Solid state relay, 3 phase, SSR-60DA, 60A 3-32V DC to AC

Features

60A 3-phase solid state relay (SSR) with 3-32V DC input and 24-480V AC output features compact size, high structural strength, good impact resistance, and strong shock resistance. The SSR offers a reliable switching the commercial and industrial loads, such as computer peripheral interface device, printing machine, molding machine, food machine, packaging machine, and so on.

• Built in RC absorption
• Photoelectric isolation
• SCR output
• LED indicator for operation status
• Removable protective cover for safety
• Panel mount
• Zero-crossing switch type

Specification

Note:

1. When the load is a resistive load, the maximum load current of the selected SSR should be 2~3 times greater than the actual load current;
   
2. When the load is an inductive load, the maximum load current of the selected SSR should be more than 7~8 times the actual load current.
   
3. When the maximum load current is higher than 10A, a heat sink must be installed to the solid state relay, or the SSR relay should be mounted on a metal base plate with heat dissipation effect, and the thermal grease is applied between them.

Tips: Ambient temperature for solid state relay

Load capacity of solid state relay is greatly affected by the ambient temperature and its own temperature rise. During installation and use, good heat dissipation should be ensured. The SSR with the rated working current above 10A should be equipped with a heat sink and the SSR above 100A should be a radiator and a fan for forced cooling. In the installation, pay attention to good contact between the bottom of the relay and the radiator, and consider appropriate amount of thermal grease coated in order to achieve the best cooling effect.
If the solid state relay is working at high temperature (40 ℃ ~ 80 ℃) for a long time, the user can consider derating to ensure normal operation according to the maximum output current and ambient temperature curve data provided by the manufacturer.
