The P4KF-80 Series, a masterpiece of compact DC power supplies that has achieved further evolution

Matsusada Precision's P4KF-80 series benchtop programmable DC power supplies are a new generation of DC power supplies that have evolved from the previous R4K-80 series. With a width of only 35 mm, it offers both improved rise time and reduced ripple noise. Furthermore, the use of safety terminals and the built-in LAN, USB port, and analog remote control terminal have improved usability and safety.

Four models ranging from 16V/10A (80W) to 320V/0.5A (80W) support a wide DC output range. Convenient auto-range and sequence functions, as well as the quietness provided by the natural convection cooling system, make it ideal for R&D environments. Compact yet high-performance, it can be used for a wide range of applications, including various tests and R&D, such as burn-in of ECUs and Printed circuit boards, LED luminance and IV measurements, and so on.

Features

  • 4-digit meter with visibility
  • Equipped with high-resolution D/A and A/D converters
    A rotary encoder with a click feeling makes it easy to set fine values.
  • LAN and USB ports as standard model
    Easy data collection and automatic measurement.
  • Flexible pulse and ramp functions
    Even without a computer for control, various test patterns can be set using only the power supply itself.
  • Easy-to-understand setting method of voltage and current
    A rotary encoder with a push-button allows easy change of the digits for output voltage and output current settings. Therefore, it is possible to quickly set both detailed output values and large value changes.

Convenient variable range function

Functions

Multi-set memories

Up to three voltage and current values can be stored in addition to the normal presets. Therefore, there is no need to make fine adjustments each time the setting value is changed,which is useful for experiments that repeatedly take data or for product inspection processes.

Backflow current prevention

Prevents reverse current from the load side to the power supply. When a capacitive load is connected to the power supply, it prevents the charge of the capacitive load from flowing back to the power supply side. This function is useful for those who wish to conduct tests while batteries and capacitors remain charged.

The reverse current cannot be controlled and stabilized. For loads where the reverse voltage exceeds the rated voltage (inductive loads, regenerative motors, etc.), connect a dummy resistor or reverse current protection diode to protect the power supply.
Backflow current prevention | P4KF-80 series | DC power supply Benchtop | Matsusada Precision

2-mode lock

Two modes can be set: "Full LOCK" to lock all front panel operations, and "Normal LOCK" to lock only output ON/OFF remaining. Set to "Full LOCK" mode if you want to prevent accidental operation without fail, or set to "Normal LOCK" mode if you want to prevent accidental operation but stop output locally.

* Emergency stop is possible in either mode with the power switch.

Analog remote control (The following master-slave functions are not available)

Voltage and Current Control

Output voltage and output current can be setby a remote control voltage (Vcon: 0 to 10Vdc, Icon: 0 to 10Vdc) and variable resistor.

* -S is common, so external control voltage should be input with respect to -S.Failure to do so may cause malfunction.

Master-slave Control (available only when -LGmb or -LGob option is selected)

This function allows the master unit to collectively control the setting values of the connected power supplies.

*Setting values for each power supply can also be set individually (slave local mode).
*When loads are connected in parallel, the outputs from the master and slave units are not equal.
*The -LGob option is recommended if the device is expected to be used in a noisy environment.
If you wish to use the master-slave function by connecting different models, please contact your sales representative.

Delay trigger (-LGmb, -LGob option selected only, multiple units possible)

The delay trigger function can delay start/stop output from the OUTPUT ON/OFF timing.

*Setting values for each power supply can also be set individually (slave local mode).
It works with the P4K-36 series, P4K-80 series, PK-80 series, PK series, TB series, PKT series, PRKJ / PRK series, and PVCEJ / PVCE series.
Detailed individual datasheets are available for each product, so please contact our sales representatives.

Dual tracking and multiple outputs (available only when -LGmb or -LGob option is selected)

Dual tracking control is possible by connecting the power supplies as positive and negative outputs at the time of master-slave operation to control both positive and negative outputs at the same time.
In addition, the slave local mode, in which each power supply is set individually, and dual tracking operation can be combined to create a multi-output configuration.
