Product Description

The CRYDOM Solid State Relay is a panel-mounted, AC-output relay with a Form A (SPST-NO) switch configuration. It accepts an 18-36 VAC input at 10 mA and switches 48 to 530V AC output, with a maximum output current of 12 A without a heat sink. The relay uses a screw-clamp electrical connection and is not finger-safe.

Frequently Asked Questions

What is the CRYDOM HA4825E solid state relay used for?

The CRYDOM HA4825E solid state relay is used for switching AC loads in industrial automation, HVAC, and process control systems. It provides reliable, silent switching without mechanical contacts, making it ideal for high-cycle applications.

What are the specifications of the CRYDOM HA4825E?

The CRYDOM HA4825E is a panel-mounted, AC-output solid state relay with SCR output. It accepts 18-36 VAC input at 10 mA, switches 48 to 530V AC, and has a maximum output current of 25 A (12 A without heat sink). Connection is via screw clamp.

Where to buy the CRYDOM HA4825E worldwide?

You can source the CRYDOM HA4825E solid state relay through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring a smooth procurement process.

How to select a heat sink for the CRYDOM HA4825E?

For the CRYDOM HA4825E, a heat sink is required when output current exceeds 12 A. Select a heat sink rated for the relay's maximum 25 A load and ambient temperature. Proper thermal management ensures reliable operation and extends relay life.

Used in

Common applications for CRYDOM
Industrial heating — Crydom 53TP series SSRs control resistive heating elements in furnaces and ovens, with zero-voltage switching to reduce electrical noise.
Plastics machinery — Dual Crydom SSRs (e.g., CC4850W2V) manage barrel heater bands and mold temperature controllers, providing independent control of multiple zones.
Packaging equipment — Panel-mounted Crydom SSRs switch motors and solenoids in high-speed packaging lines, offering long life and resistance to vibration.
Lighting control — Crydom triac-output SSRs (e.g., 21R940) dim or switch industrial lighting circuits, with finger-safe terminals for operator safety.
HVAC systems — Crydom SSRs regulate compressors and electric heaters in commercial HVAC units, with AC input compatibility for direct control from thermostats.
Water treatment — Crydom SSRs switch pumps and valves in water treatment plants, with SCR output for inductive load control and heat sink options for high ambient temperatures.
