Featuring a clear LED status indicator and ultra-fast switching speed, it ensures reliable, silent, and spark-free operation. CE certified and optimized for integration with PLCs and microcontrollers, this relay demands proper heat sinking for loads above 10A, making it a trusted choice for high-performance industrial and commercial electrical switching. ## Description Heschen SSR-40DA Solid State Relay Single Phase 40A 3-32VDC to 24-480VAC | 40a single phase dc to ac solid state relay, 4-32vdc input, 24-480vac output, led indicator, ce listed for automation : desertcart.co.uk: Business, Industry & Science Review: Works as advertised - Appears to work fine, the relay was activated with a voltage between 2.5-5v DC, though it's obviously rated much higher. Only used it to switch 220v at 3A AC, can't comment on higher currents but it seems well built and works as advertised Review: very fast delivery and good quality. - Amazed the quality and the price so mutch. Cant say China just only make things to quantity. ## Features - 40A Solid State Relay: Model SSR-40DA. Single-phase DC to AC solid state relay rated for 40A load current, providing reliable switching without mechanical moving parts - DC Control / AC Load: Driven by a low-voltage 3-32VDC control signal, switching high-voltage AC loads ranging from 24V to 480VAC (50/60Hz) safely and efficiently. - LED Status Indicator: Features a clear LED working status indicator and a transparent protective cover, allowing operators to monitor the relay's operation instantly - High Switching Speed: Offers fast switching capabilities with low noise, spark-free operation, and anti-vibration performance. Easy to integrate with PLCs and microcontrollers - CE Certified & Thermal Note: CE listed. NOTE: For safe operation, this 40A SSR generates heat and MUST be mounted on a suitable aluminum heat sink with thermal grease when load exceeds 10A ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071HP9NJD | | Best Sellers Rank | 15,575 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 4 in Solid State Relays | | Brand | Heschen | | Coil Voltage | 4 Volts (DC) | | Connector Type | Screw | | Connector type | Screw | | Contact Current Rating | 40 Amps | | Contact Material | Copper | | Contact Type | Normally Closed | | Contact material | Copper | | Contact type | Normally Closed | | Country Of Origin | China | | Current Rating | 40 Amps | | Current rating | 40 Amps | | Customer Reviews | 4.2 out of 5 stars 421 Reviews | | Item Highlight | 40a single phase dc to ac solid state relay, 4-32vdc input, 24-480vac output, led indicator, ce listed for automation | | Manufacturer | Shanghai Kunerjing Current Rectifier Co.Ltd | | Manufacturer Part Number | SSR-40DA | | Minimum Switching Voltage | 4 Volts (DC) | | Model Number | 40A SSR-40DA | | Mounting Type | Screw Mount | | Mounting type | Screw Mount | | Number of Items | 1 | | Number of Terminals | 2 | | Operating Time | 0.01 Seconds | | Operation Mode | Automatic | | Specification Met | CE | | UPC | 670534168554 | | Wattage | 4800 watts | ## Product Details - **Connector type:** Screw - **Contact material:** Copper - **Contact type:** Normally Closed - **Current rating:** 40 Amps - **Mounting type:** Screw Mount ## Images ![Heschen SSR-40DA Solid State Relay Single Phase 40A 3-32VDC to 24-480VAC - Image 1](https://m.media-amazon.com/images/I/71c5WTzNEIL.jpg) ## Available Options This product comes in different **Size, Item Package Quantity** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as advertised *by F***R on 12 August 2020* Appears to work fine, the relay was activated with a voltage between 2.5-5v DC, though it's obviously rated much higher.
