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
The PRT series of products are DC power supplies equipped with a turbo function, enabling output voltage and current across a range three times wider than previous DC power supplies with approximately the same rated output power.
Because each model can flexibly output voltage and current within the range of its rated output power, a single one of these units can be used for a wide range of applications without the need to introduce a power supply while allowing a margin for output voltage and current.
They not only enable wide output, but also take the baseline performance of a DC power supply to an even higher level, including the adoption of power factor improvement circuits that achieve a high power factor of 0.99, a large liquid crystal display with excellent visibility, and a rotary encoder capable of speedy and accurate setting.

Functions
Output Range Graphs
Turbo function enables a wide range of voltage and current output compared to previous DC power supplies. The PRT series outputs voltage/current with in the rated output power.





Main Functions
Supports Expansion 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.
- During MASTER/SLAVE connections, values of output voltage/current for the overall unit are displayed on the output voltage/current meter of the MASTER. (Individual output values are not displayed on the output voltage/current meter of each SLAVE.)
Note: Always use cables with uniform thickness and length over the full length for output cables connected to the load from these devices.
[Connection Diagram]

Dedicated cable for master/slave connection can be also prepared. This is the set of a parallel control cable and a cable with attached shared terminal. go to Master/slave control cable
Preset Memory Function
Equipped with memory preset function. Maintains preset values automatically when powered off. A maximum of up to three other voltage settings, current settings, power settings, and CV/CC priority settings can be saved.
Sequence Function
Equipped with programmable sequence function such as step time, step amplitude, ramp, CV/CC mode, sequence end setting, step jump, and jump count.
This allows free waveforms to be generated, enabling use for a variety of applications including testing and 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

Because dedicated software for setting with PC is also attached, it is possible to use properly according to usage.

CV/CC Priority Setting Function
CV (constant voltage) priority/CC (constant current) priority modes can be selected and set. At loads where resistance suddenly changes at certain points, such as diodes, current will overshoot if started in CV mode.
In the PRT series, occurrence of overshoot can be suppressed by selecting CC priority mode. The risk of damaging expensive loads such as high-power laser diodes can be reduced.
Also equipped with protection functions and front panel lock function as standard.

* Overshoot is less likely to occur if the value is set to the lowest in the range that the CC state can keep, without releasing the voltage setting even in CC priority mode.
Sequence Setting Input & Output/Operation Log Output via Front USB Terminal
Sequence files can easily be read and logged by inserting USB memory into the front panel USB port. Sequence files can be created easily with a PC application.

It is a dedicated software for viewing action logs.
- Elapsed time
- CC mode/CV mode
- Output value (voltage, current, power)
- Status
- Error
These action logs can be displayed.
Two-mode Lock Function
Can be set by choosing from two modes: “Full LOCK” to lock all front panel operation and “Normal LOCK” to lock everything except the OUTPUT ON/OFF switch.
This is a convenient function that takes into consideration safety from the customer's perspective, with “Full LOCK” mode for reliably preventing erroneous operation and “Normal LOCK” for facilitating emergency stop while preventing erroneous operation.
Emergency stop via the POWER ON/OFF switch is possible in either mode.
Full LOCK

Except for LOCK release, all switches, the touch panel and encoder are locked. Effective for preventing erroneous stop during remote control and completely erroneous operation.
Normal LOCK

Switches other than OUTPUT ON/OFF, the touch panel, and encoder are locked. Effective for preventing erroneous changes of output values during local control and to facilitate emergency stops.
Internal Resistance Variation Function (during CV mode)
Internal resistance is set to an arbitrary value, and a voltage drop is caused by the load current.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.)

Sink Current/Sink Current Prevention Function
The power supplies are equipped with a sink current function, making it possible to reduce the voltage quickly when turning off the output or when decreasing the voltage from a high setting value, thereby improving the safety of operation.
In addition, quick connections can be made after the output is turned OFF, and workpieces can be changed when conducting a series of burn-in tests.
Conversely, when supplying power to loads with capacities such as batteries and capacitors, the sink current prevention function can be used to reduce reverse current flowing from the load side to the power supply side and prevent a drop in load voltage when the output is off or when decreasing the set voltage.
* The sink current prevention function is not available in models that have an output of 850 V or higher.


Note: Reverse current cannot be controlled and stabilized. Connect a dummy resistor or reverse current prevention diode when load of the reverse voltage is equal to or higher than the rated voltage (inductive loads, regenerative motors, etc.).
Status output

Common is floating in open collector output of common.
Withstand voltage; 30 Vdc
Sink current; 5 mA or less
