AC Power Source
Programmable AC Power Source
DP series

standard to powerfully support various tests and measurements.

The DP Series has performance and functions required of a power supply
while meeting the unique needs of each customer.
Strong and smart — this is an AC power source for the future.

dp series

NF has knowledge and skill about AC power source and our DP Series incorporates new ideas while pursuing the high-quality, stable supply of power that is the fundamental role of any AC power source.

ball New Line-up

DP160LS: Single-phase model (16 kVA)

DP240LM: Multi-phase model (24 kVA)

DP360LM: Multi-phase model (36 kVA)

* Line-up *

You can select the optimal power supply from a broad range of options, from single-phase 1.5 kVA to a maximum of three-phase 144 kVA.

DP series Line up (Approx.458KB)


The lineup includes single-phase, single-phase 3-wire, three-phase and multi-phase ( single-phase, single-phase 3-wire, or three-phase selectable) models.
A multi-phase system (single-phase 3-wire/three-phase) can be configured by connecting multiple units of the same single-phase model.

* Power input depends on the model. See the spec sheet for details.

* Output Characteristics *

The DP series achieves stable output with low distortion, and operates stably with high-capacity capacitor loads. With a variety of output modes and a wide output range.
AC/DC modes: AC, ACDC, DC
Output voltage/frequency
    100 V range 200 V range Resolution
AC Output voltage 0 V to 160V 0 V to 320V 0.1 V
AC: 40Hz to 550Hz 
ACDC: 1Hz to 550Hz
DC Output voltage -227 V to +227V -454 V to +454 V 0.1 V
Output voltage fluctuation: within ±0.15 V (75 V to150 V)/within ±0.30 V (150 V to 300 V)
 (DC, 45 Hz to 65 Hz if output current is varied from 0% to 100% of maximum current)
Maximum peak current: four times the maximum current (RMS value) (corresponds to a capacitor input rectified load with a crest factor of 4)

Waveform distortion rate: 0.5% max.


* Measurement Functions *

In addition to voltage, current and power, the DP series optionally supports measurement of load power factor, crest factor, and up to 40th-order harmonic current. In addition, the series supports measures to control CO2 by displaying CO2 emissions during operation.

Measurement Items
Voltage: RMS value, average DC value, peak value  
Load power factor
Current: RMS value, average DC value, peak value, peak hold value  
Crest factor
Power: active power, apparent power, reactive power  
Sync frequency
Harmonic current: up to 40th order  
CO2 emissions

* Simple Operation *

Panel operation is a breeze using the large, easy-to-read display.
The design stresses improved ease-of-use and work efficiency for users, with features such as a function for selecting three decided measurement items and displaying them enlarged, and remote operation using a remote controller.
