Features
Solid State Relay (SSR) is an advanced electronic switching device that can realize the function of DC control of AC. This product has many features, including current range from 0.5A to 400A, voltage range from 12V to 680V, compact appearance design, vacuum welding technology, LED indicator light to show working status, protective panel, compliant with IEC standards, optional Input and output types include DC/AC, AC/AC and DC/DC. Whether it is industrial automation, power systems or other fields, SSR series products have demonstrated excellent applicability and reliability, providing users with efficient control solutions.
Applications
- Solid State Relay (SSR) series products, such as SSR-10/25/40/60/80/100 DA, have a wide range of applications. These SSR products can be used in many fields such as AC DC switching and temperature control, automation control, CNC machinery, packaging machinery, textile machinery, glass machinery and plastic machinery.
Solid State Relay(SSR) is industrial control appliances which use power semiconductor devices for main control part, compare with traditional magnetic contact industrial controllers, it is more high-powered, intelligent.digital, systematic and green development.
according switch mode SSR have zero-cross and random type. When the input control signal, random type conduction immediately, zero cross type need load voltage turn to zero region just can conduction, Revocation of the control signal,all can cut off when less than maintenance current. zero cross type may cause the maximum half-cycle delay, but reduces the impact of the load and radio frequency interference, is the ideal switching devices.Random type fast response,suitable for dimmer,thermostats resistive loads and some inductive load applications.
When the SSR turn off, if in the phase current and voltage have different will have a large rise rate (dv/dt) on the triac, such as dv/dt higher than Triac standatrd (300V/us), will result in delay shutdown even failure. use anti-parallel thyristor's SSR(powerful type) will been greatly improved at dv'dt(dv/ dt is 500V/us). Therefore, in the field of capacitive load or inductive load,suggest the use powerful type SSR, Zenli's SSR are all powerful type.Solid-state voltage regulator consists of thyristor switching circuit,resistance-capacitance phase shifting circuit,lag circuit and over-voltage absorption circuit.The use of only one external potentiometer can be used to achieve AC power regulation.In many occasions can replace the heavy contact voltage lighting power supply,voltage,temperature,brightness,speed and other analog adjustment.

Notes
1.Strictly prohibit for load short circuit,Can use fast fuse.
2.Ling time working current can't over 70% of the nominal value.
3.Heatsink temperature can'tover75℃.
4.Use at inductive load area, add varistor for protect is better.
