438UPS

The 438UPS is a Solid State Timing Device that performs as an in-line delay on-make timer. By connecting the two terminals in series with any load circuit drawing between ten milliamperes and one ampere operating from 19V and 288VAC or DC, the 438UPS turns that load circuit into a delay-on-make timing circuit. The timing period is set by an internal potentiometer from one second to six minutes. After the load circuit has energized a new cycle can be repeated by removing and reapplying the operating voltage. The internal potentiometer controls the timing period from 1 to 480 seconds. Timing is essentially linear between 1 and 480 seconds permitting the potentiometer to approximate the value of timing over its adjustment span of 270° to within 10% of the desired timing period.
