UcPure (MkIII and Quad) ultracapacitor power supplies

UcPure  MkIII

Introduction
UcPure MkIII is a pure ultracapacitor power supply. It makes use of the 3000F or higher c apacitance ultracapacitor pack to achieve an ultimate power supply performance. Because it is a pure passive power supply, there will be no feedback a nd no active components involved when it’s turned on. At the pure output m ode, only the pre charged ultra capacitor pa ck will be applied to the load It’s also capable of delivering up to 1000A dynamic current with less than 0.5 8 mOhm internal ESR ( continuous output mode, decided by the 30 00F ultracapacitor s pack). It could be so far the best low noise and ultra high dynamic power supply in the real world. Sound quality of sensitive audio applications such as low jitter clock oscillators, DACs, FIFOs and m any other circuits will be benefit e d from th is UcPure MkIII power supply. UcPure MkIII can be setup for 3.3V, 5V(default) and 15V configurations.
UcPure MkIII equipped with a SYNC charging function to be able to re charge the ultracapacitors during music stops.

Specification s and Highlighted Features

• Pure ultracapacitor power supply
• Ultracapa citors work in class A mode which current going only in one direction.
• Output can be configured to 3.3V , 5V ( and 15V
• Has both switched and continuous (great for clock oscillators) outp uts
• Outputs are 100% isolated from charger , input and other circuit when it is turned on at pure mode
• Has built in on/off control switch (on board or external)
• Has an isolated on/off control management chain that can be set up in a group of power supplies.
• Optical isolators are used for all internal operating logics.
• Can use 9V to 20V DC input for 3.3V/5V configuration and 18V 20V DC input for 15V configuration.
  AC 9V 12V input is also possible for 3.3V/5V configuration
• Pre Charging current has 3 A (default) and 1.5A two settings to be suitable for different input power supplies.
• Built in pr otection scheme to prevent ultracapacitor from exhausted and low output voltage
• Dynami c output current: up to 1000A (d ecided by the ultracapacitors
• Output ESR: Less than 0.5 8 mOhm (3.3V or 5V configuration, decided by the ultracapa citors)
• Output noise: Decided only by the ultracapacitors
• Heavy duty design for 24/7 operation

#41F UcBalancer could be the best balance/protection board to work with

New features:
1. Two 3000F ultracapacitor groups in parallel, reducing the output ESR to the next lower level which has never been reached before. Noise was also reduced by 1/sqrt(2) in principle.
2. New dual PCB architecture to completely eliminate the wires between UcPure and ultracapacitors, thus significantly improving the performance. Because the resistance of the wires can be even higher than the ultracapacitor ESR itself.
3. The pure time is double, the dynamic current is also double.
4. Balancing functions are integrated on PCB, so no longer need external balancer/protection boards.
5. Both horizontal and vertical mount brackets.
6. 5V or 3.3V, jumper configurable.
7. 5.3A or 8.1A fast charging current, jumper configurable
8. Optimized to 12V AC input
9. Double copper thickness, four layers PCB design to ensure the lowest ESR performance
10. Two groups of switched and continuous output to make it easier to share this great power supply with different circuits of the system
11. So far the best power supply for clocks and DACs to improve the sound quality.
11. Very easy to assemble, just screw and play.
12. Many other improvements

Note:

1. Please cut the connector pins shorter at back side of the PCB if they are too long. Otherwise, there will be a risk to touch the ultracapacitors and make a short circuit.
2. When using DC input such as a standard laptop power adapter, the grounding pin (if there is any)  of the power cord must be removed to avoid ground loop or possible short circuit.
3. Ultracapacitors are not included. Recommended ultracapacitor P/Ns are:
   XL60-2R7308T-R
   XL60-3R0308T-R
   TPLH-2R7/3000SL60138
   TPLH-3R0/3000SL60138
