Constant Voltage Feedback
Control Mode

Maintains constant output voltage relative to the control input when there is a change in power supply or load resistance of loads with low temperature coefficient of electrical resistance (iron, chrome, nichrome, etc.)

Constant Current Feedback
Control Mode

Maintains constant output current relative to the control input when there is a change in power supply or load resistance of loads with high changes (6 to 12 times normal temperature) in temperature coefficient of electrical resistance (platinum, molybdenum, tungsten, etc.)

Constant Current Power
Control Mode

Maintains constant power supply relative to the control input when there is a change in power supply or load resistance. Ideal for large heaters with high changes in resistance due to overheating such as silicon carbide (SiC).

Zero Cross Cycle Control (Fixed Cycle)

The load power repeats ON/OFF control during a fixed cycle (60 cycles) in relation to the control input signal.

Example) Fixed cycle (60 cycles) control - control output at 40%

Zero Cross Cycle Control (Variable Cycle)

Minimal number of cycles are used as AC sine wave repeats ON/OFF control in relation to the control input signal

Example) Variable cycle control - control output at 40%

SLOW UP / SLOW DOWN

Used to protect the load from inrush current during RUN mode.

Output High Limit/Low Limit

Used to protect the load by limiting output range.

Output Slope Setting

Used to set the output ratio between 0.00 and 1.00 in relation to control input.

Multi-Setting Point

Set up to 6 setting points, and the output can be controlled in relation to 3 digital inputs.

Semiconductor/Display Industry

Power controllers are used in semiconductor and display heat regulators which require precise temperature control.

Machine Tools Industry

DPU series power controllers are used in reflow ovens to accurately control the temperature using feedback control.
