HIGH POWER DC POWER SUPPLY WITH AUTORANGING OUTPUT

Capable of 3 times the previous voltage and current output within the rated output power

  • Voltage range: 80V to 1500V
  • Current: 30A to 510A
  • Power: 5kW to 15kW
  • Variable internal resistance function

Three times and wider voltage and current within the rated output power 15 kW

PRT series is a DC power supply equipped with a turbo function, enabling an autoranging of voltage/current output three times higher than previous DC power supplies with the same rated output power level. The PRT series allows flexible voltage and current output within its rated power, and you do not have to search for a power supply with a wider rated voltage and current than necessary. Thus, a single PRT unit can be used for much wider user applications.

In addition to the autoranging of output, the PRT series enhanced its general performance of the power supply to achieve overwhelming quality, providing a power factor correction circuit with 0.99 power factor, a color display panel having excellent visibility, and adoption of the speedy and excellent precision rotary encoder.

    More Space Saving for Better Workplace | PRT series | DC power supply Rackmount | Matsusada Precision

    State-of-the-art semiconductor
    In order to minimize the heat generation itself inside the power supply, we adopted the latest device including semiconductor elements of high efficiency via thorough examination. This enables the product to provide a sufficient cooling function to maximize high performance.

    Air-through circuit block technology
    With the improvement of the air-through circuit block, the product has been made smaller, and we also have put more focus on the improvement of block arrangement contributing to excellent space efficiency by extremely reducing the dead space. Consequently, we achieved the significant development of high-density mounting technology. While extra spaces inside the device had been required to release the heat so far, we successfully made the product even smaller to ensure the total amount of height of a mere 133 mm.

Functions

Expandable to 150 kW with Master/Slave Control

Easy expansion of your choice up to 150kW
Within the same series, you can increase the capacity using the shared cable and parallel control cable (LAN cable).
Even if you want to change testing items or targets, you have only to add the necessary amount.

("Master/Slave Control Cable", a Matsusada Precision original set of pre-processed share cable and parallel control cable is available.)
<Example> (1) 10 units in parallel of PRT80V510A in 15 kW → 80 V/5100 A/150 kW (2) 10 units in parallel of PRT1500V30A in 15 kW → 1500 V/300 A/150 kW

  • Expandable to a total of 10 Master and Slave units.
  • In the Master/Slave connection, the values of output voltage/current for the whole unit are shown on the output voltage/current meter of the Master. (However, each Slave unit does not display the individual output values on the output voltage/current meter.)

Note: Make sure to use the same length of all the cables to connect each load and the main unit.

CV/CC Priority Setting Function

CV (constant voltage) priority/CC (constant current) priority mode can be selected and set. As is the case with diodes, a load tends to suddenly change the resistance at certain points. When the device is started in CV mode, the current will be momentarily overshot. In the PRT series, select the CC priority mode to suppress the occurrence of overshoot. The function can reduce the risk of damaging expensive loads such as high-power laser diodes.

* In the CC priority mode, do not by releasing the voltage setting and setting the CC value to the lowest within the range where the CC state can be maintained.

CV/CC Priority Setting Function | PRT series | Rack Mount DC Power Supplies | Matsusada Precision

Internal Resistance Variation Function (in CV mode)

Set the internal resistance to any value to generate a voltage drop when the load current flows.
Batteries, photovoltaic cells, and fuel cells can be simulated.
(The setting range of the internal resistance value is from 0 Ω to the rated voltage/rated current.)

CV mode | PRT series | Rack Mount DC Power Supplies | Matsusada Precision

Preset Memory Function

With the preset memory function, the preset values are automatically saved when the power turns off.
Furthermore, up to three different voltage, current, and power settings are also memorized respectively.

Sink current prevention function

The function is suitable for supplying power to loads with capacities like batteries and capacitors. It reduces the reverse current flowing from the load to the unit in order to prevent a voltage drop on the load as the output is OFF or the set voltage is lowered.

Sink current prevention function | PRT series | Rack Mount DC Power Supplies | Matsusada Precision

Note: Reverse current cannot be controlled and stabilized. In order to protect the power supply unit, connect a dummy resistor or reverse current prevention diode if the load of the reverse voltage is equal to or higher than the rated voltage (inductive loads, regenerative motors, etc.).

Two-mode Lock Function

The locking is selectable from two setting modes: One is "Full LOCK" to lock all front panel operations, and the other is "Normal LOCK" to lock all operations except the ON/OFF switch.
The function is so user-friendly that the "Full LOCK" mode is provided to ensure the prevention of erroneous operation, and the "Normal LOCK" function facilitates the emergency stop while preventing erroneous operation. Emergency stop operation using the POWER ON/OFF switch is possible in either mode.
