1) Phase control
It is output type to control phase of an alternating signal according to control input signal.

This is analog type to output control angle with dividing It divides control angle non-equally according as control

2) Cycle control (fixed cycle) - Zero cross turn-on

It controls the power, which is applied into the load to repeat ON/OFF cycle like below picture with constant proportion
according to control input signal. It is easy to control the load and there is no ON/OFF noise because it turns ON and OFF
at the zero point of AC.
Usually it is used in a place or electric furnace which is not easily effected by external noise.

Remove of Case
After disconnecting all power sources supplied to the product,
remove the case.
Push the Joint part (4 points) on the right and left side of the case
with the flat head screwdriver, and disassemble the case.
When using the tool, be careful not to injure yourself.

Proper Usage
Cautions during use
1. Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected accidents.
2. Use the product, after 3 sec of supplying power.
3. Before use, set the mode and function according to the specification.
Especially, be cautious that the product does not operate when OUT ADJ. is set to 0%.
Since mode/parameter can not be changed during operation, set the mode and function after turning off the power.
4. To ensure the reliability of the product, install the product on the panel or metal surface vertically to the ground.
5. Install the unit in the well ventilated place.
6. While supplying power to the load or right after turning off the power of the load, do not touch the body and heat sink.
Failure to follow this instruction may result in a burn due to the high temperature.
7. Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power.
8. Do not wire to terminals which are not used.
9. The rapid fuse must be connected between R terminal and the power source.
10. D  o not use near the equipment which generates strong magnetic force or high frequency noise.
11. This unit may be used in the following environments.
