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.

DP Series Single-phase Model
3 kVA / 4.5 kVA / 6 kVA / 7.5 kVA / 9 kVA / 10.5 kVA / 12 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 36 kVA.
ball
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.
ball
A multi-phase system (single-phase 3-wire/three-phase) can be configured by connecting multiple units of the same single-phase model.

* 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.
 
ball
AC/DC modes: AC, AC + DC, DC
ball
Output voltage/frequency
 
    100 V range 200 V range Resolution
AC Output voltage 0 V to 155V 0 V to 310V 0.1 V
Frequency
AC: 40Hz to 550Hz 
AC+DC: 1Hz to 550Hz
0.01Hz
DC Output voltage -220 V to +220V -440 V to +440V 0.1 V
 
ball
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)
ball
Maximum peak current: four times the maximum current (RMS value) (corresponds to a capacitor input rectified load with a crest factor of 4)
ball

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
ball
Voltage: RMS value, average DC value, peak value  
ball
Load power factor
ball
Current: RMS value, average DC value, peak value, peak hold value  
ball
