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.

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

Program as image
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 release the voltage setting and set the CC value to the lowest within the range where the CC state can be maintained.
Variable Internal Resistance 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.)
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.
Remote Control Software (Additional Products): DigiCon series
DigiCon is an application package that remotely controls Matsusada Precision's DC power supplies connected via LAN.
The software can control multiple power supplies simultaneously or individually.

Link with digital multimeters, data loggers, and thermostatic chambers is possible.
Program transitions can be made in response to external conditions by linking with measuring instruments such as digital multimeters and data loggers, as well as thermostatic chambers.
This advanced function allows the program to transition to the next step when the end condition of the instrument is met without waiting for a set time, or to safely terminate the program if a problem occurs during operation.
Easy operation enables speedy construction of Automatic Test Equipment (ATE)
Graphical user interface, including graphical display of set values, allows easy operation.
Automatic Test Equipment (ATE) and inspection systems can be built without programming knowledge.
It can be used in many fields and applications, such as long-term reliability testing of electronic equipment and devices in the automotive, home appliance, and medical fields.
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.
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
