High power DC Power Supply
with Wide Range Output

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

  • Max Voltage: 80V to 1500V
  • Max Current: 30A to 510A
  • Max 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 a wide range of voltage/current output three times higher than previous DC power supplies with the same rated output power level. The PRT series all 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 wide range 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.

How to compact

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 such a sufficient cooling function to maximize the high performance.
Air-through Circuit Block Technology
Following the structure review of the 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 150kW with Master/Slave Control

Easy expansion of your choice up to 150kW

Within the same series, you can increase the capacity using the share 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 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 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 between 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 momentary overshot. In 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.

CV priority mode Matsusada Precision CV priority mode
CC priority mode Matsusada Precision CC priority mode

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

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.)

Matsusada Precision Internal Resistance Variation Function (in CV mode)

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.

Matsusada Precision Sink current prevention

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.

Password Function New

In this function, to cancel the two-mode lock function, input a 4-digit PIN code. (Enable/Disable is selectable.)

Master/Slave control cable

  • Model Name: PRT-MS  cable

The cable is a combination of share cable with terminals (figure at right) and parallel control cable . The length of each cable from the terminal to the terminal is approximately 1.5 meters. Therefore, when connecting two PRT, the length is about 1.5 meters, and when connecting three PRKT, the length is about 3 meters.
When placing an order, please put a number from 2 to 10 in.
