Bravo Solutions is proud to introduce the Patented energy saving product portfolio baed on KillerWATT Technology. The “Programmable Energy Saver” is named as KillerWATT . This innovative new product opens a new horizon in energy saving in home and industrial appliances. Everything you need to save power at home/shop is built into one single and compact unit. The user can easily program the amount of saving into the device and easily control the electricity bill. 

KillerWATT Std 5A operates from 230V 50Hz AC (180V – 250V supported). It can handle a load of 1200W.

The built in Level-1 Surge protector circuitry protects your appliances from unwanted power line surge voltages. This feature is typically important for residents of industrial areas.

KillerWATT has a built-in Startup Delay circuitry that gives a 4 minute delayed power ON during a power failure. This feature protects your fridge/Freezer against intermittent and sudden power failures. 

The built in Power Sensor circuitry monitors the power consumption of the connected device continuously and determines the Optimal Power Point for doing the Switching. Simple timers does not have this feature and can damage the connected appliance during switching.

KillerWATT is NOT another Power Factor Correction technology, which is not appliacable with Sri Lanka’s Domestic Energy meters.

Below is a Video of a  Rupavahini TV programme in Sinhala that describes the theory and practical applications of KillerWATT. 

Connect the supplied power cord to the wall socket. Connect the appliance for Energy saving to KillerWATT’s plug bases. Bravo KillerWATT Std 5A is designed to handle a maximum load of 5A. Therefore DO NOT connect appliances that require higher currents.

KillerWATT Std model is optimized for Refrigerators, Bottle coolers and Deep Freezers. Therefore the user should have a better understanding of the product in order to use it for other appliances.

The user has to select the best Energy Saving Level out of 9 pre-programmed levels. The methodology of selection is described in detail in the user manual.

If you already have a Power Guard installed, then the KillerWATT should be installed in between the refrigerator and the existing Power Guard. Power Guard is not essential for the KillerWATT to operate smoothly but having one is always desirable. If you don’t have a Power Guard, then you can consider buying our KillerWATT Pro 13A which has a digital Power Guard built-in. Then you will get the protection and energy saving from one single unit which is economical and convenient.

Frequently Asked Questions (FAQ)


1. What Power of Fridge /Freezer can be connected to this product ?

Normally this product can handle any type of Fridge or Freezer. For higher powered Freezers  you can consider buying “KillerWATT Pro 15A”.

2. Is the turning ON / OFF the Fridge not harmful for the compressor

The built-in thermostat of the Fridge is also turning the compresser ON and OFF according to the set temperature which has no harmful effect by the design of it. We do time switching and this makes the number of ON/OFF transitions lesser than the native method. Therefore it has no harful effect on the compresser. 

3. What Plug types are available with this product ?

Our new products are manufactured with the 13A power socket as per government recommendations. But we do have a limited stock of 5A round type for your special requirements.

There is no recommended pattern. It is decided by your requirement. The user manual contains more guidance on this subject.
