2. Power Backups

UPS Systems

In today’s corporations with wide spread use of information systems, networks and telecommunications, it is essential that the supply which powers critical system (s) is/are always clean and reliable, otherwise the result will be costly downtime and possible data loss. Insufficient or excess voltage, noise, fluctuations in frequency and wave distortion can be as harmful to modern electronic devices as power outages.

On-line dual conversion technology supplies protected devices with perfectly dependable sinusoidal energy, no matter what the quality of the incoming power supply, offering the best form of protection for all critical loads. Our UPS uses this technology to offer the best possible protection for all critical systems.

We have various series of these products in stock that we can offer based on the client’s requirements.

Features:

  • Advanced DSP/Microprocessor Design
  • Application of SPWM Technology in the design
  • Wide input voltage range
  • Active Power Factor – input 0.96
  • High Efficiency-Cold Start features
  • Rack and Floor mount models
  • Versatile communication options
  • SNMP Interface
  • Web enabled monitoring
  • Parallel redundant configuration
  • Galvanic isolation option
  • Extended battery back-up time option

This design can be used for ATM; Server Farms, Data Centre; Medical Equipment; Telecommunication Equipment; Switching and Communication devices; Process industry; Communication equipment; Computers; Hotels; Textile Machinery; Lifts, Elevators; Industrial Automation; and for Network Power Protection among others.

other power backup solutions we offer are Solar Hybrid Inverter and Batteries. Our Battery product ranges are Valve Regulated Lead Acid Batteries (VRLA), Energy Storage Batteries, Lead Carbon Batteries and Lithium-Ion Batteries.

As a proactive supplier, we continue to adopt new technology and add more product ranges to meet specific requirement of our clients. We have also established an effective dealership network in Nigeria in order to ensure our supply chain becomes more reliable.

4. Power Conditioning Systems

  • Industrial Servo Voltage Stabilizer (AVR)

Description

Voltage variations in supply line have become a common phenomenon causing havoc to sophisticated equipment like Computers, CNC Machines, Medical Equipment, Telecommunication Equipment, Industrial Automation, Communication Equipment, Military Equipment and so on. Our Servo Stabilizers manufactured by our foreign partners are designed to deliver a constant voltage, which remains within a very narrow band of +-1% of the nominal Voltage, thereby preventing failure of the connected load due to the aberrations in the supply line Voltage. The proven technology that combines solid electrical engineering ensures a continuous, smooth and very stable output Voltage irrespective of the supply voltage, load current or/and other circumstance.

  • Basic Principle of Operation

Our Servo Stabilizer employs a motor-driven variable Transformer feeding the primary winding of a line Transformer, for providing load safe Voltage at the output. The output Voltage is monitored by an electronic sensor and whenever the stabilized output Voltage deviates from the set value due to a supply Voltage or load current, the sensor energizes the motor to rotate the variable Transformer brush gear until the desirable Voltage is restored. This method of stabilization inherently produces no harmonics and therefore no additional harmonics is injected into the incoming supply. The durability and low cost of ownership make our servo Voltage stabilizers a very economical and reliable solution.

Basic Features

  • No waveform distortion
  • Speed of correction up to 35V/sec
  • Response time-less than 20msec
  • Power loss 2% max
  • Immune to load PF & supply
  • Frequency variation

Our other power conditioning solutions are Transformers, Automatic Power Factor Correction Panels designs, Transformer oil filtration machines among others.
