The Autonics DPU34B-200R is a 3-phase digital power controller that offers optimal and stable power control with minimal noise interference. The unit has a 440VAC power supply and has a size of 70 to 200A. Moreover, the rated load current is 200A and the unit comes with an RS485 communication option.

Convenient Installation with Remote Display

Users can remotely monitor and control the units by installing the remote display unit in separate control panels.

Various Control Methods

Zero cross ON/OFF control, standard control, feedback control, and zero cross cycle control (fixed/variable cycle) are available for stable load control.

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%

Various Functions Available

Various user friendly functions are available including soft start, slow up/slow down, input/output slope correction, multi-SP (setting point), full load auto recognition, and more.

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.

Various Alarm Features

Various alarms are available for safe operation, including overcurrent alarm, overvoltage alarm, fuse disconnection alarm, heatsink overheat alarm, heater disconnection alarm and more.

Simple Fuse Replacement

Open type case allows users to easily replace fuse in the power controllers.

Applications: Semiconductor/Display Industry

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

Machine Tools Industry

Single-phase power controllers used in reflow ovens to accurately control temperature using feedback control.
