Efficient
power quality management is fast becoming a necessity in present
competitive age. You may not even be aware that you bare losing
precious energy and profits due to:
- Poor quality of electricity
- Voltage variations & imbalance
- Inefficient use of motor
- Poor power factor
Our company specializing in power quality management. To
help you overcome these problems, we offer comprehensive range
of solutions as below:
- 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.
- 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.
- 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.
- CONEX SOFT STARTERS:
When you are faced with high starting current problems,
mechanical jerks & system
voltage dips, we offer simple & cost effective device
which can replace star-delta or auto-transformer starters
& work better. It gives a smooth voltage ramp, enabling
motor to come to full speed smoothly. It also eliminates
DG set tripping while starting motors.

| Electron tubes |
10% drop reduces Cathode emission by 40% |
5% increase |
| Rectifier loads |

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.

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.
