Efficient DC Switching Solutions

The CG SSR solid state relay provides reliable single-phase DC control, operating with a control voltage range of 3-32V DC and supporting load voltages up to 600V DC.

Available in multiple load current ratings from 10A to 200A, it's designed for seamless integration into general-purpose DC load applications.

Durable Construction and Protection

With sealed housing and CE certification, the relay ensures longevity and compliance with safety standards.

Included heat sink and mounting screws facilitate effective heat dissipation to prevent overheating during operation.

Sealed for environmental protection
CE-certified for quality assurance
Heat sink included for thermal management

Choosing the Right Relay and Heat Sink

Select your SSR variant based on the load current required and consider load type ratios: 70% resistive, 20% inductive, 10% capacitive to size properly.

For currents above 60A, adding a cooling fan is advised to maintain optimal operating temperature and prolong relay life.

Determine control mode type (AC/DC) appropriately
Choose appropriate relay current rating based on equipment
Ensure proper heat sink and cooling fan usage

Testing and Usage Notes

Inside, the relay contains semiconductor switches which do not show conduction with standard multimeter tests; testing requires applying an actual load such as an incandescent lamp.

Solar loads are mixed and may cause relay malfunction; use with tenfold current capacity if attempting in solar applications.

Semiconductor relay requires load for switching tests
Not recommended for direct solar equipment loads without oversizing

Product FAQ

Frequently asked questions

01 What input control voltage does the CG SSR support?

It supports a control voltage from 3 to 32 VDC.

02 What is the voltage range for the load?

The relays support load voltages from 5 to 220 VDC or 5 to 600 VDC depending on the model.

03 What load currents are available for these SSRs?

They are available in 10A, 25A, 40A, 60A, 80A, 100A, 120A, 150A, and 200A ratings.

04 Is a heat sink included with the relay?

Yes, a heat sink is included along with two screws for installation.

05 Is this CG SSR suitable for solar equipment?

Solar equipment is considered a mixed load and is not recommended for use with these SSRs unless the SSR has at least 10 times the load current rating.

06 What protection features does the relay have?

The relay is sealed to protect the internal semiconductor components.

07 Does the SSR have any certification?

Yes, it is CE certified.

08 Can I test the relay with a multimeter?

Using a multimeter diode or resistor test will show a high-impedance state; the proper test is with a load such as an incandescent lamp to confirm switching.

09 Is the relay suitable for inductive or capacitive loads?

The SSR ratio recommendations are 70% for resistive loads, 20% for inductive loads, and 10% for capacitive loads.

10 Are cooling fans required with these SSRs?

If the current exceeds 60A, a cooling fan is recommended to extend the relay's life.
