SO843970

The SO843970 is designed as power solid state relay with output of 12 to 275VAC 35A and input of 20 to 265VAC/DC.

SO843970 has seven features. (1)Zero cross solid state relay designed for most types of loads. (2)Back to back thyristors on output with TMS2 technology for a long lifetime expectancy: 12 to 275VAC 35A. (3)Over-voltage protection on input and output (VDR) to have a high immunity according IEC/ EN61000-4-4 & IEC/ EN61000-4-5. (4)Very low zero cross voltage. (5)Large control range: 20 to 265VAC/DC with input current limiter. Green LED visualization on the input. (6)Designed in conformity with EN60947-4-3 (IEC947-4-3) and EN60950/ VDE0805 (reinforced insulation) -UL-cUL. (7)IP20 protection by flaps on terminals. That are all the main features.

Some SO843970 control characteristics are concluded into several points as follow. (1)Its control voltage would be min 20V and typ 110V to 230V and max 265V. (2)Its control current would be min 5mA and max 10mA. (3)Its release voltage would be min 5V. (4)Its input LED would be verte/ green. (5)Its input immunity: EN61000-4-4 would be 2kV. (6)Its input immunity: EN61000-4-5 would be 2KV.

Also some output characteristics of SO843970 are concluded as follow. (1)Its operating voltage range would be min 12V and typ 230V and max 275V. (2)Its peak voltage (VDR clamping) would be min 600V. (3)Its zero cross level would be max 12V. (4)Its latching voltage would be max 8V. (5)Its nominal current would be typ 35A and max 40A. (6)Its non repetitive overload current would be min 400A and typ 500A. (7)Its on state voltage drop would be max 0.9V. (8)Its on state dynamic resistance would be max 15m. (9)Its thermal resistance between junction to case would be max 0.6K/W. (10)Its off state leakage current would be max 1mA. (11)Its minimum load current would be min 5mA. (12)Its turn on time would be max 30ms. (13)Its turn off time would be max 30ms. (14)Its operating frequency range would be min 0.1Hz and max 800Hz. And so on.
