From the day of commencement, we are engaged in manufacturing, supplying, trading and exporting Thyristor Power Controller. A thyristor is a semiconductor device which acts as a switch, which passes current in one direction, when it is switched on and to switch on the alternative current, two devices should be connected in inverse parallel. To meet the variegated demands of customers, these controllers are available in different specifications as per the needs and requirements of customers. The Thyristor Power Controller offered by us is available at market leading prices.
Other details:
-
Thyristor units start at 3A
-
Sizes up to 2600A and 690Vac
Products Variety:
-
Three Phase (2PH) 2-leg:
Single Phase Thyristor Power Controllers:
-
A range of thyristor power controllers to switch single phase loads.
-
Ideally suited for normal or variable resistive loads and transformer & inductive load types
-
Each device is turned on at the appropiate time by a trigger pulse applied to the gate
-
The device will remain on until the instantaneous load current through it drops to zero
-
The trigger pulses are generated by a driver, which times the pulse
-
Ensures the thyristor unit output is a function of the input demand signal firing mode
The Basic Firing Modes:
Zero Crossing (ZC):
-
Used with the logic output from a temperature controller
-
The cycle time is determined by the temperature controller
-
ZC minimizes interference due to the fact that the thyristor unit switches ON and OFF at zero volts
Burst Firing (BF):
-
This firing is performed digitally within the thyristor unit at zero volts, producing no EMC interference
-
Analogue input is necessary for BF and the number of complete cycles must be specified for 50% power demand
-
This value can be between 1 and 255 complete cycles, determining the speed of firing
-
When 1 is specified, the firing mode becomes Single Cycle (SC)
Single Cycle (SC):
-
SC is the fastest zero crossing switching method
-
At 50% input signal, one cycle is ON and one cycle is OFF
-
At 75%, 3 cycles are ON and one cycle is OFF
-
If power demand is 76% the unit performs the same as for 75% but every time the unit switches ON the microprocessor divides 76/75 and memorizes the ratio
-
When the sum is one the unit delivers one cycle more to the load
-
With this firing it is necessary to have an analogue input
-
SC is ideal for simple resistance loads
-
Thermal mass of the load is small or as a low noise alternative to PA firing with some applications
