Cautions while using the SSR |
SSR-120DD 120A 3-32VDC input 5-60VDC output single phase dc to dc ssr solid state relay
When the current is up to 40A,the SSR must be installed with radiator.
The dimension of radiator:

1. Over-current and loading short circuit result in SSR permanent damage. Quick fuse is one of the over-current protection methods. Small capacity may also adopt fuse. Over-voltage protection adopts parallel connection metal oxide varistor (MOV) as well as RC absorbing return inside SSR. The area size of MOV determines the absorbing power. The thickness of MOV determines protective voltage value. Generally, 220V series SSR may choose varistor of 500-630 VDC, 380V series SSR may choose varistor of 700-900VDC.
2. If ambient temperature is too high, the loading capacity of SSR will descend. If the ambient temperature is high or the heat radiation is bad, the chosen SSR should be kept a certain margin.
3. The resistance load should not surpass 60% of rated current. The inductance load should not surpass 40% of rated current.
