Heavy duty delay off countdown timer

Heavy duty timer unit, which turns the power off after a pre-set adjustable time (0.1 seconds to 10 days) from the button being pressed. Applications include numerous uses to save energy such as industrial machinery, hay steamers and forklift truck chargers. If the time interval required is entered at the checkout, we will supply it already set. The time can also be user adjusted by removing the cover of the enclosure and turning a dial.

Operation:

• The timer is triggered by pressing the button
• Once triggered, the unit switches the power on and the light illuminates.
• The power turns off at the end of the pre-set time.
• The button can then be touched again to turn the power on and restart the cycle. Pressing the button during the countdown cycle will restart the countdown timer. 

Our timers are the only ones on the market which use an industrial contactor instead of a relay to switch the load. Other units use a relay, which is a cheap, compact way of controlling resistive loads. The issue is that machinery with a motor creates an inductive load (further explanation of load types can be found here). When the relay contacts open to turn the tool off, the stored inductive energy in the motor coil is discharged, resulting in a damaging arc across the terminals, which can eventually cause the relay to fail. We use a high quality contactor instead of a relay. Contactors work using the same principle, but they are much larger and far better suited to switching higher current inductive loads. The picture below shows the sheer size difference between a typical contactor (left) and relay (right); when it comes to switching inductive loads, contact size really does make a difference.
