Model AP4830 is useful in controlling process equipment requiring voltage or current ramp control. Typical applications include temperature cycling, PID controller setpoint control, motor control and bumpless control transfer.

The AP4830 provides a DC output that can be programmed to ramp up or down to a setpoint by supplying 0-5VDC to the setpoint Control (pin 6) and the Ramp Rate Control (pin 10) inputs. An external potentiometer, typically 10k Ohms or greater, may be used to attenuate the built-in +5V reference and provide intermediate setpoint and rate values. Use a rotary switch or relay to select multiple potentiometers for different setpoint and rate selections. To 'hold' the output ramp indefinitely, disconnect the setpoint control input (pin 6)
