Thakur angre offers llow power solid state relays are offered by thakur angre. These relays are suitable for pcb mounting. Using taecl technology, these 48 dat 4 z type ssrs are manufactured using taecl technology which guarantees a low thermal resistance from the power chip and a high surge current capability. Following are some of the technical features which include: this particular package has current range of 4 amp, 5 amp, and 7 amp, with mains voltage types 240 and 480 v ac. The. Principal characteristics of these relays are very high immunity to dv/ dt, and very low leakage current. By using optocoupler, thethe electrical isolation between input and output is provided by using optocoupler. The optocoupler also provides tthe interface is also provided by the outocoupler to the logic level dc input signal;. The input dc terminals and output ac terminals are in the form of plated copper pins which can be easily soldered to a printed circuit board. These relays are able to switch capable of switching power at zero crossing or randomly. These ssrs are ideal replacement for power reed relays in microprocessor or computer based logic level systems and are designed for long, reliable service in demanding industrial environments. Basic advantageous featuress are include: noise-free operation, compact and coated, high immunity to corrosive environment, almost unlimited number of operations, high speed switching low leakage current, high dv/dt strength, and low mains distortion. These solid state relays find their applications find use in areas such as ovens, extruders, injection moulding presses, heating light signboards and light spots, automatic operations, motor control, electrovalves, brakes, foodstuffs industry, packaging industry, house automation, show business, traffic signal control, and medical equipment.
