The EM-MPO/350 is a DIN rail mounted 3 phase multiparameter electricity meter with an (8 digit) LCD display and The EM-MPO/400 is a panel mounting 3 phase multi-parameter electricity meter with a backlit 3 line display. The /350 and the /400 require 5 A current transformers, whereas the /350e and /400e use the CSENSOR range of split core current sensors. Voltage transformers may be used for medium to extra high voltage. The required transformer ratio is programmable from the panel. Used in conjunction with the EMIC (Ethernet Metering Interface Controller) or a Trend IQ3/XNC MODBUS driver, logged data can be accessed directly over the Trend network.
