This device makes possible to control the current and /or the Voltage in most of the A.C. power supply.
Electronics controller of current and /or Voltage AC input AC or DC out put.
Power supplies for resistive, capacitive or inductive load Using MOS technology.
It can protect effectively the sources and the load from over current and /or over Voltage�s overload by controlling and/or limiting the current output.
The regulation is obtained using a simple and inexpensive electronic circuit replacing advantage , equal to the existing dimmers using Triacs.orThyristors (NEW GENARATION)
The Power factor = 1 (the output current 100% is in phase with the input voltage
(resistive load only)
No E.M.C noises
Power Factor:= 1 (one)on all positions
Cost : equal to classics ones ( inclosing the cost of E.M.C. protection of the Triacs )
The control can be done either way : variation resistor, .D.C. voltage 0 to5 v. insolated from mains, feedback.
APLICATIONS
1) Variable speed control for AC/DC motor
or variable AC sources.
2)Dimming compact fluorescent light bulbs.
3) Start without overload of electronic equipment ( TV, computers,...)
4) Variable light intensity control with protection of overload and short-circuit.
5) Limitation of current in any type of circuit
6) Soft start of AC/DC motor
7) Stabilized AC/DC adapters, convectors.
