changes. It may cause a failure, fire, or electric shock.
Use and store in a dust-free place
Do not use or store in a dusty or sandy place. It may cause a failure, fire, or electric shock.
Do not touch the port
Do not touch the port during connecting or disconnecting. It may cause an electric shock.
Do not damage the lead wire
A damaged wire may cause a failure, fire, or electric shock.
Do not touch the tip of the lead wire and the terminal
It may cause an electric shock.
Do not touch with bare hands when damaged
In case of this product being damaged, stop using it immediately. Since a glass substrate is used,
and if the product is used as it is, the damaged parts or debris may cause injury or damage to the
human body. Also, since this product contains electrolyte, if it leaks, touching it may cause skin
irritation. Be careful not to touch it with bare hands. In case the electrolyte gets into your eyes or
mouth, immediately rinse with water or lukewarm water and seek medical advice.

Do not place in an unstable place
Dropping it may cause injury.
Do not push with strong force. Do not install with strong force
This may cause damage such as breakage of the glass substrate, resulting in injury.
Charge the LIC by following this guide
Charging the LIC by another method may cause a fire or electric shock.
Do not overload
It is recommended to add a protection circuit if necessary.
Do not repeat rapid charge and discharge. Do not apply ripple current
This may increase internal resistance or reduce the LIC capacity.
Do not touch the port during connecting or disconnecting
It may cause an electric shock.
Do not apply static electricity
It may damage the IC on the circuit board. Handle the circuit board with sufficient measures
against static electricity.

This power module consists of a high efficiency DC/DC converter, a lithium ion
capacitor (LIC), and a dye-sensitized solar cell (DSSC). A constant voltage output
of about 3 V is available even without lighting. You can evaluate whether it is
possible to replace existing batteries with dye-sensitized solar cells without
designing complex circuits.

Output port
The connector with three lead wires: red, black, and orange, will
be connected. The meaning of each color is shown below.
Red : 3V output
Black : ground
Orange : direct output from LIC for voltage monitoring purpose*
When the LIC voltage drops to 3 V, the over-discharge protection
function works.
* Conductor may not be exposed at the tip of orange lead wire to avoid
contact with other wires. Please remove the insulation before use.
Caution
Orange lead wire is connected to the positive electrode of the
LIC. Don’t short. Don’t pull out more current than specified.
Insulate the tip of unused lead wire.

How to use
○This module employs Taiyo Yuden LIC1235RS3R8406. Before use, please
read and understand its manual well.

How to assembly
（1）Connect the red and black lead wire to your device.
（2）Insert the connector into the port of the circuit board.
（3）Turn on the ON/OFF switch.
If the red lead wire shows a voltage less than 3 V before connecting to the device, LIC charging
may be inadequate. In that case, please charge the LIC according to the charging method
described later. When the LIC is charged over than 3.3 V, 3 V output will start. Voltage between
orange and black lead wire shows the voltage of LIC
（4）Please keep the power generation area exposed to light.
Maximum output is DC3.0±0.2 V / 100 mA (typ)
Maximum inrush current is 185 mA (typ).
When power supply doesn’t start, check the LIC voltage by the orange lead wire. If that is
inadequate, charge the LIC according to the charging method described later.
LIC is charged before shipment. Do not short the positive terminal and the negative terminal
of the LIC. It may cause an electric shock, burn, injury, and malfunction.

How to charge LIC
When LIC charge is inadequate, charge by DSSC.
（1）Remove the connector from the port.
（2）Turn on the ON/OFF switch.
（3）Keep the power generation area exposed to light.
NOTE) Charging time can be reduced under bright area, for example under a fluorescent light (2,000～5,000 lx).
Make sure that the entire power generation area is exposed to light as much as possible
so that it can be charged efficiently.
Do not charge the LIC other than the above method. It may cause an electric shock, burn,
or injury. It may cause a failure by electrolyte leakage, heat, smoke, explosion, or fire.
Charge the LIC by this method when overdischarged. Estimated time to re-output is as
follows. It depends on model number.
200 lx : 50～70 hours (FDSC-DSA4FGC)
2,000 lx : 4～6 hours (FDSC-DSA4FGC)
5,000 lx : 2～3 hours (FDSC-DSA4FGC)
How to storage
（1）Turn off the ON/OFF switch.
（2）Remove the connector from the port.
（3）Please keep away from places with high temperature and humidity.
（4）For long-term storage, charge the LIC once every six months. It may be overdischarged due to
leakage current.
Be sure to follow the storage method as the characteristics may change such as capacity
reduction.
Make sure that the terminals do not short during storage.
