Pin Assignment Below are the pin assignments of the analog interface. Figure 3.
Emergency Shut Off In the case where an emergency shut off to the output of the power supply is required, SHUT_OFF (pin 15) and DGND (pin 1) is used. To shut off, connect/short Pin 15 and Pin 1 together. This will bypass the analog control of the output state and disable (OFF) the output. In this case, pin 14 and pin 1 will need to be disconnected/opened from each other and reconnected to enable output again.
Reference Voltage A 10 VDC reference output is available on REF_10V (pin 21) and Ground (pin 9). Note: These pins are used for reference only and are not designed to power devices. Do not connect a load across it. Configure Voltage Limit The minimum and maximum set voltage can be configured on the power supply to limit the settable voltage range for protection.
Parallel/Series Connection More than one unit of the same model can be connected in a parallel or series configuration. Table 3.2 below shows the total number of units that can be connected in each configuration. The power supplies can be set up in master/slave mode so that the master unit can control all other power supplies in the parallel or series connection.
For parallel connection: Connect each power supplies’ positive (+) terminals together. Do the same for the negative (-) terminals. For series connection: Connect one power supply’s positive (+) terminal to the negative (-) terminal of another. Do the same for all the power supplies. Then, connect all of the power supplies’ Pin 1 of the RS-485 interface together. Do the same for Pin 5. Below illustrates the connection diagram for parallel connection.
