RE: Mains Voltage Halogen & LD11

[Mike Griffiths <mike@xxxxxxx>]

Thanks Both Keith and Ian
LD11 now back working
For those interested in RS Part #
Triac RS# 659-995 =A31.13 each
Quick-Acting (F), HBC, 216 Series Fuses RS# 388-6526 =A31.20 for 10

I don't know if these fuses are quick enough but time will tell

It was an fiddly job to change the Triac but worth it

I also got=20
Relay, base, DIN rail/surface, 10A, SPCO

&
Relay, SPCO, LED, test button, diode, 12Vdc
=A37.89 for both=20
I'm going to play with them if you can hard wire these DIN mounted relays
work out a lot cheaper than AD10

all prices ex VAT
I'll keep you informed on progress
Mike

The triac will be short circuit. Replacing that will restore proper
operation.

The problem is the fuses dont blow quick enought to protect the triac.

You need a hispeed ceramic fuse to protect the triac properly.

these are 20mm fuses which will not fit the fuseholder on the LD11. You
could fit one in an external holder in series with the output of the LD11.
That should give greater protection.
