Product catalog summary

Overview
This document serves as a general catalogue for digital power factor controllers by EL.CO. S.r.l., detailing various series, specifications, and features. The company reserves the right to modify specifications without prior notice.

Series and Specifications

EPFC-01 Series: A single-step controller with a 230VAC power supply, adjustable power factor, and options for manual or automatic operation. It includes a 4x LED red display and measures inductive and capacitive COS, voltage, current, and alarms.
EPFC-96 Series: Available in 4 and 6 steps, with a power supply range of 230-415VAC. It features a 3-digit 7-segment LED display, measures phase-to-phase voltage and current, and offers programmable functions and alarms.
EPFC-144 Series: Offers 4, 6, 8, and 12 steps, with similar power supply and measurement capabilities as the EPFC-96 series. It also includes a 3-digit 7-segment LED display and a programmable fan relay.
EPFC3-144 Series: Available in 6 and 12 steps, with a three-phase programmable power supply. It features a 3-display 4-digit 7-segment LED, measures three-phase voltage and current, and includes programmable functions and alarms.

Common Features

All series support manual or automatic operation and have adjustable sensitivity.
They measure real, reactive, and apparent power, harmonic distortion, and ambient temperature.
They include programmable functions and alarm relays, with a fan relay option for certain models.

Technical Data

Operating temperature ranges from -10°C to +50°C, with storage temperatures from -30°C to +70°C.
All models have an isolation voltage of 4kV and a protection degree of IP 41.
They conform to EC standards IEC 60255, IEC 60068, and EN50081-1/EN50082-2.

Installation and Interface

Compact size for easy installation on DIN rails.
USB and RS-485 serial interfaces for remote PC connection.

Technical Specifications
The controllers have dimensions of 149 x 149 x 60 mm and weigh between 720 to 770 grams. They are designed for three-phase mains and include auxiliary supply relays.

USB and RS-485 Serial Interface
The AD series interface supports a power supply voltage of 230 VAC with a range of -15% to +10%. It operates at frequencies of 47 or 63 Hz and has a maximum power consumption of 1.8 W. The interface supports Modbus RTU and ASCII protocols with a baud rate of up to 115.2 kbit/s, allowing connection of up to 99 devices.

General Features
The interface provides surge protection on the RS-485 line and supports remote connection to a PC via USB. It is compact, easy to install on a DIN rail, and includes indicators for power and data flow.

Thyristor Modules for Dynamic Power Factor Correction
The ETM series modules are available for different connection types (Delta and Star) and support maximum reactive power up to 75 kVAR. They operate at a frequency of 50/60Hz and include features like zero crossing commutation and over-temperature protection. The modules have an IP20 protection rating and are equipped with LED indicators for power and alarm status.

Connection Types
The document details various connection types, including bi-phase triangle and three-phase star connections, and control options through open collectors, dry contacts, or Modbus connection.
