THYRISTOR CONTROLLER | THREE PHASE DMPR3 Series X10747 36kW(50A), 54kW(75A) / 415V 3-Phase Dual Mode Power Controller 0044 (0) 1704-516 501 enquiries@united-automation.com www.united-automation.com CONTACT US: KEY FEATURES: The DMPR3 series offers robust control for inductive and resistive loads, handling up to 54kW at 415V. This fully enclosed thyristor assembly provides versatile operation with user-selectable control modes—phase-angle, burst- firing, or a hybrid mode combining both. This flexibility, combined with frequency tracking from 30-80Hz, makes it ideal for installations with unstable power supplies. Designed for easy installation, the DMPR3 features accessible internal signal and power terminals, along with integrated high-speed fuses and a heatsink for reliable performance. It is suitable for a wide range of heating, ventilation, and industrial applications, including furnaces, ovens, dryers, and air curtains, as well as inductive loads like transformers.  Dual Mode Control: Phase-Angle, Burst Fire, or Hybrid  Frequency Tracking: 30- 80Hz for unstable supply environments  Integrated High-Speed Fuses for enhanced protection  Adjustable Ramp Control: 0 to 30 seconds for smooth power-up  Easy Installation: Accessible internal terminals and multiple cable entry options TECHNICAL SPECIFICATIONS Power / (Current) Ratings 36kW (50A); 54kW (75A) @ a typical supply of 415V RMS nominal Input Voltage 415V RMS +/- 10% Frequency 30 – 80Hz Control Input Options Signal 0–5V/0-10V Manual 5kΩ Potentiometer/4-20mA Load Type/Selectable (SW4) Resistive or Inductive Adjustable Ramp Control from Power Up 0-30 seconds Control Limit or over current trip 0-100mV dc or 0-25V dc Over Current Warning LED2/LED3 pulse alternately Cable Terminations (all internal) Phase Power M6 nut & washer stud terminal.

The wiper should be connected to the terminal labelled "I/P," while the counterclockwise terminal should be connected to 0V. Voltage Control For remote DC signal control, connect the positive input to the terminal labelled "I/P" and the negative input to 0V. The input impedance is 10kΩ for a 0-5V input and 20kΩ for a 0-10V input. Current Control To utilise current control, connect a 4-20mA DC signal between the terminals labelled "4- 20mA" and 0V. This input can also accept a 1-5V DC signal. The input impedance for current control is 240Ω. Phase-Angle Control

  • Option 1: Set the switch labelled SW1 to the "ON" position. This action connects terminal A with the 5V supply.
  • Option 2: For alternative control (see "Soft-Starting"), switch SW1 to the "OFF" position, isolating the inputs and disconnecting terminal A from the 5V supply. Inputs A and C will then require an external supply between 5V and 24V DC. Burst-Firing Control To enable burst-firing control, switch SW1 to the "OFF" position and link terminal B to either the onboard 5V supply or an external 5-24V DC supply. Phase-Angle to Burst-Firing Transition For a seamless transition from phase-angle to burst-firing control, switch SW1 to the "ON" position and link terminals A and B together. The firing circuit will initiate in phase-angle mode and automatically switch to burst-firing mode as the control signal ramps up to the set point. It will remain in burst-firing mode even if the signal drops below the set point and will only restart in phase-angle mode when the unit is turned off or reset. Soft-Start Upon initial power-up, the FC36M’s output is inhibited for 0.5 seconds. The soft-start feature is then automatically enabled, and the firing circuit will gradually ramp up according to the rate set by VR3 (adjustable from 0 to 30 seconds). The ramp time corresponds to full conduction; for example, if the ramp time is set to 30 seconds and the set point is 50%, the controller will reach the set point in 15 seconds.

If the unit is installed in an enclosure or cabinet, adequate ventilation and/or forced air-cooling should be provided. Thermal trips are installed on all controllers, and it is recommended to wire them in line with the signal to disable the controller in case of an over-temperature situation. Load Considerations When ordering, it is crucial to specify the type of load. The DMPR range is engineered with substantial current overload capacity on the power devices, ensuring industrial reliability. The rated currents represent maximum continuous RMS values within the specified temperature guidelines. Special heating loads, such as those involving molybdenum, platinum, or tungsten, exhibit a hot-to-cold resistance ratio of approximately 10:1, resulting in significantly higher current draw when cold. Inductive loads like transformers also experience surge-starting currents, necessitating the correct type of phase-angle firing circuit. Indicate these surge loads when ordering to ensure that appropriately rated units or slow-start options are supplied to meet specific application requirements. Max.
