The advantages are easy to see. With respect to a traditional transducer, the SPT-DIN offers:

Measurement in true RMS, selection and optimisation of field measurements with complete freedom on the part of the operator, soft touch keyboard and integrated display. The possibility of modifying the configuration of the transducer and both the type and calibration of the main measurements, (prior to SPT-DIN, the choice of power transducer depended strictly on the size of the measurements and the characteristics of the electrical line), and possible successful modification was rarely feasible.

Local control of a large selection by means of a set point alarm with static output, eliminating the necessity for an additional instrument; the static output can be activated, alternatively, in remote mode by means of an RS485 interface.

The CVT-DIN, is a new series of compact and economical electrical transducers for the measurement of voltage, current and frequency. Two analogue outputs (one of these can be substituted by 3 digital inputs) independently configurable for the simultaneous transmission of 2 chosen values, and a pulse output for energy counting thereby obtaining a saving on cost, cabling and space.

RS485 interface (with the possibility of interfacing with other transducers to construct a network) means that it is possible to configure in remote mode, to transfer all the electrical measurements of the system, to control the state of the three logic inputs and the remote control of the alarm outputs.

In a module just 71.5mm wide suitable for DIN rail mounting, this family offers three basic types for measuring AC voltage and current; DC voltage and current and frequency.

For all models it will be possible to modify, without the need for further alteration, the calibration of the range from 50% to 130% of the nominal input values, by using a multimeter set to the resistance range.

Common to both the SPT and CVT DIN series are the complete galvanic separation of inputs, outputs and power supplies; the possibility of supply on AC or DC (the latter requires a small external converter) and naturally, the assurance of all technical norms and safety in current use.
