PRT series

High Power DC Turbo Power Supply

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

  • Max Voltage: 80V to 1500V
  • Max Current: 33A to 510A
  • Max Power: 5kW to 15kW
  • Variable internal resistance function

Achieves a wide range of voltage/current output that is three times higher than previous DC power supplies within the range of 15 kW rated output power

PRT series is 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 power supply with wider rated voltage and current than necessary. Thus, 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 power factor correction circuit with 0.99 power factor, color display panel having excellent visibility, and adoption of speedy and excellent precision rotary encoder.

Functions

Expandable to 150kW with Master/Slave Control

Capable of covering a wide output range with parallel connections of up to 10 units in total.

  • Expandable to a total of 10 MASTER and SLAVE units combined.
  • 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.

Master/Slave control cable for PRT series is available as an optional accessory. Go to Master/slave control cable.

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.

Sequence Function

The sequence function allows programming of parameters such as step time, step amplitude, ramp, CV/CC mode, sequence end setting, step jump, and jump count by simply operating on the front panel.
This option enables to generate optional waveforms, and you can use a great variety of applications including testing evaluation, and verification.

  • Step setting time 0.0 to 3,600 s
  • For one program, a maximum of up to 1,024 steps can be configured and stored
  • CV/CC mode can be set for each program
  • Repetition frequency: infinite, 1 to 999
Sequence Function

The product is also provided with the dedicated software to allow a series of configuration using PC.
Thus, you can use the product with different applications depending on the specification.

CV/CC Priority Setting Function

CV (constant voltage) priority/CC (constant current) priority modes 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.
Using the PBR series, the occurrence of overshoot can be suppressed by selecting CC priority mode.
The function can reduce the risk of damaging expensive loads such as high-power laser diodes.

CV priority mode CV priority mode
CC priority mode

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.

Sequence Setting Input / Output and Operation Log Output via Front USB Terminal

With this function, you can readily perform not only reading sequence setting but also collecting operating logs which are arbitrarily created by the user.

Operating log Image
Operating log Image

The attached software can read the log file output from the main unit and shows the data in a graph.
The information on operating log is shown on display as of operation time, CC/CV mode, output value (of voltage, current or power), status, and error information, etc.

Two-mode Lock Function

The locking is selectable from two setting modes: one is "Full LOCK" to lock all front panel operation, 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.

Emergency stop operation using the POWER ON/OFF switch is available in either mode.

Full LOCK

Full LOCK

All switches including the touch panel and encoder are locked except LOCK release. It is further effective to prevent the erroneous stop during the remote control and to completely avoid erroneous operation.

Normal LOCK

Normal LOCK

Switches the touch panel, and encoder are locked other than ON/OFF. It is further effective to prevent the erroneous changes of output values during the local control and to facilitate emergency stops.

Internal Resistance Variation Function (during 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.)

Internal Resistance Variation Function (during CV mode)

Sink Current Suppression

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

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.).

Status output

status output

With the turbo function, wide range of voltage and current output compared to conventional DC power supplies.
