Relay info
I'm replacing a relay in a power supply and the relay is marked ITT STJ 70 47d. Coil voltage seems to measure 60v.
I want to change it for a relay of the same coil voltage but higher rating, say 250v 10 amp. (I have been advised that the current relay is a bit light for the unit which drives my 1154). I also intend to put wire wound resistors in series to limit inrush current. Anyone got any advice on the relay? Will something like this be a suitable replacement? http://docs-europe.electrocomponents...6b80fa75d8.pdf D |

Re: Relay info
I am not familar with that ITT relay.
The replacement relay appears to be OK to me although I would personally check the operating current / resistance (I often use relays for low voltage / current in which the coil resistance becomes more critical). From my experience the resistor for inrush current is more of an issue (ie power rating and heating effects / clearance to other components). |
