Particularly, the range will find favour with designers and manufacturers of control systems for building services, heating and ventilation, water and sewage treatment, motor starting and automatic machinery.
Exhibiting versatility, the star delta timer will operate on supplies ranging from 12 to 240V AC or DC and the true off delay from 24 to 240V AC or DC. So one model for all voltages minimises stock holding, simultaneously maximising plant availability due to the lower spares requirement. Further, the timers feature multiple time ranges, so again, stock holding is minimised.
All of the 80 series timers from Finder are a slim, space saving 17.5mm width, and for ease of installation and servicing clip onto standard 35mm rail. When fitted side by side, 80 series models bring a neat, uniform appearance to the control panel.
The 80.82 star-delta timer features both adjustable run up and transfer time settings for optimum star to delta changeover efficiency and performance.
The output contact has a rated current capacity of 6A with a maximum peak current of 10A and a rated switching voltage of 250VAC, and 400VAC maximum. Selectable timing ranges for the 80.82 span 0.1 seconds to 20 minutes.
Providing a ‘true off’ timing capability, the 80.61 timer has an 8A rated changeover contact (single pole, double throw), whilst four timing ranges spanning 0.1 seconds to 2 minutes are all available from one timer. As a true off timer, the unit commences timing upon removal of the supply. Other timers may need the power to be maintained in order to function.
All of the 80 series timers from Finder feature programmable microelectronics married to a reliable and robust electromechanical relay output user interface. Further, Finder’s total in-house design and manufacture cover all aspects of the electronics, electromechanical and mechanical elements of the products.
