The EPO series is a line of epoch-making power supplies, using new method of power amplifier unit.
They provide high efficiency (approx. 76%) unimaginable with previous products, while being even more light weight and compact. These epoch-making AC/DC power supplies feature even further improvements to standard features such as the flexibility, high output stability , and powerful supplies of electric power that NF power supplies are known for. |

System upgrading, Phase mode selectable
|
The EPO series is divided into 3 systems according to phase and respond to a variety of uses.
Boosting Rated Power and Phase Mode Selectable Output (single phase/three phase/single phase three wire) with the EPO2000X .
The Single phase 2kVA is our basic unit. It can be used as a master or a booster. You can link up to three units of the same model and the EPO2000X allows phase mode selectable output, making it easy to build a 4kVA single phase/single phase three wire system with two units or a 6kVA single phase/three phase system with three units. The EPO2000X is a flexible unit that can accommodate the refabrication common on production lines.
|
|
Single Phase Systems
This line-up includes 2kVA-12kVA systems. The 4kVA unit comes in M-sized (787.5mm tall) and 8kVA-12kVA units come in L-sized (1,365.5mm tall), all in slim cabinet styles.
|
Phase Mode Selectable Systems
This line-up includes 6kVA-36kVA systems. These products can be used in every mode; single phase, three phase, and single phase three wire. They come loaded with functions not to missed by those who want to use them in various ways as a single power supply. Each system is housed in a sleek, well-organized cabinet.

|
High efficiency with low input current |
|
|
|
76% power efficiency, reducing running costs
|
| Achieves 76% power efficiency. Plus, we've reduced input current to a mere 14A (at 200V) and even further reduced harmonics current. Suppresses futile power consumption and heat generation, and contributes to business cost reductions. |
|
|
Maximum output peak current |
|
|
|
Maximum peak current up to four times of the rated value
|
| The capacitor input type rectifier loads used by many electronic devices tend to consume large current in pulses, as shown in the illustration below. For this reason, you need an AC power supply capable of supplying large current instantaneously. The EPO series can put out up to four times the rated value (rms) maximum peak current. |
|
|
Stabilization and improvement of waveform |
|
|
| Instantaneous voltage stop |
Input voltage waveform distortion |
 |
 |
| 0V, 1 wavelength (20rms),rated load |
distortion rate 3.6%, rated load |
|
stable output and low distortion of waveform
|
| The EPO series improves a voltage of various power line environment. And also increases withstanding level of a discontinuance, a distortion and an instantaneous voltage drop of line voltage. |
|
|
In Rush Current |
|
|
| Current waveform at the start-up of motors |
 |
|
to increase output capacity at the start-up of motors
|
| For each unit's 20 Arms maximum output current, the unit can supply up to 2.8 times 57 Arms (80 Apeak) of in rush current. The EPO series addresses the need for power supplies with large rated output current for handling large loads of in rush current, such as during motor start-up. With the EPO series, you no longer need to put extra money in the budget just for system startups (to increase output capacity). |

| 100V range : 0V to 150.0V |
0.1V |
| 200V range : 0V to 300.0V |
0.1V |
| In three phase and single phase three wire modes, settings can be made by phase voltage or line voltage(resolution 0.2V). |
| Output Frequency Range |
Resolution |
| 5.0Hz to 550.0Hz |
0.1V |
|
|
|
DC Output |
|
|
Appropriate for DC/DC converter testing
| Permits 0V to +424V output voltage(0.1V resolution), +9A maximum current (at 2kVA), and 900VA maximum power (at 2kVA) DC output. A single unit can be used as an AC power supply or as a DC power supply. |
|
|
Output current during low power factor load |
|
|
High stability mode secures the performance of L, C load
| Load power factor is guaranteed at 0-1 (lead, delay). Provides 100% rated current even during power factor 0, so there's no problem running fluorescent lights, switching regulator, and so forth. |
|
|
Measurement Function |
|
|
Free from external measuring instruments
| AC |
Voltage(rms, peak), Current(rms, peak), Effective power, Voltampere, Power factor, Peak current holding *Phase voltage an line voltage can be displayed in three phase mode and single phase three wire mode. |
| DC |
Voltage, Current, Electrical power, peak curent holding |
|
|
|
Failure Diagnosis Function |
|
|
| These power supplies conduct their own failure diagnoses checks during power start-up. If a problem is detected during start-up, a warning message is displayed and the flow of electricity to main electrical parts is cut off to prevent the problem from spreading. |
|
|
Protection function |
|
|
| Built-in 7 system protection function safeguards load and power supply from such problems as output short circuits, over current ambient temperature rises, and line voltage drops. Momentarily limits output in the case of temporary over current, etc. Automatically recover to normal output after the problem has been corrected. |
| Check items |
Output current, Output voltage, Input voltage abnormality of power amplifier,Over-current of power amplifier, Overheat of internal heat sink,Operation stop of DC power supply, Operation stop of power amplifier |
|
|
|
Memory function |
|
|
| This function can memorize (store) and easily recall 10 panels of setting status such as output voltage, frequency, etc. And also it can recall quickly frequent used setting through preset keys. |
|
|
External Ten-Key Input |
|
|
Easy and convenient for setting change and inspection work
 |
By connecting the ten-key pad to the front panel, you can input numeric values through a ten-key pad as well as by the dial. It can also be used as a "Recall panel" for recalling settings programmed in memory, making it convenient for inspection operations on production lines and so forth. *Ten-Key pad optional. |
|
|

|
| Line synchronization output |
Provides AC output which is synchronized power supply line frequency by line synchronization output function |
| Limiter function |
Maximum output voltages as well as maximum and minimum frequencies can be preset with the limiter function. |
| Start phase setting function |
Start phase at Output ON can be set to 90˘X units through input phase setting function. Comes in handy when evaluating in rush current on equipment under test. |

Equipped with key lock functions which allow you to nullify panel key operation |
| Buzzer |
Warning buzzer notifies you of erroneous operation and overload protection status. |
|
|
