SSR-40DA SSR Solid State Relay Module Output AC 90-480V Input for DC 3-32V 40A

Contact form Rated voltage conversion AC24-380 (V) Small form factor DC current nature Power Load Power Protection Features Closed Rated operating frequency 50/60 (Hz First, the product features: 1, triac output, zero voltage turn, zero current turn-off; 2, the optical isolation between input circuit and output circuit; 3, input - output isolation voltage between 2500V; Second, the product application: SSR Series solid state relays with flame-retardant plastic shell, epoxy potting, wiring screw terminals, with high structural strength, impact resistance, anti-vibration and strong, small can conveniently input drive current with computer terminals and a variety of digital programmable circuit interface, widely used in automation and control petrochemical equipment, food machinery, packaging machinery, textile machinery, machine tools, plastics machinery, fitness equipment, recreational facilities and so on. Especially suitable for corrosion, moisture, dust, requiring explosion-proof harsh environment, and frequent switching of the occasion, AC contactor is updated alternative. Third, the safety precautions: 1, the load current must be higher than 5A radiator or mounted on a metal base plate having a corresponding cooling effect, and applying thermal grease between the solid-state relay heat dissipation plate and the mounting surface, 40A above plus fan forced cooling or water cooling. 2, using inductive load, high transient voltages and inrush current is applied to the output terminal, which may cause the solid-state relay or misleading links damage usually requires access to the output voltage with a specific clamping voltage control devices, such as two-way Zener diode or varistor (MOV). Varistor recommend taking 1.6-1.9 times the rated voltage. 3, the control close to the minimum load current is small load current load shall be on the load in parallel with a dummy load resistor to reduce the output of the leakage current high residual voltage across the load. 4, in order to avoid the temperature exceeds the allowable value of solid state relays, design applications should consider the installation location and cooling effect, only when two or more solid-state relay mounted side by side, should leave appropriate spacing. 5, can not be connected in parallel between the output of more than just the use of solid state relays, in an attempt to increase the output current. But output can be used in tandem, in order to apply a higher voltage. 6, when using more than just a solid-state relay when a common control power input which can be used in tandem can also be used in parallel. 7, the capacitive load caution this piece, please select the capacitive load dedicated solid state relays.
