0 SL441C ZERO VOLTAGE SWITCH The SL441C is a symmetrical burst control integrated circuit in an 8 pin DIL package.
When used with a triac, AC power may be regulated by varying the number of mains cycles applied to the load in a fixed timing period.
The device is especially suited to room temperature control applications including panel heaters, fan heaters etc.
Zero Voltage Switching has the advantage of minimising radio frequency interference.
FEATURES s Balanced zero voltage point crossing detector, spike filter and pulse generator for reliable triggering of the triac.
s A period pulse generator and bistable which are arranged to provide symmetrical burst control and eliminate 1 / 2 wave firing.
(EN50.
006 BS5406,1976) s A ramp generator whose output is used to modify an internal reference voltage which is then compared with the voltage appearing on the thermistor to form a proportional control system.
The period of the ramp...
