The Tense Solid State Relay SSR-40DD 3-32VDC in Pakistan is a heavy‑duty DC‑DC solid state relay designed for reliable switching of DC loads without mechanical contacts. It is ideal for industrial automation, control panels, DIY projects and machine upgrades where silent, high‑speed switching and long life are important. This SSR-40DD accepts a 3–32V DC control signal on the input side and can switch a DC load (output side) up to 40A (within rated voltage and with proper heat‑sink). Typical applications include switching DC heaters, DC motors, solenoid valves, LED lighting strips, power supplies and other DC loads in machines and control systems. The compact, panel‑mount housing with standard screw terminals makes wiring simple for electricians and technicians. Features: DC‑DC solid state relay rated up to 40A (model dependent) 3–32V DC control input for easy PLC or controller interface Silent, contact‑less switching with long service life Fast response and low electrical noise Compact panel‑mount design with screw terminals Specifications: Model: Tense SSR‑40DD solid state relay Control input: 3–32V DC Load output: DC (up to 40A, e.g. 5–220V DC as per label) Type: DC‑DC SSR, opto‑isolated input Mounting: panel mount with screw holes, requires suitable heat‑sink for high loads Uses: Switching DC heaters and heating elements Control of DC motors and pumps Automation of DC LED strips and lighting circuits Switching DC solenoid valves and actuators Industrial control panels, PLC and DIY automation projects Package Include: 1 x Tense SSR-40DD 3-32VDC
