High Power Super Capacitor Charger 1.5A 18W
with Wall adapter + 2x 400f 2.7v caps
This listing is for a fully assembled and tested super capacitor charger module that has four selectable charge modes, which are talked about below. It is very easy to use. We are selling many variants of this set. This set comes with a fully assembled and tested charger, 2x 400 farad 2.7v super capacitors, and a 12v 2A wall adapter. Check out our other variants in our store! This charger is a substantial upgrade from our last charger that charges at a mere 500mA. This charger charges at a whopping 1.5A / 18W! It charges super capacitors very fast. It can charge single capacitors, or banks of two in series. You can also put capacitors in parallel to double the capacitance. Once it is done charging, the relay shuts off, the charge circuitry and the super capacitor, or series bank become completely isolated from one another, so that there is no back-powering when the device is off. Make sure to watch the video above which offers a FULL demonstration, and read the information below. There are test points right beside the super capacitor charge terminal block so that you can use a multimeter to watch the charge if you are interested. You can also splice off of these lines and leave the capacitors connected to the terminal block. There are 8x mounting holes on the edges of the board that you can take advantage of. We also sell these in kit form for several dollars less, so make sure to have a look through our inventory!
How it works:
An on board microcontroller samples the voltage on the super capacitor, or super capacitor bank being charged thousands of times a second, and acts to limit the voltage via an on board relay. The above video will show you how to work the device. There is a 5v regulator that protects the relay and the microcontroller from damage, but the circuit is designed for an input voltage of no more than 13v. 12v 2A is nominal. This module is designed to charge single super capacitors rated for either 2.5v or 2.7v, or series capacitor banks rated for 5v (2x 2.5v capacitors in series) or 5.4v (2x 2.7v capacitors in parallel). By using only one on board SELECT button, you can choose between the following charge modes:
Charge Modes:
1) 2.5v - This mode charges your capacitor to roughly 2.42v to 2.45v. This is to ensure that you capacitor is charged to a safe level. This mode is meant for super capacitors that have a maximum voltage rating of 2.5v. Please watch the above video to see how the 2.5v charge is selected. You have to press the button until the LED blinks once. As soon as the on board LED blinks once, let go, and the relay will click on,.which means that charging has commenced to charge to just under 2.42-2.45v. The charge voltage is designed to be just under the maximum charge value of the capacitor to ensure that no damage is done to your capacitor, and do ensure that your caps have a long life!
2) 2.7v - This mode charges your capacitor to roughly 2.60v to 2.65v. This is to ensure that you capacitor is charged to a safe level. This mode is meant for super capacitors that have a maximum voltage rating of 2.7v. You have to press the button until the LED blinks twice. As soon as the on board LED blinks twice, let go, and the relay will click on,.which means that charging has commenced to charge to just under 2.60-2.65v. The charge voltage is designed to be just under the maximum charge value of the capacitor to ensure that no damage is done to your capacitor, and do ensure that your caps have a long life!
3) 5v - This mode charges a series bank of two 2.5v capacitors to a voltage of just under 5v. This is to ensure that your series capacitor bank is charged to a safe level. This mode is meant for two series super capacitors that each have a maximum voltage rating of 2.5v. You have to press the button until the LED blinks three times. As soon as the on board LED blinks three times, let go, and the relay will click on,.which means that charging has commenced to charge to just under 5v. The charge voltage is designed ONLY for series capacitor banks of 2x 2.5v capacitors. Do not charge one single super capacitor to 5v, as you will damage it! If you have questions, please do not hesitate to ask!
4) 5.4v - This mode charges a series bank of two 2.7v capacitors to a voltage of just under 5.35v. This is to ensure that your series capacitor bank is charged to a safe level. This mode is meant for two series super capacitors that each have a maximum voltage rating of 2.7v. You have to press the button until the LED blinks four times. As soon as the on board LED blinks four times, let go, and the relay will click on,.which means that charging has commenced to charge to just under 5.4v. The charge voltage is designed ONLY for series capacitor banks of 2x 2.7v capacitors. Do not charge one single super capacitor to 5.4v, as you will damage it! Youc an only use this setting if you have 2x 2.7v super capacitors in series. If you have questions, please do not hesitate to ask!
Requirements:
1) The charger requires 11.5v - 13v @ 2A minimum to operate. Minimum current consumption is 1.65mA when charging. Nominal supply voltage is supplied by the 12v @ 2A wall adapter.
This Set Includes:
1x Fully assembled and tested super capacitor charger board
1x 12VDC 2A wall adapter
2x 2.7v 400 farad super capacitors
This Set Does Not Include:
- No Voltage booster comes with this variant of the set. We have other variants that do, but this set does not. What you see in the picture is what you get.
WARNING:
The one board 8 ohm 20 watt current limiting resistors gets VERY HOT when charging. As well, the 5v on board regulator can become relatively hot as well. Make sure to be VERY CAREFUL not to burn yourself while the device is charging super capacitors. Once the charge has completed, it takes about 15 minutes for the resistor and the regulator to cool off. Please be warned, as I will not be held responsible for any burns or issues you may have at your end.
