Optional
Features:

Apart
from regular model SWIFT electronic auto phase shifter, we also offer
the shifters incorporated with EAPS-SL and EAPS, deluxe to fulfill
the exact requirements of our clients.

Models
Offered:

SWIFT
EAPS - SL

This
model is specially designed for 3 phase users. Who possess single
phase wiring & UPS users (up to 5 KVA single phase), For
UPS users (if they possess a 3 phase supply) UPS is connected to any
one of the phases. In case of that particular phase fails then UPS
changes to the battery mode.

If
UPS is connected through swift electronic auto phase shifter, when 1
or 2 phases fails swift gives continuous supply from the alive phase
automatically, thus enhances the life of the battery.

SWIFT
EAPS - Deluxe (DX)

This
model is available with high or low voltage cut off and if there is a
high low voltage in any of the phases (Deluxe) it shifts to the next
healthier phase automatically which enables smooth functioning of the
electrical gadgets. The operating voltage range is normally set
between 160 Volts & 250 Volts.

Swift
Electronic EB Gen Automatic Change Over

When
EB supply fails, this system automatically changes to the Genset
mode. When EB supply resumes it goes back to the EB mode &
automatically switches off the Genset (single Phase). 3 phase Genset
change overs can also be supplied against order.

SWIFT
EAPS EB GEN

This
model is the combination of automatic phase shifter & Genset
change over.

SWIFT
EAPS - DB / EAPS - DDB

Swift
Electronic auto phase shifter is also available along with the
combination of single door distribution board db & double door
distribution boards (DDB). These models fulfill the clients'
requirements of separate distribution boards.

We
offer high quality power watches, which are an electronic automatic
sequential timer and used for regulating the running time of air
conditioners, electrical motors, geysers and agricultural pump sets
more effectively and conveniently. These watches save energy by
avoiding continuous running of these electronic gadgets. Apart from
this, power watch comes as handy alternate for the clients who prefer
to invest on models with remote control facility.

Our
power watches are available with an initial in-built time delay of 3
minutes proper for all kinds of air-conditioners including the models
where auto cutoff timer provision is also available.

If
the rotary switch is kept in ON position, the A/c runs directly
by-passing this unit. If rotary switch is kept in OFF position, it
runs the A/c for selected ON time and switches it OFF permanently. In
the Bi-color LED, green indicates ON and RED indicates OFF, instant
start is provided to start the electrical gadgets without any time
delay.

Power
watches are provided with 2 rotary switches to set the ON time and
OFF time individually. ON time can be set in slabs of
15, 30, 60, 90, 120, 180 and 240 minutes whereas OFF time can be set in
slabs of 10, 20, 30, 45, 60, 90 and 120 minutes.

Power
watches are suitable for ACs of all models up to 2 Ton (Single
Phase) capacity & up to 3 HP single phase motors. Power
watches keep filling the O/H tank from ground water by automatically
operating the motor at desired time intervals.

We are one of the leading manufacturer and supplier of electronic dual meter which is time based energy saver for 3 phase Air-Conditioners. EEE comes in two varieties Dual and Triple timer models, which switches ON and OFF the compressor at frequent intervals alternatively and results in saving of power and money.

Working Principle:

When the AC is started, both compressors will be switched ON with in-built 3 minute time delay. After that, 1st Compressor will be switched OFF for 3 minutes after running for 20 minutes and again switched ON at 23rd minute. Alternatively, 2nd compressor will be switched OFF for 5 minutes after running it for 25 minutes and again switched ON at 30th minute.

By switching ON and OFF the compressors alternatively EEE saves considerable amount of power and money.

Electronic Automatic Phase Sequence Corrector gives an output of 3 phase supply in right sequence and always maintains 120° between phases, even when the input sequence is interchanged. This makes all 3 phase equipment continues to run irrespective of change in input phase sequence.

Salient Features:

• Fully automatic


• No manual
  intervention


• Single phase prevention


• High/low voltage protection


• Voltage
  imbalance protection between phases


• Output in the right
  sequence (R,Y,B)
