Product information

Description

The Relpol RSR95-500D50-DC is a high-performance solid state relay engineered for demanding DC switching applications. This semiconductor device provides a reliable solution for controlling high-voltage DC loads with precision, utilizing a wide control voltage range to ensure compatibility with various industrial control systems. By eliminating mechanical contacts, this relay offers a significantly longer operational lifespan and silent, spark-free switching compared to traditional electromechanical relays.

Advantages

The primary benefit of this solid state relay is its ability to handle high-current DC loads up to 50A with exceptional reliability. Because it operates without moving parts, it is immune to contact wear, bouncing, and environmental contamination, making it ideal for high-frequency switching tasks. The device features a fast response time and high isolation between the control and load circuits, ensuring safe and efficient operation in complex electrical environments.

Suitable for

Industrial automation systems
Heating element control
DC motor switching and speed regulation
Power supply management
Lighting control systems

When it may not be suitable

This relay is specifically designed for DC-to-DC switching applications and is not compatible with AC load circuits. It may also not be suitable for applications requiring extremely high switching frequencies that exceed the thermal dissipation capabilities of the device without proper additional cooling.

Key specifications

Control voltage range: 4-32V DC
Load voltage range: 3-500V DC
Maximum load current: 50A
Switching technology: Semiconductor (Solid State)
Operational life: High durability due to no mechanical wear

How to use

To install the relay, connect the control signal wires to the input terminals, ensuring the polarity is observed according to the 4-32V DC range. The load circuit should be connected in series with the load and the DC power source across the output terminals. It is essential to mount the relay on a suitable heat sink to dissipate heat generated during operation, especially when switching currents near the 50A limit.

What to consider before purchase

Verify that your load voltage does not exceed 500V DC.
Ensure your control signal source provides a stable voltage within the 4-32V DC range.
Assess the need for an external heat sink based on your specific load current and ambient temperature.
Confirm that the application requires DC switching only.

Usage recommendations

Always ensure that the relay is mounted on a thermally conductive surface or heat sink to maintain optimal performance and prevent overheating during continuous high-current operation.
