Note:
In order to prevent electric shock, the motor and frequency converter must be
grounded before use.
• Do not install the incoming capacitor or surge suppressor, radio noise filter
to the output of the frequency converter. This will lead to the failure of the
frequency converter or the damage of the capacitor and surge suppressor. If any
of the above equipment has been installed, please remove it immediately. When
it is necessary to set a non fuse circuit breaker at the output end, please
consult the manufacturer for the selection of non fuse circuit breaker.
• With regard to electromagnetic wave interference, the input / output (main
circuit) of the frequency converter contains high-frequency components, which
may interfere with the communication equipment near the frequency converter
(such as AM radio). Therefore, EMC filters are installed to minimize
interference.
• For details of peripheral devices, please refer to the user manual of each
option and peripheral device.
• PM motor cannot operate on power frequency power supply.
• Because PM motor is a motor with built-in permanent magnet, even when the
power supply of frequency converter is disconnected, as long as the motor is
still rotating, high voltage will be generated at the motor terminal. When the
output switch is closed, turn on the power supply of the frequency converter
- Q:i have read different forums explaining what really is an isolation transformer but unfortunately i am having trouble on grasping the main idea? please help, why do they say that isolation transformer can help a person being electrocuted even if he touches one of the secondary terminals??? how is that??? thank you
- how does isolation transformer prevent a person from being electrocuted when touched the secondary? There are two common ways to get electrocuted by line powered equipment. Using an isolation transformer eliminates one of those ways. To get electrocuted electric current has to flow across your body, typically your heart. If you connect each of your hands to the output leads of an isolation transformer, you still get electrocuted. But there is another way to get electrocuted using line powered equipment. One side of the electric outlet is tied to earth ground, so if you touch something connected to the hot side of the wiring and have something else (like your other hand) connected to something that is grounded (like plumbing or a grounded appliance) you get electrocuted. The output of an isolation transformer floats the output in relation to earth ground, so if you touch some part of the transformer's output very little current will flow through you even if you are standing in water. You may wonder why I said very little current instead of zero current. The reason is that we live in an imperfect world where the insulation in the transformer may not be perfect and your body has a tiny bit of capacitance. For most purposes this doesn't matter but if you are dealing with medical equipment with electrodes attached near the heart, this sort of thing has to be addressed. A GFI outlet works in a somewhat related way. It compares the electric current in the hot and neutral lines in the socket. If these currents don't match, the assumption is that something is shorting the hot side to ground (maybe through you!) and cuts the power.
- Q:A 2200/220V, single phase transformer has the following resistance and leakage reactance referred to primary: R5.6 ohms, X22 ohms1. calculate V2, I2 and cos(2) when the primary is supplied with 2200V, 9A at a lagging power factor of 0.8. Neglect Io.
- Single-phase okorder
- Q:Rated capacity of three-phase transformer S = √3 * U * I
- Single phase transformer S = UI where U is the phase voltage and I is the phase current. When the composition of three-phase transformer, of course, is the three transformers add up, S = 3UI. Here U is phase voltage, I is the phase current. As the three-phase circuit to use the line current and line voltage calculation, angle and triangular connection is the same, when U is the line voltage, the phase voltage increases the root number 3 (1.732) times.
- Q:Rectifier and rectifier transformer
- The rectifier is a device that turns AC into a DC. Rectifier transformer is to provide the rectifier with the corresponding AC input power. Rectifier transformer is done AC / AC conversion, and rectifier is done AC / DC conversion.
- Q:Can someone all the Transformers stuff? I mean, I see a lot of stuff about 'G1' and 'G2' and I think I heard something about their being TONS and TONS of different storylines for it.Will someone name each storyline, and what G1 and G2 is, and please tell me the official canon usage?
- I'd like someone to explain these dumb Action movies to me too!!! :
- Q:Hi! Anything you wanna say about transformers, leave here!
- Transformers are cool!!!!!!! Transformers movie freaken awesome!!!!!! Transformers Animated its OK could be better, but still OK. Also can't wait until the next Transformers movie to come out!!!!!!!!!!!
- Q:I was wondering which comic is the best read for an ongoing series about the the Transformers? It can be old or newMarvel, Dreamwave, or iDW. I was just curious because I have been a huge fan of the franchise since the first set of figures and generation 1 cartoon series but never read a single comic about them (which is actually very weird considering I am a huge comic geek) and just wanted to check one out.
- transformers are crap why do you read them?!?!?!?!?!?!
- Q:1. 6volts going in a 12:220v transformeris the output 220v or less, formulas, computations 2. 12v going in 12:220v transformer (1 amp 220VA)core loss, copper loss, eddy current loss etc etc3. 24v going in a 12:220v transformer. is the 220v, lost of power in the input,
- #1 - 107.8, assuming 6.0V into a 12.0V:220V transformer, with 98% efficiency. You can find the efficiency of the transformer, by looking at it's specifications. Most range from 98 to 99%. All this depends on the load as well, as a lightly loaded transformer has less loss that a fully loaded one. #2 - 215.6V. In order to get 1A@220V, you will need to supply #3 - 431.2V. 100% over spec, and bound to fail. I do not understand what you mean by is the 220V, lost of power in the inupt,
- Q:actually we are trying to make a dc transformer,in which we want variable dc voltage at primary sidewe are doing this by using a rheostatwhich will change the value of current continously thus accordingly the value of voltage varyare we thinking right or wrong????
- Once you have converted AC to low voltage DC you can use the volume control knob off a radio or amplifier to vary your DC voltage on the secondary side. You could use a ceiling fan adjuster or light dimmer to vary the AC voltage on the primary side.
- Q:A CD player uses two 1.5 v batteries. If you want to plug it into a 120 v outlet, what kind of transformer will you need (Step up or Step down)? What must be the ratio of the number of turns in the primary to the number of turns in the secondary?
- You will need more than just a transformer to do the job. What you need is a power supply that has other components like diodes. and capacitors, As the other answerer said, it is easiest to buy a Universal Adaptor , with an adjustable (by switch) output voltage and output polarity and they come with an assortment of connectors. If you really want to build a power supply then first consider that the peak value of the 120Vac-?мs source 120√2 ≈ 170 volts. You need 1.5 + 1.5 3 volts (if the batteries are in series) so you'll need a transformer of about 170 ? 3 56:1 (stepdown) Depending on the filtering used, and the losses, and the actual voltage level at your home outlet (I've seen ?мs values from 110 Vac to 125 Vac), a 45:1 transformer would be better. The transformer must be rated at 60 Hz.
