 The RMVC 5100 is designed for maximum reliability, efficiency and versatility – features that have a direct impact on the customer’s cost of ownership.

Multi-level features

Very low levels of input current harmonics with high input
power factor.
∙ Sinusoidal current output to motors – no significant
temperature rise in the motor due to current harmonics.
∙ No significant motor shaft torque pulsations – kind to shaft
coupling and mechanical load.
∙ Lower dV/dt voltage stress imposed on to the motor and
cable insulation systems.
∙ Lower amplitude of PWM switching at the output
significantly reduces potential transmission line effects
when long output cables are used to the motor.
∙ Lower amplitude and frequency of PWM switching at the
output significantly reduces potential for stray currents
through the motor bearings.
∙ Use of low-voltage IGBTs which are easily obtainable,
highly reliable and well-proven.
∙ Low losses since IGBTs do not need snubber circuits and
require little switching power.
∙ Current can be switched off instantaneously in the event
of a fault in the output circuit.
∙ Modular design.
∙ Medium voltage output achieved without output transformer.

Q:The laptop's power adapter is too hot to do
The original adapter heat should be no problem, the fan mouth is very hot, the weather may be more and more hot it!
Q:Laptop adapter
The first of the power to be large, not recommended to use the second to replace the other 90W adapter size are similar, but if the computer is not installed when the battery, 65W can also be used, as long as the interface on the Oh
Q:Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total
Which model ah, CE alarm, it should be communication failure. CE4, it seems that should be written to the read-only address. You follow the inverter model, to the Delta website to download the corresponding manual, there are fault alarm instructions.
Q:Three sets of batteries (540V) DC power supply U / f inverter.
It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
Q:The laptop's power adapter can be used on a desktop computer
that is the adapter is only one output input desktop machine needs a lot of different The interface can not be used completely Well
Q:A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole
First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
Q:How do I protect the inverter when the three-phase two-pole motor is running?
A: At this time to put the heart in the stomach, wait and see the change, what do not move (to prevent the accident to expand), until the motor stops, and then confirm, what kind of protection: alarm (alarm automatically after the release) or failure , Such as: over-voltage, overload, over-temperature, etc., and then the right medicine; inverter in the run which is not allowed, forced parking stop. Otherwise it will cause serious damage to the inverter.
Q:How can a variable speed multi - speed three - phase asynchronous motor be controlled by a frequency converter?
Although the waste, but can be used, we use the frequency band with two-speed motor when the output is connected to the fast three terminals, you can refer to the next
Q:How do I select a drive? Which brand is better
 Ampang letter company can provide different types of inverter, the user can according to their actual process requirements and the use of occasions to choose different types of frequency converter. When selecting the inverter, note the following precautions:     1, according to the load characteristics of the inverter, such as the load for the constant torque load; fan, pump load should be selected AM300 inverter.     2, select the inverter should be the actual motor current value as the basis for selection of the inverter, the motor rated power can only be used as a reference. Also should take full account of the output of the inverter contains high harmonics, will cause the motor power factor and efficiency will be bad. Therefore, with the inverter to the motor power supply and power grid power supply compared to the motor current increased by 10% and the temperature increase of about 20%. Therefore, in the choice of motor and inverter, should take into account the situation, the appropriate margin to prevent the temperature rise is too high, affecting the motor life.     3, the inverter to long cable operation, this time should take measures to suppress the long cable to the ground coupling capacitor, to avoid the inverter output is not enough. So the inverter should be amplified or selected to install the output reactor at the output of the inverter.
Q:The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?
Can be used, their rated current is not the same, the need to use the inverter over-current overload protection and other parameters for the corresponding changes.
