Application:

SSR Series solid state relay with flame-retardant plastic casing, epoxy potting, wiring screw terminals, with high structural strength, impact resistance, vibration resistance, the input drive current small can conveniently and computer terminals and a variety of digital programmable circuit interface, widely used in the automation and control of petrochemical equipment, food machinery, packaging machinery, textile machinery, machine tools, plastics machinery, fitness equipment, entertainment facilities.

Especially suitable for corrosion, moisture, dust, and other harsh environments require proof, and frequent switching of the occasion, AC contactor is updated alternative.





Safety Precautions:

1.the load current must be higher than 5A radiator or mounted on a metal base plate with the corresponding cooling effect, and coated with thermal grease between the solid-state relay heat the floor and the mounting surface, 40A above plus fan forced cooling or water cooling.

2.used when inductive loads, high transient voltages and inrush current is applied to the output terminal, which may cause the solid-state relay through misleading or damaged, usually require access at the output voltage with a specific clamping voltage control devices, such as two-way Zener diode or varistor (MOV). Recommended taking varistor 1.6-1.9 times the rated voltage.

3.the control close to the minimum load current is small load current load shall be parallel with the load on a dummy load resistor to reduce the output leakage current higher residual voltage at the load.

4.in order to avoid the temperature exceeds the allowable value of solid-state relays, the application should be designed to consider the cooling effect and the installation location, only when two or more solid state relays mounted side by side, you should leave appropriate spacing.

5.not in parallel between the output of more than just the use of solid-state relays in an attempt to increase the output current. But the output can be used in tandem in order to apply a higher voltage.

6.when using more than just a solid following the share when the control power inputs that can be used in tandem can be used in parallel.

7.capacitive load caution this piece, please select the capacitive load dedicated solid state relays.
