5.9.9 Advanced Parallel system identification (*idn?)
To identify a system connected in parallel, master unit updates its identification name. Standard
unit identification string format is: TDK-LAMBDA,Gx-y,S/N,G:r.
•
x – rated voltage, y – rated current, S/N – serial number, r – firmware revision.
Parallel system identification string format: TDK-LAMBDA,GSx-z,S/N,G:r.
•
z – total advanced parallel system current.
The “S” letter, following the “G” letter, identifies advanced parallel system.
The total current of the system is updated, identifying the total current. The serial number of the
master unit is preserved.
NOTE
In case of a Blank Panel Option power supply, the additional paralleling system ‘S’ letter is added
following the ‘B’ letter, i.e. TDK-LAMBDA,GBSx-z,S/N,G:r.
5.9.10 Advanced Parallel memory settings
Power supplies change role when assembled (or disassembled) into (from) an Advanced Parallel
System. Three roles are available:
Single – No Slave or Master units are connected.
Master – At least one Slave unit is connected.
Slave – A unit (or multiple units) connected to a Master unit.
Prior assembling an Advanced Parallel System, each units’ role is Single.
NOTE
Memory settings tables are the settings of the power supply immediately following role change.
These settings can be modified by the user in Single or Master roles only. Slave role settings can’t
be modified.
5.9.10.1 Single or Master roles non-volatile memory parameters
Refer to Table 5-3: Single or Master Roles Non-Volatile Memory Parameters for the default non-
volatile memory parameters set when power supply changes its role to Single or Master.

Over Voltage Protection (OVP) [V]
1.1 * RATED or 1.2 * RATED (Model Dependent)
Under Voltage Level (UVL) [V]
