EATON has released a compact digital meter for measuring volts, amps, frequency, maximum demand and total harmonic distortion in current and voltage.
The Circutor DM45-CM is design for DIN rail mounting and measures three centimetres wide. It has measuring ranges of 50 to 600Vac, ten to 600Hz, zero to 30A for direct connected units or 5A for indirect units.
It offers an output relay which can be used for an alarm function, with the possibility of setting up maximum or minimum levels, connection and disconnection delays, latching and failsafe options.
The unit also has internal memory which will store the minimum and maximum values of measured electrical parameters so they can be restored after a power failure.
