Figure 2. Connection

Input Vin
Terminal Ref: Connect DC power supply to 1& 2.
The input voltage range is 7 to 22V. Any type of DC power supply is acceptable.
A constant voltage source, AC DC adapter, battery, or solar cell (PV) etc. for experiments can also
be connected.
f the impedance of the connected power supply is low enough, an inrush current will be generated
to the charging module.
Ex. n the case of a 13V-5mΩ lead-acid battery, about 10A-0.5msec
Output Vout
Terminal Ref: Connect an supercapacitor to 3 & 4.
When installing, the supercapacitor side should be 0V
and no voltage should be applied to the input section (power supply is not activated).
Charging other than the supercapacitor is the responsibility of the customer.
On/Off Connector
Terminal Ref: Connect the supplied harness to 5 and connect it to the fault detection terminal of
the supercapacitor module.
* This product will not start if the harness is not connected.
* Refer to "7. unctional Description" for the startup method without the dedicated harness.

6. How to Change Output oltage Mounting Option
The output voltage can be set by jumpering any of the following
mounting points R15 to 17.
Mounting should be limited to one location only.
Any changes from the default settings should be made by thecustomer.

7. Functional Description
Reverse voltage protection to input section
f a reverse voltage is applied to Vin, the fuse inside the circuit will blow to protect the device.
n this case, Vin(+) of the input section becomes electrically open.
Surge Protection for Input Section
A varistor (surge absorber) is attached to the input section to protect against pulsed overvoltages.
The varistor operating voltage is 27V.
Reverse voltage protection to Output section
Vout(+) has a reverse current protection diode connected between the power supply circuit and the output
terminal.
This function prevents current from returning from the charged supercapacitor.
t also functions while the charging module is not running.
Overcurrent Protection
This product has built-in overcurrent protection, but does not have an automatic shut-off function.
This is because, when charging an supercapacitor, a pseudo short-circuit current appears to flow continuously.
Overvoltage Protection
The overvoltage function of this product is only the B function of the power supply. t does not provide doubleprotection.
Overheat Protection
This product does not have an overheat protection function. n the development and evaluation of the product,
operation was verified under the following conditions:
1) Continuous operation at room temperature of 25°C, natural air cooling, and no airflow
2) Continuous operation at 70°C, inside a thermostatic chamber, with forced convection
On/Off Function
With a voltage input of 7 V or more to Vin, the output is enabled when there is a short between connectors Pin 1and 2 of J5.
When the supplied harness is connected, the signal state with the supercapacitor module is normal-short.
f an abnormality is detected on the charging module side, it becomes Abnormal-Open and the output is stopped(SW stop of power supply).
To switch On Off by another method, follow the procedure below:
1) Connect a jumper resistor to R27, which is unmounted at shipping.
2) Turn on/off the pin-to-pin connection of J5 with a switch, etc. In this case, add a chattering remover.
