Product Description

The CRYDOM HD4850 is a panel-mounted solid-state relay with a screw-clamp electrical connection, providing an AC output across a voltage range of 48 to 530V AC. It features a Form A switch configuration, an input current of 12 mA, and a maximum output current without a heat sink of 12 A. This surface-mounted relay is not finger-safe and is designed for AC current applications.

Frequently Asked Questions

What is the CRYDOM HD4850 solid state relay used for?

The CRYDOM HD4850 is a panel-mounted solid state relay used for switching AC loads in industrial automation, HVAC, and process control systems. It handles output voltages from 48 to 530V AC and up to 50 A with proper heat sinking, making it suitable for resistive and inductive AC loads.

What are the specifications of the CRYDOM HD4850?

The CRYDOM HD4850 is an AC-output solid state relay with a Form A switch configuration, 12 mA input current, and screw clamp electrical connection. Maximum output current without heat sink is 12 A; output voltage range is 48 to 530V AC. It is panel mounted and not finger safe.

Where to buy the CRYDOM HD4850 worldwide?

You can source the CRYDOM HD4850 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine CRYDOM components for industrial applications.

How to select a heat sink for the CRYDOM HD4850?

For the CRYDOM HD4850, select a heat sink based on your load current and ambient temperature. Without a heat sink, maximum output current is 12 A. For currents above 12 A up to 50 A, use a properly rated heat sink to maintain junction temperature within limits. Consult CRYDOM application notes for sizing.
