Our company specializing in power quality management. To help you overcome these problems, we offer comprehensive range of solutions as below:

  1. CONEX SERVO VOLTAGE STABILIZERS:
    Voltage variations are major cause of energy loss, motor burnouts & equipment
    breakdowns. We offer CONEX SERVO VOLTAGE STABILIZERs from 1KVA to 1000KVA CAPACITY. These computer designed voltage stabilizers are energy savers with several unique features including guaranteed 98% efficiency and 100% continuous duty application. To overcome fluffy, dirty environments, we have specially designed them as sealed oil cooled units with separate plug-in type control panel. Alternately, air cooled units are also available.

  2. CONEX ISOLATION TRANSFORMER
    For conditioning of power for critical applications like telecom, automation, cnc
    machines etc. often there is a need of isolation ultra-isolation transformers either as independent units or in-built with servo voltage stabilizers. We have the capability to offer custom made solutions for every such application.

  3. CONEX AUTOMATIC POWER FACTOR CONTROLLERS:
    Improper load management and poor power factor cause several hardships such as
    high demand, high energy bills and high line losses. We offer automatic power factor controller with comprehensive power factor survey for assured automatic control of power factor to the set target value.

EFFECTS OF IMPROPER VOLTAGE ON EQUIPMENT

EQUIPMENT EFFECTS OF UNDER VOLTAGE EFFECTS OF OVER VOLTAGE
UPS systems low battery life failure
Electronics malfunction failure
Electron tubes 10% drop reduces Cathode emission by 40% 5% increase
Rectifier loads at 10% under voltage, plating rate drops by 20%, charging rate drops by 25% , welding time increases
by 20%
excessive heat generated. produces poor welds. Can reduce rectifier life substantially. Plating/
deposition may be uncontrolled.
Motors/Air Conditioning Overload and uneven heating/ low efficiency Overheating & power wastage
Lamps ,Tube Light, Heating Elements Low lux, reduced efficiency Higher failure/ high energy consumption due to overheating.
Process plants Increase in wastage of finished Product , stoppage of production Uneven quality.

Effects of improper voltage on motors

Unbalanced voltage causes inefficient
Utilization of motor, wasting power and
resulting in motor derating. For example,
a voltage unbalance of 5% between
phases will cause a 25% derating
in motor capacity. So, for same load, a much
higher capacity motor is needed.

Unbalanced voltage causes overheating of
motor resulting in reduced equipment life.
