A. Product Overview

The Autonics DPU14A-070A Single Phase 70A Digital Power Controller is designed to regulate electrical power supplied to compatible single phase industrial loads.

Instead of simply switching a heater fully ON or OFF, the controller can regulate the amount of electrical power delivered to the load according to an analog signal, pulse signal, contact input, manual adjustment or communication command.

The DPU14A-070A supports both non-feedback and feedback based power control, making it suitable for applications where stable voltage, current or power delivery is important.

B. Working Principle

The Autonics DPU14A-070A controls the electrical power supplied to a single phase load through thyristor based switching.

A temperature controller, PLC or other automation device sends a control signal to the DPU14A-070A.

For example, the controller can receive a 4 to 20 mA signal representing the required output power.

When the control demand is low, the DPU14A-070A supplies less electrical power to the load.

As the control demand increases, the controller increases the amount of power delivered.

The exact way power is regulated depends on the selected control method.

Phase Control

Phase control regulates the portion of each AC waveform supplied to the load.

It provides smooth power adjustment and can be used with compatible resistive and inductive loads.

The phase control output range is 0 to 98 percent.

Fixed Cycle Control

Fixed cycle control regulates power by switching complete AC cycles according to the required output percentage.

It is intended for compatible resistive loads.

Static Voltage Feedback

The controller monitors voltage and adjusts its output to maintain more stable voltage delivery.

Static Current Feedback

The controller regulates output according to load current.

Static Power Feedback

The controller regulates output according to electrical power supplied to the load.

These feedback functions are useful when supply or load conditions change during operation.
