What is an ELV?
As per International Electrotechnical Commission (IEC)terminology, a circuit or a system that uses less than 50V AC or less than 120V DC is defined as Extra Low Voltage. Generally, these units are not connected to the main power supply of the infrastructure. Essential units that have lower power requirements come under ELVs and these units are expected to operate at all times hence they are isolated from the mainstream power supply. These ELV systems are further classified as SELV, FELV, and PELV from the application perspective. The low-risk factor of shock and the safety it provides to the adjoining circuits makes them an integral part of any sensitive installations such as labs, hospitals, etc.
A Separated Extra Low Voltage system is galvanically isolated from the earthing circuit and hence a fault in those lines will not bring any catastrophe. Medical instruments and swimming pools are the prime examples to use these ELV as per the norms of the local governance in Qatar. The cost associated with adequate double insulation, and high-quality raw materials is high but easily outweighs the safety aspect it provides in its implementation. A special audit is required on the functional side of a SELV as per EN 61558.
The PELV is similar to the SELV but it can have a ground connection for protection. However, the design of the unit should ensure low contact to high power units, like having thicker insulation between the primary and secondary winding of the transformer. A typical example is a metal-cased computer in a data center that works on a Class I power supply. In contrast, FELV doesn’t have any sort of protection and draws power from semiconductors or autotransformers. Typical examples include a toaster or a signaling unit in smoke alarms. Also, there is an RLV, Reduced low voltage which is primarily used for corded hand tools and any temporary lighting arrangement, especially in construction sites.
Key Areas Of ELV:
- Closed-circuit television
- Closed-circuit television
- Structured cabling
- Alarm Systems and Security
- Emergency lighting
- Access control system
- Public addressing system
- Office and home automation system
- Bollards, turnstiles, and barriers
- Network security
- Voice networking
- Nurse calling in hospitals
- Building management system
- Telephony, LAN, WLAN
- SMATV, IPTV
Extra Low Voltage is the lifeline for communication units, security, and sensitive electronic system installation in a building. The diverse usage of ELV batteries makes them an ideal choice for any electrical or electronic circuitry. Ideally suited for interoperability, these ELVs are an intrinsic part of security protocols across Qatar.
ELV Modules and Applications
A network of cameras monitored from offsite has to be on a separate loop from the main circuitry on many occasions and ELV is the perfect fit for the source power of these cameras and circuits. ELV can be sourced via batteries and transformers but the former is preferred on most occasions for the safety aspect. ELV-integrated closed-loop systems that operate independently are the most efficient way of keeping any sensitive premises secure.
Access control systems of infrastructure often use these ELVs as the doors, biometric system units only require a low-voltage source. The access control system often requires a complex network of permissions in large premises and a reliable, uninterrupted power like ELV is the only choice to accommodate such a stringent requirement. Once granted access the door is integrated with modules to save the access given and report it to a central unit along with the card details that gained the access.
A public addressing system often conveys key messages to all or particular units with emergency instructions. If at all a company vies for an ISO certification then there are a few mandatory emergency procedures that need to be installed in the premises like the emergency exit, and the route map to an emergency exit, all of which need to be lit even during an electrical breakdown. An ELV is an appropriate source for these units that handle the load even during adverse conditions and brings the people to safety.
Alarm systems that are set to go off whenever a threshold is reached often use ELVs as it is a vital part of any installation to avoid major accidents. Even a fence intrusion detection system uses these batteries while they send the exact location of intrusion to the administration. This includes the use of multiple sensors at regular intervals of the fence, and a coverage system from the cameras overlooking the fence so that whenever an intrusion happens the camera automatically points to that place. These are sensitive areas where ELV is just vital.
Importance of Battery Backup for ELV System
We understand the importance of having a reliable and efficient backup power system for ELV operations. Sealed Maintenance Free Batteries (SMF) are chosen as a backup power source and SMF batteries offer many benefits, such as:
- They are durable and can withstand harsh conditions.
- They require minimal maintenance and have a long lifespan.
- They have a high-performance rate and a low self-discharge rate.
- They can be recharged quickly and easily.
- They are environmentally friendly and do not emit harmful gases or leak acid.
By using SMF batteries, we ensure that ELV systems and critical equipment are always powered and protected. We are committed to providing the best service to our customers and partners, and we believe that having a reliable backup power system is essential for achieving this goal.
