L&T EX2000 Series AC Drives Description
The Ex2000 adds a new dimension to L&T's AC drive solutions. Built to L&T's stringent
quality standards. the Ex2000 is tested and certified to meet global benchmarks,
thus giving you the assurance of total reliability.
Specially designed for industrial applications, the Ex2000 is perfectly suited for
fan and pump applications. It can handle loads up to 450 kW, and is engineered to
keep your machine operating at optimum efficiency – even in the hot, humid and dusty
conditions that characterize India's industrial environment. It has features that
save energy and cost, and is easy to operate.

L&T EX2000 Series AC Drives Dual rating operation
- Designed to be used for heavy and normal duty applications.
L&T EX2000 Series AC Drives Overload capacity
- Heavy duty operation: 150% of rated current for 60 sec.
- Normal duty operation: 110% of rated current for 60 sec.
L&T EX2000 Series AC Drives Booster Pump
- It is used when a single drive is used to control multiple motors in pump systems,
by default 4 Pumps can be controlled & Max upto 8 pumps can be controlled.
- Precise Control of pressure.
- Ideal cost effective solution for constant pressure / constant flow pumping application.
L&T EX2000 Series AC Drives PID & Dual PID
- In the centrifugal fan and pump, PID control is provided as a standard function
in order to maintain a constant pressure, flow or level.
- Where external or cascaded PID control is required, the built-in dual PID algorithm
of the Ex2000 can be utilised to satisfy various system requirements.
L&T EX2000 Series AC Drives Sleep & Wake Function
- It automatically switches OFF Drive during user-programmed low- load conditions
and then to start-up again when process demand increases.
- It helps eliminate unnecessary operation at idle speeds, thus saving wear and tear,
as well as energys.
- PID Control
L&T EX2000 Series AC Drives Automatic Energy Saving
- Load change may incur energy losses. But the optimised flux control of the Ex2000
results in more outstanding energy-saving.
L&T EX2000 Series AC Drives Pre Heat Function
- It allows the drive to maintain residual heat in the motor, which helps eliminate
condensation in damp conditions when the motor is not in use.
- In the drive, an adjustable, low-level DC current is applied to the stator windings
either continuously or on a duty cycle basis.
L&T EX2000 Series AC Drives KEB
- During power dips or momentary power outage, the drive’s output can be maintained
by utilising the residual mechanical energy in the load as a regenerative source.
- The duration of the power-dip ride-through depends on the load characteristics.
L&T EX2000 Series AC Drives Removable Terminal Block
- In case of AC Drive failure, control card of the existing drive can be replaced
to new drive with wiring.
- Reduces the downtime of AC Drive replacement.
