DIN48 SIZE ANALOG STAR()-DELTA () TIMERS

UL/C-UL , CE , Lloyd Approved

Share this

1.Select four types of time ranges between 0.2 s and 100 s on a single unit.

2.Select between five types of time ranges between 0.04 s and 0.7 s for the switching times.

3.There is a  switching indicator so you can check the operation at a glance.

4.The AC free power supply and shorter body make it easier to use.

5.Compliant with UL, CSA, CE and LLOYD
