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 specic 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 Umax = 440 V mains.
