now have the time to pursue their own education and earn an income: In Pel, Mali, where we built 5 wells, one of them is at a garden owned by a local women’s cooperative. This co-op functions like a sort of savings-and-loan organization, whereby the women pool and save their money altogether.
