Electronic%20Dual%20Timer
Electronic Dual Timer
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%20Automatic%20Sequential%20Timer
Electronic Automatic Sequential Timer
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.

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.
