We've used Optoblocks (SSR's) for years in traffic signal work, very reliable. Max Balchowsky SEE systems From: Marv Dargatz To: RE-wrenches Sent: Wednesday, April 29, 2009 10:33:51 AM Subject: Re: [RE-wrenches] Solid state relay (SSR) quest

Re: [RE-wrenches] Solid state relay (SSR) questions

Hey Mick, We used a lot of SSRs in wind turbine controls.  Found them to be extremely reliable.  Overrating the device is a very good idea.  Also be careful of very low temperatures, as the Current Transfer Ratio (CTR) of the optical isolation can degrade over time and eventually cause failure

Hello, Wrenchers and special greetings to the silicon gurus to whom I address these questions about solid state relays. A client wants a gizmo to connect grid "AC In" to their inverter/charger when the battery voltage is low...resembling the LBX function on the good ol' Trace SW inverter. The grid
