ECA3G® Solutions for complex transient protection

We combine the technical innovation of ECA3G®and our internal expertise. We provide solutions for complex transient protection for various applications in different areas.

a) Military

The military equipment uses very sophisticated systems prone to abnormalities caused by overvoltage in the power system and signal lines. ECA3G® products have minimized shut-down times of national security system and subsequent financial losses.

  • Protection of 230/400 V power system
  • Protection of system up to 1000 Volt
  • Protection of Command Control, Computer & Communications, Intelligence, Surveillance and Reconnaissance (C4IS&R)

b) Antennas and Transmitters

Located in a rather exposed place, receiving and transmitting systems must withstand harsh atmospheric conditions during their working life. ECA3G® products ensure the best possible protection of technologies against lightning strikes and induced voltage and thus they significantly increase the operational reliability of technologies on transmission routes.

  • Protection of 230/400 V power system
  • Protection of aerial down conductors
  • Protection of communication lines

c) Photovoltaic (PV) Systems

PV system must withstand weather conditions as they are located in highly exposed places. ECA3G® products ensure the best possible protection against temporary overvoltage to provide trouble-free operation throughout their working life. Protection of PV power plants /PV technologies for residential houses and for factories / Off-grid PV technology.

  • Protection of DC and AC side
  • Protection of signal lines

d) Oil and Gas Pipelines

A very large system which is exposed to undesirable effects of lightning strikes, induction from parallel lines of MH, HV or stray current. These events negatively affect the technologies which are necessary for their trouble-free operation. ECA3G® products ensure the best possible protection of such technologies and significantly increase their reliability.

  • Protection of 230/400 V power system
  • Protection of system up to 1000 V
  • Protection of pipelines against induced voltage
  • Protection of access security, fire alarm systems, signal and communication lines

e) Industry and Commercial Buildings

Commercial building and industry feature a great number of sensitive technologies and appliances. ECA3G® products considerably increase their reliability and, consequently, greatly minimize shut-down times of production technologies and subsequent financial loss.

  • Protection of 230/400 V power system
  • Protection of system up to 1000 V
  • Protection of access security and the fire alarm system and CCTV
  • Protection of signal, communication lines, and data networks
  • Protection of aerial system

TESTING REPORT
STORAGE POWER SOLUTIONS

HESB partners with world reputable manufactures to offer competitive power back up technologies and solutions. The selection of products will depend on customer needs and requirements.

VRLA Battery

a) Battery for Telecommunication / Network Power

HESBoffers series of DC power rectifiers which have been designed for high power density and operating efficiency to significantly reduce capital expenditure requirements and operating cost. These rectifiers allow a high degree of power system flexibility through features like horizontal or vertical mounting, universal AC inputs, and a high degree of scalability to allow for future network growth.

b) Battery for Uninterruptable Power Supply (UPS)

UPS systems are important and have to deliver reliable backup power. The batteries must operate and consistently through numerous power outages. HarapanErat offers reliable battery ranges in both VRLA and flooded batteries specially designed for the high power requirements.

An uninterruptible power supply, UPS is an electrical device that provides emergency power to a load when the input source, typically the utility mains, fails. A UPS differs from an emergency power system in that it will provide instantaneous protection from input power interruptions by using batteries and associated electronic circuitry. UPS systems are used for traffic control, broadcasting stations, information system, process control, scientific and medical sites, and security installations.

Lithium-Ion Battery

Lithium-Ion battery series product can provide power batteries of standard capacity and can be customized according to customers need. Integrating verified high-quality cells and the Battery Management System (BMS) that highly cooperate with an electronic control system, the lithium-ion battery can ensure high reliability, long life, and durability of batteries.

Rectifier

a) 24V and 48V DC Power Rectifiers

HESB offers series of DC power rectifiers which have been designed for high power density and operating efficiency to significantly reduce capital expenditure requirements and operating cost. These rectifiers allow a high degree of power system flexibility through features like horizontal or vertical mounting, universal AC inputs, and a high degree of scalability to allow for future network growth.

Inverter

HESB inverters and static switches, combined with our DC power systems, provide a modular UPS for AC power backup. During normal operation, the system can operate in the economy mode in which the energy efficiency of the total installation can be optimized. In regions with AC utility challenges, the inverter system protects the auxiliary AC-powered infrastructure from AC mains fluctuations. In addition, the inverter system offers new opportunities for energy savings by providing backup AC power.

Uninterruptable Power Supply (UPS)

Our UPSs are designed to ensure that companies can protect their mission-critical applications by maintaining a steady flow of energy under adverse circumstances. An uninterruptible power supply is an electrical apparatus designed to furnish emergency power even when other sources of input power fail, and they are indispensable tools within a huge number of unrelated industries. Our UPS systems feature the following:

  • Leading AC-AC Efficiency
  • Fully redundant and configuration design
  • High input and output power factors
  • Low iTHD
  • Easily expandable without requiring additional hardware
