## Description

Specification: Product Name: SSR-40DD Solid State Relay Control Current: 3-35MA Control Voltage: 3-32VDC Load Voltage: 5-200VDC Rated Current: 40A On-state Buck: ≤1.6V On-off Time: ≤10MS Ambient Temperature: -30°C ~ +70°C Product Weight: 0.1KG

## Features

- 【Optocoupler】: Core components of solid state relay quick switch speed, withstand voltage high.
- 【High Strength Screw】: High toughness anti rust screw material, not easy to break sliding wire. The column is made of red copper do.
- 【Rugged Case】: Excellent high temperature resistance is adopted for the shell. Burning material, bright luster, durable.
- 【Special Plating】: High purity copper base plate obvious heat dissipation effect, long time. It is not easy to heat when used between rooms.
- 【Note】Note: The solid-state relay generates a lot of heat. When the load current is greater than 10A, it needs to be used with a radiator. Apply thermal grease between the solid-state relay base plate and the radiator, and the fan is forced to cool if it is above 60A.

## Questions & Answers

**Q: 1. Normally open switch? or normally closed switch?
2. input current required to engage the switch? I know the load side handles 40A.**
A: Solid State Relay AC to AC Input 80-250VAC Output 24-380VAC

Relay is normally open.  Supply 80-250VAC on the input side allowing the output side to close handling 24-380VAC.
