Rack Mount DC Power Supplies PRT series

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 Precision 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.

Application Operations with Front USB Port

No data logger or no always connected a computer required

Shortening time of wiring and preparation, Suited for cycle tests in areas where computers are prohibited.

Features:Built-in data logging

Data logging captures the output data at the fastest interval of 0.1 seconds by inserting the USB memory stick. Also, with the dedicated software MLV, the log data is available in CSV format to output.

Use in places where you cannot always connect a computer

With the dedicated software MSS, you can save the sequence program data to the USB memory and load it from the front USB port. Thus, the program operation is available by the power supply only.

Functions with Front USB Port and Standard Attached Software

(1) Sequence program function: MSS (Matsusada Sequence Software)

Easy to use for beginners

MSS allows you to create sequence program data using the main unit or a computer with the dedicated software (MSS).
The software makes it easier and more convenient to create sequence program data. The created sequence program data can be saved to USB memory, and up to 1,024 steps of the sequence program can be loaded.

(2) Operation log display: MLV (Matsusada Log Viewer) Operation log

Instant graphing of operation logs

Operation log display function: MLV, the dedicated software can read and graph the operation log.
Logging to USB memory is available not only during the sequence operation as described in (1) above but also during the local/external control.

Easy editing of operation logs

MLV can select items you need and save them in CSV format, so you can also edit the data in spreadsheet software with no problem.

Sequence Programming Function

The sequence programming function allows the programming of parameters such as step time, step amplitude, ramp, CV/CC mode, sequence program end-setting, step jump, and jump count by simply operating on the front panel. This option enables you to generate customized original 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 1,024 steps can be configured and saved.
• CV/CC mode can be set for each program.
• Repetition frequency: infinity, or 1 to 999 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 by releasing the voltage setting and setting 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.)

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.

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 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.

Password Function　New

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

Secure Analog Remote Control

The external analog remote control of voltage/current/power is isolated from the output of the power supply as standard.
When controlling/monitoring multiple power supplies, you can use the product more securely as the external analog remote control has a chassis (ground) potential.

External Analog Control

External output ON/OFF

The output can be turned ON/OFF by the external relay or TTL signal. The logic of the signal can be selected by 5 V input.

Remote sensing

It ensures the prevention of stability deterioration caused by the voltage drop (VO-VL) by the resistance (R) of the output wire and the contact resistance (up to 0.5 V).

Remote/Local mode setting

Up to three modes selected from output voltage control, output current control, output power control, resistance, overvoltage protection, overcurrent protection, and overpowe can be switched by relay or TTl signal.

Status output

Flexible error detection function !

Output monitor

(Voltage, Current)

Output control

(Voltage, Current, Power, Overvoltage protection, Overcurrent protection, Overpower protection)

Select only the functions you need! Prepare the lowest command voltage!
Up to three settings are selectable in voltage, current, power, OVP, OCP, and OPP.

Residual Voltage Detection LED

Use for checking residual voltage

The LED on the rear panel blinks when there is voltage remaining on the DC output terminal in output or at output off. it is useful for reference to check if the voltage remains. Be sure to check the voltage before the operation of the unit.

Constant Power Control Function (CP mode)

In addition to constant voltage control (CV mode) and constant current control (CC mode), constant power control (CP mode) is provided.

With CP mode, a constant power supply is provided depending on loads, such as resistors (heaters) whose resistance changes with temperature. It is available without monitoring voltage/current or attaching external control devices (temperature regulators).

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 PRKTs, the length is about 3 meters.
When placing an order, please put a number from 2 to 10 in.
If two units of the PRT series are to be connected as master/slave, please enter 2, and if ten PRT are to be connected at master/slave control, please enter 10.
