Universal Potentiometer Time Capsule ®

Model No. 438UPS Description:
The model 438UPS (Universal Potentiometer Adjustable Time Capsule) is an all Solid State timer providing Delay on Make control to any load operating from 19 to 288V AC or DC. When power is applied, the 438UPS remains in the off state. When the preset time period has elapsed, the 438UPS switches on allowing the load to energize. The load remains energized as long as power is applied. Power must be removed for at least 50 milliseconds to reset timer.
