CIRCUTOR OPTIM-EMS-C Series - Manual (Page 8)

2.- PRODUCT DESCRIPTION
The purpose of this manual is to assist during the installation, start-up and maintenance of
OPTIM EM-C series low voltage (LV) capacitor banks with static switching operation. Carefully
read the manual to achieve the best performance from said units.
2.1.- CAPACITOR BANK COMPONENTS
From the electrical standpoint, the unit is made up of the following blocks:
2.1.1. FAST REGULATOR
The static capacitor banks are equipped with Computer Max 6f V12dc fast regulators, which
have static outputs, that is, instead of an output via relay contact, these regulators have a sem-
iconductor-based switch, which enables them to perform operations in fast succession and in
practically every network cycle.
These outputs provide a 12 Vdc activation signal to the + and - inputs of the connection control-
ler boards, as opposed to the CPC4 type zero voltage.
Fast regulators enable regulation with minimum delay, generally between 20 and 100 ms (See
the manual or quick guide of the specific regulator being used)
2.1.2. CPC4 BOARD: ZERO SWITCHING STEP CONNECTION CONTROL
The static capacitor banks come equipped with CP4 boards.
The role of the CPC panel is to control the zero switching step connection of the thyristor-diode
modules, and so avoid connection current transients.
The standard connection diagram of a step can be seen in Figure 3 and with more detail in
section “7.- OPTIM EMS-C TYPE DIAGRAM”.
The CPC panels are activated via a 12 Vdc signal supplied by the 6f V12dc Computer Max
regulator outputs. The standard CPC4 is ready for U
max
= 440 V mains.
