Description and Introduction

High Voltage Solid State Relays The part **LH1504** is a **solid-state relay (SSR)** manufactured by **Crydom (now part of Sensata Technologies)**.

### **Specifications:**  
- **Input Voltage (Control Signal):** 3–32V DC  
- **Output Voltage (Load Side):** 24–280V AC  
- **Load Current:** 3A (continuous)  
- **Switching Type:** Zero-crossing (for AC loads)  
- **Isolation Voltage:** 4,000V RMS  
- **Mounting Type:** PCB or DIN rail mount (depending on variant)  
- **Operating Temperature:** -30°C to +80°C  

### **Description:**  
The **LH1504** is a **single-pole, normally open (NO) SSR** designed for switching AC loads. It provides **electrical isolation** between the control circuit and the load, reducing noise and improving safety.  

### **Features:**  
- **Zero-crossing switching** for reduced EMI and inrush current  
- **LED indicator** for input status  
- **High reliability** with no moving parts  
- **Compact design** for space-saving installations  
- **RoHS compliant**  

This relay is commonly used in **industrial automation, HVAC systems, and lighting control** applications.  

(Note: Always verify the exact datasheet for your specific model, as variants may exist.)
