ES-1954 Rev.6

MODEL

Power Transducer Series L-UNIT

LSMT2

Functions & Features

• Converting all major factors required for power

management into DC outputs • Compact design •

10 analog outputs and 1 Wh pulse output or Modbus

output • Saving wiring space • DIN rail mounting

• Free selection of measuring items, assigned to any

output channel • Transducer input range is

selectable with Watt, Var, Power Factor or Fre-

quency • Linear output for bidirectional current for

Var and Power Factor • Output characteristics can

be changed according to Lag/Lead for Var and Power

Factor

Typical Applications

• Monitoring panels

ORDERING INFORMATION

See later pages of this data sheet for detailed infor-

mation about availability of the functions for each in-

put configuration.

The unit is configured at the factory according to the

user's specifications, however, measuring items can be

freely selected and assigned to up to 10 output chan-

which require specific hardware to be ordered.

The measuring items are listed below:

A = Line current

V = Line voltage

W = Watt, active power var = var, reactive power

PF = Power factor

Hz = Frequency
