General Information

EPM-14 is designed to measure the current of the single phase systems.

Applications of EPM-14

1) It can measure Current in single phase systems.

2) You can observe demand and max. demand value of measured current with

2 different periods, also the calculation time for demand and max. demand value

can be determined from the dE-t (demand time) menu.

3) Current transformer ratio can be programmed,

[1....1000 (for X/5A), 1....5000 (for X/1A)]

4) A password can be arranged from CodE menu in order to prevent

change of the setting by unauthorized person.
