Description

The EL303X, EL304X, EL306X and EL308X series of devices each consist of a GaAs infrared emitting diode optically coupled to a monolithic silicon zero voltage crossing photo triac.They are designed for use with a discrete power triac in the interface of logic systems to equipment powered from 110 to 380 VAC lines, such as solid-state relays, industrial controls, motors, solenoids and consumer appliances.

 

Applications

• Solenoid/valve controls

• Light controls

• Static power switch

• AC motor drivers

• E.M. contactors

• Temperature controls

• AC Motor starters

dv-dt

The high voltage pulse is set to the required VPEAK value and applied to the D.U.T. output side through the RC circuit above.  LED current is not applied.  The waveform VT is monitored using a x100 scope probe.  By varying RTEST, the dv/dt (slope) is increased, until the D.U.T. is observed to trigger (waveform collapses).  The dv/dt is then decreased until the D.U.T. stops triggering.  At this point, ?RC is recorded and the dv/dt calculated.

dv-dt 公式

For example, VPEAK = 600V for EL306X series.  The dv/dt value is calculated as follows:

dv-dt EL3063
