With a power supply that takes 230 vac and converts it into 48 vdc. Depending on power requirements, the typical power supply contains a transformer to step down to an appropriate lower voltage, a rectifier to convert to pulsating DC, a filter to smooth the ripples out, and a regulator to fine tune to output voltage. In higher power applications, there might be no transformer. Instead there is a rectifier to produce high voltage DC, followed up by a switching power charge pump, which is modulated by the regulator to produce varying duty cycle pulsating DC into a large inductor, producing the DC. The switching power supply is very efficient, minimizing losses across the regulator, at the cost of more complexity. Most, if not all, modern computer power supplies are of the switching type and, even though they are more complex, they are cheaper to build and operate.

A: An easy way is to buy a transformer 230v to 50v and bridge rectify the output . There is power to be considered in any projects.

The 230 VAC has to be transformed down to 30 VAC and then rectified with a half or full wave diode bridge to change the voltage from AC to DC.

What is 30 percent off of 230 pounds?

161 pounds30% off of 230 pounds= 30% discount applied to 230 pounds= 230 pounds - (30% * 230 pounds)= 230 pounds - (0.30 * 230 pounds)= 230 pounds - 69 pounds= 161 pounds


What is the need for power supplies?

A power supply is needed to transform the line voltage (e.g. 120 VAC 60 Hz, 240 VAC 50 Hz) to the voltage or voltages needed by the equipment (typically DC voltages between 3 VDC to 300 VDC) depending on the operational requirements of the equipment. Some old vacuum tube equipment needed low voltage AC to heat the vacuum tubes, the power supply then also had to provide these voltages (e.g. 6 VAC, 12 VAC). I have seen power supplies as simple as providing just one DC voltage to power supplies as complex as providing 20 to 30 different DC voltages, some positive and some negative with respect to ground.


Is a 2 pole 30 amp circuit breaker equivalent to two single pole 30 amp circuit breakers?

Yes and no. Your electric panel has two bus bars. Each supplies 120 VAC. If you measure the voltage across these two buses you get 230-240 VAC. The buses are staggered top to bottom such that each breaker, top to bottom, alternates which of the buses they connect to. A 2-pole breaker would typically be use for 230-240 VAC service, but could be used for two 120 VAC circuits. However, in the latter case if either of the 120 VAC circuits tripped, both would trip. In the case of two single pole breakers, it would depend if they were connected to each bus or the same bus. However if used for a 230-240 VAC service you would want both to trip if either side tripped. This is done by joining together the handles of each breaker stacked on above the other in panel.

30 amp 230 VAC circuit can you run a 5 hp motor?

This answer depends on the characteristics of the motor. There are may different applications for motors and though the HP remains the same, the full load amps differ. If you have the FLA of the 5 HP motor then an answer can be given.
