 Panel Measuring and Registering Instruments These devices are ideal for application where monitoring and recording of voltages, currents, power factors, frequency, powers, harmonic distortion of voltage and current, energies etc in three-phase LV, HV, VHV grids are required. It can also measure and record temperature. All measured values are stored in the instrument and can be later downloaded for processing using a remote communication line. SMY device has a bright LCD display and features meny userfriendly wiews on the recorded data. SMZ unit has a LED display for rough environments and embedded electronic electricity meter for more precise energy monitoring.
Characteristics - True root-mean-square values of voltage and current (TRMS)
- Both true power factor (PF) and power factor of fundamental harmonics (cos fi)
- Total Harmonic Distortion and harmonics of voltage and current up to the 25th order
- Viewing actual values on the display and record into the memory of up to 1MB capacity
- Two relays with programmable function
- Local RS-232 or remote RS-485/CAN communication link, MODBUS communication protocol
SMZ: - High contrast LED display with large digits
- Built-in three tariff electricity meter of active (separate import/export) and reactive (separate inductive/capacitive) power
- Two analog outputs 0/4-20 mA with programmable function ("A"-model only)
Instrument Configurations and Options
Related DocumentsBasic Features These instruments are suitable for monitoring and recording voltages, currents, power factors, powers, electric energy, TDH, harmonic components and temperatures in low-, high-, possibly very-high-voltage three-phase mains.
Up to three voltage inputs of nominal value up to 440 V AC, three fully isolated 1-ampere / 5-ampere AC current inputs (from measuring transformer outputs) and one resistor thermometer with a 4-20 mA output can be connected. Two relay outputs with programmable function can be used. Built-in real time counter can be synchronized through appropriate synchronization input. Two pulse outputs can be programmed for active or reactive power transmission.
Data measured and recorded into the instrument memory can be visualized and further processed on PC after transfer through serial link (RS - 232, RS - 485, CAN). Software Basic software equipment for management of KMB systems devices in MS Windows environment. RETIS provides features for logging of actual measured values from multiple devices, visualization and complete configuration. Downloaded data can be stored in archives, processed statistically or exported for further work. Program uses serial lines or Ethernet for communication and supports various media converters (modems etc.). Software for management of archived records form device memories. Data can be downloaded from devices across various communication lines to the PC and then processed. RETIS Off-line is a replacement software for CETIS32 with new devices and supports among others importing of old archived data from CETIS. |
