" to realize the connections, but it is limited to the series and parallel connections between CH1 and CH2. If users need to connect the UDP3305S series power supply in series and parallel with other power supply channels, they can only realize it through external wiring, as shown in the figure below, but pay attention to the following... -
Page 17: Power Supply Series Connection
Higher voltages can be provided by connecting power supplies in series. In this case, the output voltage is the sum of the output voltages of all the channels. When the UDP3305S series power supply enters the series mode, users only need to set its output voltage, output current, and the overvoltage and overcurrent protection values. - Page 18 High currents can be provided by connecting power supplies in parallel. In this case, the output current is the sum of the output currents of all the channels. When the UDP3305S series power supply enters the parallel mode, users only need to set its output voltage, output current, and the overvoltage and overcurrent protection values.
- Page 19 List Mode (Timer) and Delayer UDP3305S series power supply provides the timer and delayer functions. When the timer is enabled, the instrument outputs the preset parameter groups (at most 2048 groups): voltage, current and timing time.
- Page 20 UDP3305S Series Programmable DC Power Supply User Manual The interface of list mode is as follows: To set the list mode parameters manually: Press “Basic parameter” key to enter the setting interface. Users can edit the starting group number, the required number of output groups (maximum 2048 groups), the number of cycles (maximum 99999 times) and the output status after the timing time expires.
- Page 21 UDP3305S Series Programmable DC Power Supply User Manual Delayer Parameter Setting The interface of delayer is as follows: To set the delayer parameters manually: Press “Basic parameter” key to enter the setting interface. Users can edit the starting group number, the required number of output groups (maximum 2048 groups), the number of cycles (maximum 99999 times), and conditions for terminating the output state and stopping the delayer.
- Page 22 UDP3305S Series Programmable DC Power Supply User Manual The list mode and delayer are equipped with multiple output templates. The purpose is to facilitate users to operate and save time. The following sections describe the parameters of each template. List Mode Templates The optional list mode templates include: sine, pulse, ramp, stair up, stair down, stair up down, exponential rise and exponential fall.
- Page 23 UDP3305S Series Programmable DC Power Supply User Manual 4. Stair Up The Stair Up waveform is as shown in the figure below. The instrument determines the amplitude of the Ramp according to the maximum and minimum currently set. The total number of points (N) will divide the amplitude into N-1 steps.
- Page 24 UDP3305S Series Programmable DC Power Supply User Manual Exponential rise 8. Exponential Fall The Exponential Fall waveform is as shown in the figure below. The instrument determines the amplitude of the waveform according to the maximum (M) and minimum (N) currently set and determines the waveform period according to the total number of points (P) and the time interval (maximum 99999).
