2.- PRODUCT DESCRIPTION

The purpose of this manual is to assist during the installation, start-up and maintenance of

OPTIM HYB series low voltage (LV) capacitor banks with static operation. Carefully read the

manual to achieve the best performance from those units.

2.1.- CAPACITOR BANK COMPONENTS

From the electrical standpoint, the unit is made up of the following blocks:

2.1.1. HYBRID REGULATOR

The hybrid capacitor banks are equipped with Computer HYB hybrid regulators (Figure 3).

Figure 3: Computer HYB Hybrid Regulator.

This regulator has two types of outputs (see the inputs and outputs identied in Figure 4.:

 6 relay outputs with operating voltage of 250 V ~. and operating current of 4 A (AC1) for

the auxiliary control voltage of the electromechanical contactors that operate the three-phase

capacitors (three-phase steps of the OPTIM HYB capacitor bank).

 24 static outputs to provide a 12 Vdc activation signal to the + and - inputs of the CPC2

connection controller boards at zero voltage difference. These boards control the semiconduc-

tor modules (thyristor-diode) and operate the single-phase capacitors (single-phase steps of

the OPTIM HYB capacitor bank).

The Computer HYB also has the following notable features:

 The necessary information to calculate compensation demand by phase is provided by a

CVM-MINI-RS485-model power analyzer via RS-485 communications with the Modbus/RTU

protocol.
