Show All Items We use batteries to power a lot of our electronics. But there are some battery powered devices that don't necessarily need to be portable all the time. One example is my son's battery powered swing. It can be moved around but it usually stays in the same general area. In cases like these it might be nice to power these devices with an AC adapter and save the batteries. So in this project, I am going to show you how you can use an old power adapter to power your electronics in place of batteries. I will share how to modify the adapter and two different ways to connect it to your electronic devices.Step 1: Use a Voltage Regulator Circuit to Set the Output of the Power Supply to the Appropriate VoltageShow All Items« PreviousNext »View All Steps DownloadIONI power supply schemes Jump to: navigation, search Two switching power supplies, one high power voltage supply for motor and one low power supply for logic circuity. A diode D1 is normally necessary to protect regenerative current flow going back to PSU1.

For recommended diodes, see paragraph below.car a/c compressor repair kit Wide motor supply voltage range possibleair conditioning unit ducted Switching PSUs typically don't allow temporary overloadingaverage cost of 4 ton ac unit Two similar high power supplies are used to supply both motor and logic voltages. In this system power of PSU1 and PSU2 will contribute to motor supply, i.e. if both supplies are rated 200W, then total power available to drives is ~400W. Diodes D1 is normally needed to protect power supplies from regenerative power and D2/D3 to protect power supplies in the case where one power supply would shut down (i.e. on overload). For recommended diodes, see the paragraph below. Cost saving (i.e. 2x200W 24V cost less than a 1x400W 48V)

In case of PSU2 fault/overload, drive 24V logic supply voltage may be instabilized (erratic drive behavior, or resetting drive) Linear (transformer based unregulated) power supply is used for motor supply and low power switching PSU for logic power. No need for diodes Linear PSU peak power handling Lower availability of linear power supplies Fluctuation of AC mains voltage may trigger overvoltage fault on drives if PSU voltage is normally near drive's maximum Single PSU (max 24V) is feeding logic and motor. Note: IONICUBEs logic supply can be fed anything between 9 to 24V, however some functionality (mech brake output, VFD output) may not work properly below 24V. If these features are not needed, then also lower voltage can be used. In case of PSU fault/overload, drive 24V logic supply voltage may be instabilized (erratic drive behavior, or resetting drive) Diodes D1-D3 are typical silicon or schottky rectifier diodes that are sufficiently rated to carry the present voltages and currents.

As diodes are inexpensive, there is no need to avoid oversizing them.

In normal inverters the time interval is too much such that if a computer is connected, that time gap is enough for the comp to switch off and lose its memory. So, here ups become important. They switch in milli seconds time so that the comp does not lose its data.A safe and reliable electricity supply is available to homes and business in remote South Australian towns through the Remote Areas Energy Supplies (RAES) scheme.Electricity is supplied to remote towns through the RAES State/Independent scheme, and to remote Aboriginal communities of Anangu Pitjantjatjara Yankunytjatjara (APY), Yalata on Aboriginal Lands Trust (ALT) and Oak Valley on Maralinga Tjarutja (MT) through the RAES Aboriginal Communities (AC) scheme.

The RAES State and AC service area covers approximately 210,000 square kilometres (which is roughly equivalent to the size of the United Kingdom) and experiences extreme weather conditions. Many communities are also geographically remote, eg Pipalyatjara is nearly 1600km from Adelaide, which can affect the networks.From 1 April 2016, the South Australian government has contracted Cowell Electric Supply to manage the RAES State and AC electricity networks. Cowell Electric Supply will maintain and operate the power stations and electricity distribution networks, and provide meter readings and retail services.Cowell Electric Supply holds the RAES State and AC generation, distribution and retail licenses issued by the Essential Services Commission of South Australia (ESCOSA).Around 2,400 customers in 13 remote towns are provided with more than 15 million kilowatt hours (kWh) of electricity annually.The South Australian government owns the electricity infrastructure that supplies 10 remote towns:Independent owner-operators supply electricity to customers in: View RAES communities in a larger map Each independent owner-operator holds generation, distribution and retail licenses issued by ESCOSA.

The state government subsidises costs for independent operators to make service delivery viable.Around 1,000 customers and consumers are provided with more than 14 million kWh of electricity annually.In the APY Lands, the Central Power House (located at Umuwa) is the primary electricity generation facility. It has a 33 kilovolt (kV) central distribution system that runs approximately 110km west, 70km north east and 170km south east.In the APY Lands, electricity is supplied by the Central Power House to:Power stations are also located within the following communities:Electricity is also supplied to Murputja (servicing Kanpi and Nyapari homelands), which is separate from the Central Power House grid and managed for the Commonwealth Government. View RAES Aboriginal communities in a larger map The South Australian government subsidises electricity tariffs for communities supplied under the RAES State and AC schemes. Tariffs are set based on the follow principles:Tariffs in Cockburn and Coober Pedy are different from other communities because of the way their electricity is generated and sourced.

The RAES customer connection and supply contract outlines the terms and conditions for the electricity supply to RAES State and AC customers.The latest RAES State/independent tariffs and RAES AC tariffs were implemented from the first meter read following 1 August 2015.Similar to on-grid customers, charges may apply for extra services, such as arranging a new connection or requesting final meter readings.New applications to connect to the RAES electrical infrastructure may attract a generation levy, depending on the connection capacity in kilovolt amp (kVA) being requested.The generation levy reflects the cost of providing additional infrastructure to supply the electricity. The calculation is:There is one 10kVA allowance per applicant per community per calendar year.Electricity used for public lighting in RAES communities is charged to the relevant council or responsible community group. Some community groups that are not part of Aboriginal Lands may be eligible to receive a subsidy for public lighting through the Outback Communities Authority.
