Operation and Function
Front
Control method selection
1) Phase control
It is output type to control phase of an alternating signal according to control input signal.
2) Cycle control (xed 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.
● Equal division type of phase according as control input
This is analog type to output control angle with dividing
equally according as control input signal. It shows power
characteristic as (Fig. 1) and it might occur over power and
lack power at point middle of control input.
● Equal division type of power according as control input
It divides control angle non-equally according as control
input signal then make power curve linearization, so it
becomes possible to output the power, which is proportioned
control input as outputting (Fig. 1).

※To change control cycle, please change JP1 and JP2 of PCB as below.
OUT ADJ. (output limit) (0 to 100%)
This function will be [Control input (%) × OUT ADJ. (%) =
Output] and it controls the power supplied into the load.
Although control input is 100% (5V or 20mA), the output is
the 50% which is proportioned with OUT ADJ. When not
using OUT ADJ. function, please make set value 100%.
※This function must not be used in ON/OFF control
method.
SOFT START (0 to 50 sec)
This function protects the load in cases that the set
temperature is high, such as controlling the load (platinum.
molybdenum, tungsten, infrared lamp, etc.) in which inrush
current ows when power is supplied, or showing large
width of temperature rise during initial operation.
SOFT START set time (T) is the required time that output
reaches to 100%, and it is differentiated by OUT ADJ.
set value. For example, SOFT START is set as 10sec
and OUT ADJ. is set as 70%, it takes 7 sec to reach goal
output.
[Set time (T)×OUT ADJ. set value (%)=10 sec×0.7=7 sec]
If increasing the OUT ADJ. before output reaches to
goal output, it delays as much as the value, multiply of
increased value (%) and SOFT START set time. When not
using SOFT START function, please make set value 0.
※This function must not be used in ON/OFF control
method.
OUT display
This is LED lamp to display the status of output and will be getting brighter according as output.
(0%: min. LED light, 100%: max. LED light)
3) ON/OFF control-Zero cross
This function is when control input is ON, output is 100%.
When it is OFF, output is 0%.
It is the same function as SSR (Solid State Relay).
(It always turns ON/OFF at zero point of AC.)
※OUT ADJ. and SOFT START function are not
available in ON/OFF control method.

Proper Usage
Temperature Derating Curve
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 specication.
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. Do not use near the equipment which generates strong magnetic force or high frequency noise.
11. This unit may be used in the following environments.
①Indoors (in the environment condition rated in 'Specications')
②Altitude max. 2,000m
③Pollution degree 2
④Installation category III
E.g. 1) When controlling by limiting the power at ON/OFF
in phase control and cycle control method.
For example, if it needs to control 80% output when
it is ON, 24% output when it is OFF, please keep
below.
Firstly set OUT ADJ. as 80% and connect external
adjuster and external relay contact switch as the
gure then set external adjuster as 30%.
● When the External contact signal is ON
: 100% (contact input)×80% (OUT ADJ.)=80%
● When the External contact signal is OFF
: 30% (adjuster input)×80% (OUT ADJ.)=24%
E.g. 2) This is how to control 0 to 100% without
external adjuster in phase control and cycle
control method.
It is possible to control 0 to 100% by turning
OUT ADJ. in state of connecting terminal 2
and terminal 3.
