Spacing
※
When installing multiple power controllers, please
keep space at least 50mm in horizontal and 100mm in
vertical between power controllers for heat radiation.
While supplying power to the load or right after turning
off the power of the load, do not touch the body and
heatsink. Failure to follow this instruction may result in
a burn due to the high temperature.
High Temperature Caution
Safety Considerations
1. Fail-safe device must be installed when using the unit with machinery that may cause
serious injury or substantial economic loss. (e.g. nuclear power control, medical equipment,
ships, vehicles, railways, aircraft, combustion apparatus, safety equipment, crime/disaster
prevention devices, etc.)
Failure to follow this instruction may result in re, personal injury, or economic loss.
2. Install on the device panel, and ground to the heat sink or bracket separately.
Failure to follow this instruction may result in electric shock or re.
3. Do not connect, repair, or inspect the unit while connected to a power source.
Failure to follow this instruction may result in electric shock or re.
4. Check 'Connections' before wiring.
Failure to follow this instruction may result in re.
5. Do not disassemble or modify the unit.
Failure to follow this instruction may result in electric shock or re.
Warning
1. Use the unit within the rated specications.
Failure to follow this instruction may result in re or product damage.
2. Use dry cloth to clean the unit, and do not use water or organic solvent.
Failure to follow this instruction may result in electric shock or re.
3. Do not use the unit in the place where ammable/explosive/corrosive gas, humidity, direct
sunlight, radiant heat, vibration, impact, or salinity may be present.
Failure to follow this instruction may result in re or explosion.
4. Keep metal chip, dust, and wire residue from owing into the unit.
Failure to follow this instruction may result in re or product damage.
5. Since leakage current still ows right after turning off the power or in the output OFF status,
do not touch the load terminal.
Failure to follow this instruction may result in electric shock.
Caution
※
The above specifications are subject to change and some models may be discontinued
without notice.
※
Be sure to follow cautions written in the instruction manual, user manual, and the
technical descriptions (catalog, homepage).

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 changing the mode/parameter during operation may
result in malfunction, set the mode and function after disconnecting load output.
4. Re-supply the power to the unit after the unit is discharged completely.
Failure to follow this instruction may result in malfunction.
5. To ensure the reliability of the product, install the product on the panel or metal surface vertically to the ground.
6. Install the unit in the well ventilated place.
7. 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.
8. Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power.
9. Do not wire to terminals which are not used.
10. Since inter element can be damaged when using with coil load, inductive load, etc., the inrush current must
be under the rated load current.
11. Do not use near the equipment which generates strong magnetic force or high frequency noise.
12. This unit may be used in the following environments.

When the power is supplied, this function is able to
protect the load when it controls load (molybdan,
white gold, infrared lamp) with inrush current or the
width of rising temperature in big (SV is big).
SOFT START set time (T) is the required time that
output reaches to 100%, and it is differentiated by
OUT ADJ set value.
Unlike SOFT START which operates only once at
supplying power, this function protects load from the
inrush current in the RUN mode. When reached to
the target output value, operation stops.
Output high limit/low limit value [H-L/L-L]
This function is to limit output range to protect load.
It compensates the offset between actual input value
and measured input value.
E.g.) When input monitoring value is 5% at 4mA in
DC4-20mA control input, setting INB to -5
calibrates the input monitoring value to 0%.

For models with alarm output, the error message and alarm indicator ash at the same time, and alarm output turns on.
※
When multiple alarms occur at the same time, the highest priority error message will be displayed based on priority.
1) SCR error alarm
Even though output is 0%, if the current of 10% or more of the rated load current ows for over 3 sec
continuously, SCR error alarm occurs and output stops.
2) Overcurrent alarm [OCU/OCT]
This function protects the load from overcurrent.
If the current ows over the overcurrent alarm setting value and setting delay time, overcurrent alarm
occurs and output stops.
3) Heatsink overheat alarm
When the temperature of a heatsink is over 85℃, heatsink overheat alarm occurs and output stops.
4) Overvoltage alarm [OVV/OVT]
This function protects the load from overvoltage.
If the current ows over the overvoltage alarm setting value and setting delay time, overvoltage alarm
occurs and output stops.
5) Heater break alarm [HBV]
Comparing the full load resistance value and the current load resistance value, if the current load
resistivity is maintained under the setting value for over 3 sec continuously , heater break alarm occurs.
Output does not stop and operates normally.
