How does the trigger function work on the GENESYS+™?

The GENESYS+™ series of programmable power supplies features new trigger functions to allow the user to initiate either single or multiple actions or send a signal to indicate that an action has been completed. Two trigger signals are available; Trigger In and Trigger Out. These signals can be used to synchronise the GENESYS+™ with other equipment in the system or with another programmable power supply. This function can be used in Constant Voltage or Constant Current mode.

Upon receipt of a Trigger In signal, the output will turn on and start any pre-programmed sequence. A delayed start parameter can be programmed from 0 to 10 seconds. A trigger can be generated from the communication interface by pressing the output current adjustment encoder or by an analogue signal. A Trigger Out signal can be generated when the output status changes, when the programmed output voltage or current changes, or when a pre-set program sequence is completed. In “Function Strobe” mode, a trigger pulse is generated at every step in the program.

Example 1, Fixed Mode: The GENESYS+™ output voltage is initially set to 5V, and is programmed to rise to 10V, 10ms after receipt of a Trigger In signal. The Trigger Out signal is sent when the output voltage programming instruction occurs.

Example 2, Wave Mode (Strobe): The GENESYS+™ output voltage is initially set to 0V, and is programmed to rise to 5V, 100ms after receipt of a Trigger In signal, then rising gradually to 10V over 300ms. After 100ms, the output is programmed to decrease linearly to 0V over 100ms. The Trigger Out signal is programmed to be sent when any output programming voltage instruction occurs and when the sequence has finished.
