Default Re: UPS in a wooden cupboard

Hi , The NISSEI DPS300GL 30A 13.8 psu uses this neat little circuit. All non critical except the thermistor which you will have to experiment with a variable resistor first before choosing a part unless spares are availiable for these things.

The thermistor is on the heat sink though which gives it quite a temperature range to work with.
