Fibaro FGS-213 relay stick 5000w


MDC

Recommended Posts

Hello,

After I read on this forum seems some Fibaro module really got stick on some led driver and other device that has electronic inside other than resistive loads.  I not find any information that show if this happen to old models of modules only or also happen to new models.

 

Since new Fibaro FGS-213 module can handle only 8A ~ 230v = 1840w and only resistive loads, and I plan to use module in a DIN rail enclosure and power a contactor 16A to power in this way my electric oven that has 2500w, and other device that need more than 4500-5000w.

I connect my oven direct to Fibaro module and I've got overcurrent notification each time.

 

Anybody use Fibaro modules to increse power whit a contractor 16A or 20A with 220v coil? This will damage Fibaro module really? 

 

I found other solution to use Fibaro FGS-213 with solid state relay, but in this case are some problems: 

  1. Heat (SSR relay at 20A become hot) and in a DIN rail enclosure....is not ok. Imagine you have 10 circuits.
  2. LED lamps glowing when off or even flick (is a fix by adding a normal light bulb in parallel of leds)

I'm one of the topic starters on that "sticking issue". Just use another electro-mechanical (din) rail relay (or contactor) between the module and the load. The FGS-2x3 module drives a 230 V coil, but not a 12 or 24 coil! You won't be able to use energy monitoring. As you found out, the FGS is not rated for your load and a solid state relay is not ideal. To get rid of the heat, the SSR would need a really big heatsink, making it at least as big as a contactor. But it would be silent. Note that you have to derate an SSR for non-resistive loads, if I really wanted one, I'd go with 40A. Wait, the coil of your contactor also produces some heat, it's in the data sheet! I cannot give you a reference to such a big relay, the largest ones in my collection are 20 A, for PCB mount. They are about the size of a fibaro module, so expect something big for 40 - 60 A. If you want help with a data sheet, post it and I'll have a look. Does this help?
