Dear sir,
I would have using Digital timer for my Outside lights ( FRONTIER DIGITAL TIMER TM619H). In the normal Electricity( 220VAC 50 HZ) from the Government supply ( KSEB) it works, and I am satisfied. But if the Power supply fails, My inverter generated supply ( Not Pure sine wave [ old model] ) substitute the power, but the Timer starts to generate hea SEVERELYt.
Now I installed one timer to my Aunt's house, there is also the same problem arised and blasted the Timer.
I dismandled the item and found some information that described below.
The Power Supply section of the timer using a Resistor Capacitor Diode combination. The said Capacitor was Blasted.
The rating of the
Capacitor - 474K 300V.
Resistor - 19K ohms 2 NOS
Diode - 1N 4004.
Can you help me in this issue to modifiy and reinstall the Circuit. The Out put is throgh a relay ( model: TR90-48VDC-SC-A4 R)
