Solid state relay PDH serious solid state relay flame resistant engineering plastic case,epoxy resin encapsulation,screw thread educting terminal connection with high-strengh structure,impluse resistance,high shock resistance performance,small driving current for input terminal and covenient connection with computer terminal and digital control circuit,the product is widely used in automatization control fields such as petroleum,chemica industry,instrument and meter,pharmacy machine,food machine,packaging machine,textile machine,plastics machine,numerical control lathe,entertainment facility,ect,especially for severe environment full of corrosion and moisture or requiring explosion-proofand dust resistance or place demanding frequent switching.
1.Resistive load could not exceed 60% of the rated current.
2.Inductive or capacitive load could not exceed 40% of the rated current.
3.Electric machine load could not exceed 20% of the rated current.
4.Proper radiator adapted to the working requirement of solid state relay should be equipped, the allowance should be widened when the load radiating condition is not so good. Short-circuit load is not allowable.
5.Over Current Protection: over current and short circuit are the main reasons for permanent damage of output controllable silicon in the relay, and using fast fuse and air switch is one of methods for over current protection, fuse is also available for small capacity.
6.Over Voltage Protection: It can adopt parallel voltage-dependent resistance(MOV), the MOV area decides the absorption power, while its thickness decides the protective voltage value, generally, 471/10D voltage-dependent resistance for 220V series PHD, 681/10D voltage-dependent resistance for 380V series PDH, 821/10D voltage-dependent resistance for 480V series PDH.
Voltage range: 24-380VAC; 24-480VAC; 240-660VAC ; 24-1200VAC ;
Current range: 5-120A
