MTE — Measuring digital converter of electrical parameters of one connection type MTE 1XXX
MTE 1ХХХ is an autonomous unit and provides analog signals from
output circuits of current and voltage measuring transformers of one connection, their conversion to a digital code, measurement of the network frequency, calculation of additional parameters (P, Q, S, cosφ) and data transmission via a digital serial channel (RS485) to the controller-concentrator (KPL-32 cabinets of the Moscow State University). The exchange protocol is Modbus (RTU).
МТЕ1ХХХ is produced in various modifications in terms of quantity and type
input signals:
— MTE1420 — multifunctional (3 currents and 3 voltages);
— MTE1130 — 3 voltages;
— MTE1110 — 1 voltage;
— MTE1230 — 3 currents;
— MTE1210 — 1 current.
As an additional option, the MTE 1XXX can be supplied with a panel one- or three-line digital device (SHPO-1, SHPO-3) for visual display of parameters
physical units of measurement. It is connected to the converter by the second
digital serial channel (RS-485), which allows you to place it remotely from
places of installation of the converter.
Both digital channels have galvanic isolation from the main nodes of MTE 1XXX.
Supply voltage ~/= 220 V. The power consumed is no more than 2.5 VA (W).
Degree of mechanical protection IR20. Overall dimensions 100 x 75 x 105 mm, weight no more than 0.75 kg.
Operating temperature range from minus 40 to 60 °C
