MIPS 48 DC Mains Measurement Controller

MIPS 48 DC power grid parameter measurement controller is equipment used as part of automated systems to provide simultaneous measurement of current voltage distributed over six independent measurement channels. The mains measurement controller is supplied in a kit consisting of the DC parameter controller itself and current sensors mounted directly on the cable. On the top board of the MIPS -02 DC mains measurement controller, the bipolar voltage required to supply the sensors is formed. DC controller is used as a component of such technological systems as Base station climate control system, remote control of life support systems of country houses, as well as Automated Information and Measuring System of Commercial Energy Metering (AIMSCEM “PUMA”).

Main functional capabilities of the device MIPS-02 “Jcom-iot”:

• monitoring of voltages and currents for six independent channels via RS485 interface;
• voltage measurement directly at the input of one of six voltage measurement channels;
• voltage measurement from the voltage output of the current sensor for one of six current channels of MIPS-02 ;
• use of non-contact current sensors in current measurement channels, provides easy connections and allows to cover a wide range of currents;
• solid-state relay for signaling the occurrence of a programmed event;
• MIPS-02 device can be integrated into the Automated Information and Measuring System of Commercial Energy Metering;
• possibility to configure the device via RS485 interface through the program “Element Manager MIPS-02” locally or remotely.

Device and operating principle:

The device (or meter) is a means of automation of the monitoring process and provides simultaneous measurement of voltage and current values through six measurement channels. Upon requests from external devices (by appropriate commands), the array of measured voltage and current values is transmitted to the user and on the user’s side any transformations (plotting by points, power calculation, etc.) necessary for further analysis can be performed with these arrays. For example, since voltages and currents are measured almost simultaneously, on the user side it is possible to calculate the instantaneous power at the measurement points by simple multiplication of the corresponding voltages and currents. Meters both autonomously and as a part of information-measuring systems can be used to control parameters of electrical installations, in technical diagnostics equipment, for complex automation of power facilities and in other areas of industry where multi-channel measurement and control of constant voltages and currents are required. When polling the meter, the master device can be the Information Acquisition and Transfer Controller (IACAC) “PUMA” or a PC with RS485 converter. Current measurements are made with the help of external (separate) current sensors, which determine the range of measured currents. The voltage corresponding to the measured current must be fed from the output of the sensors to the measuring input of the current channel of the device. The measurement results of all parameters are output digitally on request via RS485 interface after receiving a special Get_Data command from the master. Structurally, the current sensors are based on current transformers. The current sensors are powered by a bipolar voltage source, which is a module functionally and electrically independent from the meter, structurally located on the upper board of the device in a single housing with the meter. The power supply corresponds to the upper row of connectors of the device. The meter is structurally located on the lower board of the device and corresponds to the lower row of connectors. When using other types of current sensors that do not require external power supply, the connectors of the upper board are not used and can remain unconnected.
