230V Down Converter

We have a new cigarette plug style adapter which goes from 11–30V down to 1.5, 3, 4.5, 6, 7.5, 9 and 12 volts (1500mA).

12V Power Supply

We are now stocking a 40A switch mode power supply at a very good price. It is adjustable from 3 to 15 Volts and has an LED readout for Volts and Amps. It has overload, over temperature and over voltage protection. It is suitable as a 12V battery charger and it is very attractively priced.

Low Voltage Alarm

For those of you with Plasmatronic regulators, we have a very economical buzzer to warn you of low voltage.

Lampshades on PL Fluoros

The PL style 'U-shaped' fluoros are often mounted on the ceiling. The vast majority of their light output goes sideways and very little light is directed downwards onto your desk, table or the floor where you probably want the light. This can be dramatically improved by placing a conical shiny "Chinaman's hat" type of lampshade around it. White plastic or metal lampshades are best to direct and reflect this light. We sell these lampshades or you may be able to purchase them locally from department stores.

Reducing Fridge Power Consumption

With the summer coming on, I thought I might give you a tip how to reduce power consumption. Previous
newsletters have discussed using 12/24V compressor type fridges on solar installations. Contact our office if you need any more information in this regard. OK, let's assume you have an efficient 12/24V compressor fridge.

* Do not place hot food in it. Let the food cool down first to room temperature. If you are buying drinks to put in it, buy them cold if you can.

* The colder you run your fridge/freezer, the more power it will use – up to 5% more power for every one degree C colder you run it.

* If you are using an upright fridge (in particular) we suggest you try to keep it as full as possible. Having large air spaces in it means the fridge warms up much more quickly, especially when you open the door. On a sunny day, when you have lots of extra solar power, fill up your fridge with drinks or with containers of water. You can also fill up your freezer with ice cubes, 'esky packs' or containers of ice.

Having your fridge/freezer full like this means that it will not warm up as easily and you are making use of your solar power on sunny days.

That’s all for this month folks! Your comments and questions are most welcome; however there is no need to send our newsletter back to us when you reply! If you would like a price or product information, please tell us which country you are from if is not evident from your e-mail address. This allows us to assess if local GST (tax) is applicable or whether 230 volt 50HZ products will work in your country etc.

Also please note that the advertisement below comes from our server, Topica, and we do not necessarily endorse this product or service.

Cheers from Dave and all the RPC crew.

For larger system we also go up to Brisbane or down to Coffs Harbour and even Glen Innes. Other places by arrangement.

We are Open for Business

Rainbow Power Company would like to assure our customers that we are trading (not quite as normal). System designers are working from home and can customise a quote for you (free of charge) over the phone and online. We are still dispatching and posting items, with safety precautions in place. You can still order online or over the phone, and pick up items from RPC (our show room is closed however, and appointments must be made to pick up orders). We are still doing site inspections, keeping the recommended social distancing.

Contact us

This is the perfect time to start thinking about your power needs for the future, reducing your bills, and safeguarding against future power outages, so call today and get in before the oncoming solar rush. PH: 02 6689 1430 or send an enquiry
