We offer products for two basic functions of switching and HID lamp dimming.

1.  Nature Switch family for automatic control of outdoor lighting, and

2.. SAVE SWITCH family for late night dimming of HID lamps.

The core objective of all the products lies in Energy Conservation through automation offering the twin advantages of cost saving and emission reduction.  We recognize the need to offer solutions to reduce green house gases (GHGs). We are contributing to the above spirit through offering systems for improving energy efficiency in lighting normally called CDM project eligible for carbon credit under the guidelines of United Nations Framework Convention on Climate Change (www.unfccc.int).

Nature Switch: The mother of all our products.

This unique product is based on an infrared sensor and the fundamental decision is based on ambient light level for switching ON since it is almost a universal requirement for all outdoor lights. It switches ON the outdoor lights the moment the light level goes below 60 LUX. Once the natural sunlight remains below 60 lux for more than 30 seconds, the NATURE SWITCH will switch ON and ensures that the ground Illuminance of the required level is maintained. Similarly in the morning as the natural light level builds to 10 lux the unit will switch OFF the lamps after 30 seconds so that no more power is consumed unnecessarily. We also offer VISIBLE light sensor based SUN SWITCH for indoor light control.

NATURE SWITCH-01- DUSK TO DAWN CONTROL FREE FROM SETTINGS

This model is called NATURE SWITCH-01 and is particularly suitable to all those outdoor lights, which are ON during the entire night like street lamps, campus lamps, yard lamps etc. The product is offered with extra protective features like OVER / UNDER VOLTAGE sense, trip and auto reset etc.

NATURE SWITCH-02 -A VERSATILE HYBRID SYSTEM .

This model called NATURE SWITCH-02 is specially developed for applications like hoarding control, sign board control etc where normally the users want to switch OFF the lamps late in the night once the normal movement of the traffic slows down say by 11 PM or 12 o' clock in the night depending on the location, city, nature of traffic etc. In fact some of the street lamps can also be switched OFF by say 1 AM in the early hours. For example one phase may be OFF by 11 PM and the second phase by 1 AM and the third phase at dawn depending on the natural light level. These times also change in accordance with the season. Consequently the Nature Switch-02 offers a unique duration based selection for switching off of the lamps. This is expressed in terms of hours from the time of switching ON based on dusk. The selection is possible from 4 to 8 hours with a resolution of half-an-hour. The internal clock is quartz based for long-term stability. Input mains power failure will not stop the clock since a rechargeable battery is provided. This model of NATURE SWTICH-02 also switches on the lights based on natural light level at dusk irrespective of time. The switching OFF will take place as per user selection instead of at DAWN.

SWADEEP 02-EC FOR HIGHER LOADS

NATURE SWITCH models 01 and 02 can handle a direct lighting load of up to 3kW on one phase. It is customary and convenient to use power contactors if the load is more than 3kW. Power contactors are also used for switching load on all the three phases from a common switch. To facilitate an easy installation we SWADEEP-02 EC is offered in 6 models. This is an integral model offered with all the control gear, fixing arrangements, cable termination facility, lock and key etc. SWADEEP-02EC is offered as a pole mountable enclosure consisting of a light sensitive control system, power contactor for load switching, MCB, and terminal blocks. The enclosure comes complete with mounting brackets, cable glands, openable door with lock and key. The enclosure is made of UV stabilized, FR grade special molding compound to provide a rust proof, electric shock proof, termite proof, outdoor mountable electrically insulating body capable of enduring solar radiation in the outdoor. Selectable options are available for duration based switching OFF as well Override facility for maintenance

SIGN SWITCH

This product is specially designed for automation of glow signs and this provides for a very easy installation at the time of manufacture of the signage itself. The product has almost all the features of NATURE SWITCH -02 with a duration based over ride timer for switching OFF of the signage in the middle of the night itself at any time from 2 to 6 hours with 1/2 hourly resolution. This is a OEM model for use by all the sign makers. The key purpose of this model is to facilitate an easy installation and to eliminate the need for field visit.

SAVE SWITCH is offered as an intelligent and easy to fix solution for HID lamp dimming during non peak hours. The product is universal for HPSV and MH lamps and offers dimming upto 40% using the concept of bi-level or step dimming. SAVE SWITCH helps in maintaining the uniformity factor while energy conservation is achieved and the device offers the selection of the peak period duration from 1 to 9 hours. The conceptual basis is provided below for more details.

High intensity lighting is normally provided using HID luminaries like HPSV and MH lamps. They are often the preferred choice when large areas like road ways, parking lots, pathways, etc. are to be illuminated. The power rating of the luminaries is selected based on the illuminance requirements of the field during the early hours of the night. How ever the illumination level required will be less during the non-peak hours or during the late night..SAVE SWITCH is designed to meet this need automatically.

Save Switch uses the concept of Step-level dimming enabling wattage reduction to 60% of rated power. Step-level dimming is ideal for saving energy and providing lighting for safety and security during non peak hours. SAVE SWITCH also allows individual fixture control and is suitable for retrofit. Save Switch works with both HPSV and MH types of HID lamp types and is suitable for indoor as well outdoor usage..

SAVE SWITCH comes as a reliable, integrated, aesthetic and cost effective solution with a low pay back period. SAVE SWITCH ensures uniform illuminance level. SAVE SWITCH is installed in the junction box on a pole for outdoors. SAVE SWITCH comes in series to the input terminals of the control gear.The basic feature of SAVE SWITCH is to maintain the lamp in Higher Wattage (HW) for the selected duration from the time the lamp is switched ON in the evening and to shift the lamp to Lower Wattage (LW) till switched OFF in the morning. Any duration from 0 to 9 hours can be selected..
