(Left graph) Note that it is necessary to reduce the load current as the ambient temperature of the SSR may increase due to operating conditions. (Figure below is an example of the G3M-205P(L) model) When using the SSR, design the system to allow heat dissipation sufficient to stay below the Load Current vs. Ambient Temperature characteristic curve. **==> picture [188 x 247] intentionally omitted <==** **----- Start of picture text -----**<br> <Z direction><br>6<br>5<br>4<br>G<br>3 3<br>2.5A L=20.37�� M<br>2 1.8A L=12.7��<br>1 0.8A L=7.62��<br>0<br>−30 −20 0 20 25 40 60 80 100<br>Ambient temperature (°C)<br>L L<br>Top 10 pcs.<br>Bottom<br>Load current (A)<br>**----- End of picture text -----**<br> - Thirty Relays are soldered to the PCB at each given spacing. - Continuous power. **3** G3M **Solid State Relays** **==> picture [13 x 115] intentionally omitted <==** **----- Start of picture text -----**<br> G<br>3<br>M<br>**----- End of picture text -----**<br> ## ■ **Dimensions** (Unit: mm) **==> picture [512 x 363] intentionally omitted <==** **----- Start of picture text -----**<br> G3M-203P(L) PCB Dimensions (BOTTOM VIEW)<br>G3M-203P(L)<br>G3M-203P(L)-4<br>2.54 Four, 1.2 dia. holes<br>Terminal Arrangement<br>2.54 (BOTTOM VIEW)<br>4 0 max . 9 max.
