- **Low output ripples and spikes** 

- **Suitable for household appliance and industrial application** 

- **For distributed power** 

- **Operating temperature range: –25°C to +70°C** 

- **UL 508 listed** 

- **UL 1310 class II, NEC class 2 compliance** 

- **3-year product warranty** 

UL 508 UL 60950-1 IEC 60335-1 IEC 60950-1 

This new DIN-Rail mounting power supplies are designed for industrial and residential applications. They are lower cost than the existing TBL range, with similar electrical specifications. Additionally, they fully comply to the new standby power and efficiency requirements (ECO Standard). They are intended for connecting as class II devices, so the safety earth connection is not required. They are mountable in flat racks due to their small dimensions in depth. Their dimensions comply to the DIN 43880 standard.
