NOTES:

1. Connections: For output terminals, the wire cross sections must be

adapted to the load current and to the overcurrent protection device

characteristics. The relay rated voltage must be adapted to the mains

rated voltage. These relays use screw clamp connections.

2. Mounting: Should be in the vertical

position. Protect heat-sensitive

materials as well as people from contact

with the heat sink. For non-vertical

mounting, the load current must be 50%

derated. The SSR needs air convection

through the heat sink. Lack of air

convection produces abnormal heating.

Keep a distance between the upper

SSR and the lower SSR (see figure on

the right). In case of zero space

between two SSRs, reduce the load

current. It’s suggested to keep the heat

sink temperature under 90°C. Forced

cooling significantly improves the

thermal performance.

3. Typical application loads: The DRD

relay is designed for resistive and motor loads. For other loads, check

the inrush current at turn-ON and possible

overvoltages at turn-OFF or contact factory.

4. Protection: To protect the SSR against a

5. EMC:

Immunity: lmmunity levels of the DRD comply

with EN61000-4-4 & 5.

Emission: The system integrator must ensure

that systems containing SSRs comply with

the requirements of any rules and regulations

applicable at the system level. The very low

zero-cross voltage (<20V) improves the

conducted emission level in comparison with

most SSRs with zero-cross voltage higher

than 50V.

6. All electrical parameters specified at 25°C

unless otherwise noted.
