High Power DC Turbo Power Supply
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.

Capable of covering a wide output range with parallel connections of up to 10 units in total.
Note: Always use cables with uniform thickness and length over the full length for output cables connected to the load from these devices.
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.
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.
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 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.
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.
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.
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 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.)
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.).
Isolation control is performed by optical communication. As complete isolation is performed by means of optical fiber, this enables advance prevention of erroneous operation comprising transient phenomena resulting from surges, inductive lightning, external noise, etc.
Please purchase a control-side optical communications adapter separately.
