Welding set energy saver excellent microcontroller welding set energy saver saves considerable amount of energy on weld sets. Normally welding sets are kept continuously on, although welding operations are not carried out. During these periods the welding transformer draws the magnestising current or noload current which is not doing any useful work. Electronic sensing unit detects these non-weld periods and switches off the power to the welding transformer after a preset time interval and hence saves power during these periods. When welding operation is to be restarted , the operator just need to touch the electrode with the material to be welded and the unit instantly starts the weld which then can be carried on continuously. The non-weld period power loss on a 12 kva set will be approximately 1.5 kw to 2.0 kw per hour. So using energy saver there will be a saving of 8-10 units per shift considering normal weld cycle. Which gives a payback period of about 1 year. Welding set energy saver is merely a control unit depending on the capacity of the weld set suitable contactor has to be provided special features • reduced power bills • lesser payback period • better transformer life • easy installation • instant restart of weld • same control unit for single phase and poly phase sets • digital announciation of the weld conditions specifications 1. Operating supply : 415 v , three phase 2. Load sense : through current transformer 3. Weld control time : 1 - 60 seconds adjustable. 4. Weld restart time : instantaneous. 5. Digital annunciation : power on, energy save , weld run, bypass 6. Control relay contact rating : 5a

Cyclic load energy saver (auto del-star controller) excellent make cyclic load energy saver is equipment developed to save power on partially loaded a.c. Motors using del-star conversions. Many of the motors in industries are operated in partial (loads below 60%) or cyclic loads (like compressor, press, lathes), which consume excess power during the above said periods. their controller makes the motor to run in star, in these unloaded or partial load periods and automatically change over to delta mode when load is demanded, which results in 25-30% power saving during star modes operation. apart from saving of power during unloaded periods the controllers improves the power factor and reduces the maximum demand, the amount invested can be realized in just 6-8 months is the superior advantage of the controller. this can be used to save power on ring frames of textiles mills also.

Cooling tower energy saver introduction: excellent make cooling tower energy saver ‘ctes100’ is a micro controller unit designed to save power on cooling tower application. Normally cooling tower motors are switched on along with the main process applications to reduce the inlet water temperature, but some times the cooling tower motor run even after its job is over. I.e. In reducing the inlet water temperature. This can be saved. This cases a huge power wastage which can be saved. Features; saves power up to 40 to 50% bright led display lcd display temperature setting (0° – 99.9° c) accurate rtd, pt100 sensor for temperature settings. Very short payback period. Can be connected any capacity of cooling fan motor. Electrical bypass provided. Technical specifications: relay output : no contact, rated for 230vac5amps. 2 set point (high set – low set) temperature display : 0° – 99.9° c input power : 230 vac ±10%, 50hz. √ temperature control : automatic control with hystersis effect √ total running hours & minutes display

A c energy saver ‘excellent’ make micro controlled a c energy saver saves power on air condition units. The unit switches off the power to the a c equipment after a preset time. The ‘on’ time is automatically determined by the unit on the basis of the ‘off’ time adjusted by the user. The power saving can be around a minimum of 15 –20% of the power consumption. Digital annunciations of the status like on, off, staring delay, adjusted off time, on mode and off mode time are the special unique feature of our make. Specification : power input : 230v ac, 50hz. Starting delay : 2-3 min. On time : automatic off time : adjustable by the user announciation : digital seven segment display. saving data: with the average power consumption of 1.5 units per hour and operating 12 hours per day and with minimum savings of 15% the average payback period will be 8 –10 months. In winter months, the ‘off’ time can be suitably adjusted to give increased power savings.
