EC / BC / SYNCHROMAX — analogue panel instruments and generator synchronisation devices
Country: Spain · Model: EC / BC / SYNCHROMAX
Analogue panel instruments in DIN 48, 72, 96 and 144 mm housings and SYNCHROMAX digital devices for synchronising a generator with the grid. EC ammeters measure from 100 mA to 100 A with accuracy class 1.5. The instruments are installed in switchboards, on diesel and gas engine power plants, in ship electrical installations and on substation control panels.

Description
The analogue part covers AC ammeters and voltmeters (EC, CEC, EZC) and moving-coil DC ones (BC, CBC), single- and three-phase wattmeters (WMC/WTC, YMC/YTC), cos φ meters, pointer and reed frequency meters, maximum demand meters and synchroscopes for marine applications. Interchangeable scales adjust the reading to the transformation ratio of the current transformer. EC 96 measures the true RMS value, with a 90° scale, a consumption of 0.3–1.5 VA and a dielectric strength of 2 kV 50 Hz between the mechanism and the case. SYNCHROMAX measures the voltage and frequency of the generator and the grid in the range of 35–80 Hz and 110–600 V. All parameters are programmed from the front keypad, and there is a 4-digit display, 30 auxiliary LEDs and password protection. The modes are manual, automatic and assisted.
How to choose
The format determines the space on the panel, and the instrument type is chosen by the quantity you need to see, that is, current, voltage, power, cos φ or frequency. For synchronisation, SYNCHROMAX with a PI frequency adjustment algorithm is used, and when faster synchronisation is needed, SYNCHROMAX PID with a pulse output. The device supply is 110, 230 or 400 V AC. For metering and network analysis look at CEM-D / CEM-C or CVM-B100/B150.

FAQ
What is the measuring range of EC 96 ammeters?
True RMS value from 100 mA to 100 A, accuracy class 1.5, 90° scale. For higher currents an interchangeable scale is selected for the current transformer.
What overload do EC ammeters withstand?
1.2 In continuously, 5 In for 30 s, 10 In for 5 s and 40 In for 1 s.
Do EC ammeters need an auxiliary supply?
No, the instruments work without one. The exception is CEC 96 with a fully configurable alarm system.
What is SYNCHROMAX for?
For synchronising a generator with the grid in parallel operation of diesel generators, cogeneration units and small hydropower plants. The device compares voltage and frequency and helps close the contactor at the right moment.
How does SYNCHROMAX PID differ from SYNCHROMAX?
The base version adjusts the generator frequency with an integrated PI algorithm. The PID version has a more powerful algorithm and a built-in pulse output for fast synchronisation.
