Frequency and voltage monitoring relay HRN-100

Multifunction voltage and frequency monitoring relay with LCD display for protection of devices connected to 3 phase network.

 Advantages:

• 3-wire or 4-wire connection (with or without neutral)
• Monitoring of upper and lower voltage & frequency in 3-phase circuits, phase sequence, failure and asymmetry incl. neutral fail (only in 4-wire connection).
• The device is supplied from monitored voltage.
• Both output contacts can be set individually.
• Measures real effective value of AC voltage (True RMS).
• Optional response delay of the output contact to the measured fault state or transition from the fault state to the OK state incl. delayed response of output contacts after connecting the power supply
• Optional closing or opening of the output contact when measuring a fault state (Fail Safe / Non Fail Safe).

Ensuring Electrical Safety in New ADRIA Mobile Homes

ETI offered comprehensive solutions of electrical installations for ADRIA's innovative new line of mobile homes,.

E-mobility: Electric chargers - part 2

The most efficient and safest method for charging electric vehicles for home use in accordance with the IEC 61851-1 standard is AC mode 3, either a single-phase or three-phase connection with different power ratings.

Programmable staircase switch CRM-46

Staircase switch enables delayed switching off of lighting on stairs, corridors, entrances, common areas or for delayed running of fans in the toilet or bathroom:

Advantages:

• 1 TE size, DIN rail mounted.
• Supply voltage: AC 230 V
• Long press (> 2 s) can switch off the output prematurely and end the ongoing delay.
• Control input with the possibility of loading up to 100mA load (glim lamp, LED in the button, etc.).

New residential projects in Poland;  A Closer Look at Three Prominent Projects

Introduction

Residential buildings in Poland are embracing the integration of advanced products, revolutionizing the way people live. Collaborative efforts between prominent companies have resulted in the implementation of innovative solutions that enhance comfort, efficiency, and sustainability within apartments. In this article, we delve into three notable projects, Bonarka Living, Hemma Orawska, and Mogilska Activw Investment, shedding light on the integrated products used in these residential complexes.

Bonarka Living

E-mobility: Electric chargers

E-mobility is booming; alongside electric scooters and bikes, we are also seeing more and more electric cars. There are several types of hybrid electric vehicles on the market: hybrid electrical vehicles (HEVs), plug-in hybrid vehicles (PHEVs) and battery electric vehicles (BEVs).

SSQ Modular changeover switch

Modular changeover switches SSQ I-0-II (network - generator) enable simple and trouble-free switching of power supply sources in case of emergency (e.g. mains voltage failure). They are designed for installation in switchgear equipped with TH35 rails adapted for mounting modular devices. Switches can be sealed for the selected positions: I or II.

Advantages:

• the family of SSQ changeover switches expands the EVE modular system range,
• all changeover switches are made in modular form - module width 18 mm,
• the distance between the changeover switch contacts in the open state is larger than 3 mm per one pair of contacts, (two pair of contacts in the current path of changeover switch)
• the changeover switches are equipped with terminals enabling connection of conductors of cross-section : 16 mm2 for a “wire” type wire; 10 mm2 for a “ stranded wire” type cable.

ETI Sponsors National Competition of Secondary Schools of Electrical and Computer Engineering

On March 28th, the National Competition of Secondary Schools of Electrical and Computer Engineering took place. This competition was sponsored by our company, and it attracted participants from 16 secondary schools across the country. The event was divided into four categories, including electrician, electrical engineer, computer technician, and computer engineer.

Photovoltaics Array protection

When we talk about photovoltaic installations for voltage up to 1500V DC, we can mean different types of solutions and ways to implement them in reality. There are several ways to convert DC voltage to AC voltage.
