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.
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.
Output control employing our unique hybrid power control technology
User interface designed to take into account how each customer uses the equipment
Energy-saving design to efficiently supply power and improve equipment operability
DP Series, we took into account the basic ways that AC power supplies are used, and focused closely on basic performance, functions and ease-of-use.
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.
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.

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.
System Lineup
Please select required capacity for each required model: single-phase, single-phase 3-wire, three-phase, or multi-phase. A polyphase system can be configured by combining multiple units of the same single-phase model.
