Function Generator
AC Power Supply
EPO series



Output Voltage and Output Frequency

Equipped for a wide range of output voltages and output frequencies.

Wide range of output voltage and frequency can offer versatile applications such as frequency converter for domestic,voltage change for overseas equipment, and also to testing aircraft and vessel's appliance, etc.

Output Voltage Range Resolution
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.



Plus :

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° units through input phase setting function. Comes in handy when evaluating in rush current on equipment under test.
Key lock function 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.
