ø30 ø30 Series Instructions

Installation of LED Illuminated Units

1. Note the polarity for wiring when connecting to DC-DC

converter unit.

Terminal No.

Polarity

Positive

Negative

2. Transformer units are recommended for use in areas

subjected to noise.

3. Notes for Pure White LED Lamps

•Do not use the pure white LED outdoors, otherwise it will

lead to the degradation of brightness and color. Do not

remove or apply shock to the cap on the pure white LED

lamp, otherwise it may break or damage the cap.

•For the pure white LED, use a white lens. The illumination

color will be dull if a different color is used.

Notes on LED Illuminated Units

LED lamps consist of semiconductors. If the applied

voltage exceeds the rated voltage, LED elements may

deteriorate due to overheat, resulting in significant

decrease in luminance, hue change, or failure of lighting.

Also, if an extraneous noise, transient voltage, or transient

current is applied to the circuit, similar effects may occur.

When using LED lamps, observe the following instructions.

Rated Voltage

The LED lamps are rated at 6V, 12V, or 24V AC/DC, and

can be used within ±10% the rated voltage of either AC or

DC.

DC Power

1. Switching power supply

Regulated voltage from switching power supply is best

suited. Make sure to use within the rated voltage of the

LED lamp.

2. Rechargeable battery

Note that the battery voltage may exceed the rated volt-

age of the LED lamp while the battery is being charged

and immediately after the charging is complete. Be sure

to use the LED lamp on a voltage of ±10% the rated

voltage.

3. Full-wave rectification

Since the LED lamp is AC/DC compatible, a diode

bridge for rectification is not necessary. If the LED lamp

is used on a full-wave rectification current through a

diode bridge, the rectifier diodes will reduce the voltage,

resulting in lower luminance.

4. Single-phase half-wave rectification

This is not suitable for the power source of LED lamps.

Use constant-voltage DC power.

Noise

LED elements deteriorate due to extraneous noise, result-

ing in significant decrease in luminance, hue change, or

failure of lighting. When such effects are anticipated, take a

protection measure shown below, such as RC elements or

a surge absorber.

Countermeasures against Dim Lighting

1. Leakage currents through the transistors or a contact

protection circuit may cause the LED lamp to illuminate

dimly even when the output is off.

2. When the LED lamp is illuminated by a transistor output,

take the following measure.

[Circuit Example]

Connect shunt resistor R in parallel with the LED lamp.

Io: Leakage current when the output is off

R: Shunt resistor
