The Fotek SSR-40 40A solid state relay is an electronic device designed for efficient and reliable control of electrical loads using a low-voltage control signal. This relay belongs to the category of contactless switches, which means it has no moving parts, ensuring a long service life and noise-free, spark-free operation.

Main features:

Control signal input: 3-32 VDC
Input current: 3-25 mA DC
Output voltage: 24-380 VCA
Rated output current: 25 A (with 3/2 safety margin for resistive loads)
On-state voltage drop: 1.5 V
Switching time: 10 ms
Average withstand voltage: 2500 VCA
Insulation resistance: 1000 MΩ / 500 VDC
Operating temperature: -30 to 75 °C
Installation method: screwed
Status indicator: LED

Advantages and benefits:

Long service life thanks to the absence of mechanical contacts.
Silent operation with no electromagnetic interference.
High switching speed and strong anti-interference capability.
Compact size, vibration resistance, explosion prevention and corrosion resistance.
Compatible with TTL, DTL, HTL integrated circuits, among others.

Typical uses:

This relay is ideal for controlling resistive electrical appliances, such as electric heaters, heating cables and heating pipes. It is especially useful in temperature control systems where a fast and precise response is required.

Important considerations:

It should only be used with resistive loads.
A 3/2 safety margin above the rated current is recommended to avoid overloads.
For currents above 5 A, it is essential to ensure proper heat dissipation, preferably with a heatsink specifically designed for solid state relays.

Compatibility:

Compatible with a wide range of electronic systems and controllers operating with control signals in the 3-32 VDC range, making it easy to integrate into automation and industrial control projects.

Note: This product is currently out of stock. Please check availability for future purchases.

Customer Questions & Answers

What is the Fotek SSR-40 40A solid state relay used for?

It is used to control resistive electrical loads such as electric heaters using a low-voltage control signal, offering a contactless switch with a long service life.

What are the technical specifications of the Fotek SSR-40 relay?

It has a 3-32 VDC control input, 3-25 mA input current, 24-380 VCA output and 25 A rated current, with a switching time of 10 ms and LED indicator.

How do you install the 40A solid state relay?

It is installed by screws on a suitable surface, ensuring proper heat dissipation, especially if the current exceeds 5 A.

What is the price of the Fotek SSR-40 solid state relay?

The price is 4 euros, although the product is currently out of stock and not available for immediate purchase.

What are the differences between a solid state relay and a mechanical relay?

A solid state relay has no moving parts, offers faster switching, produces no noise or sparks, and has a longer service life, while a mechanical relay uses physical contacts that wear out over time.
