Signal Connector Pin Description Purpose of running multiple modules in parallel is to get higher power. The maximum number of parallel modules is 6, see wiring diagram below. Number of modules Max. Power 1 [kVA] Full coolant temp. range Max. Power 2 [kVA] Reduced coolant temp range to 50°C 2 11.2 12 3 16.8 18 4 22.4 24 5 28.0 30 6 33.6 36 During parallel operation load current is shared evenly between modules. However because of production tolerance on the output voltage calibration and passive current sharing between modules (droop sharing) there may be a deviation of load current - up to 6% difference module to module is possible vs. the average value. The result of this deviation may cause some modules to delive r more current than others. In the Table above, in the centre column (Max. power 1), is the available power when none of the paralleled modules override their nominal current of 25 A. The right column specifies condition for n modules - n * 6 kVA. In the case of Max. Power 2, some of the modules may be operating over their nominal power. Functioning above the maximum power is however acceptable since the overcurrent protection only activates at an output current of ~27.5 A, however this is only possible when operating at a lower coolant temperature range, so that the over-temperature protection doesn’t trip off the overloaded module. Modules connected in a 3 phase configuration, per the diagram below are able to produce a 3 x 400 VAC output. To achieve the 240 VAC, each modules L1 is connected to L2. The slaves function at 120° and 240° out of phase from the master by setting up the addressing per the table below. Note: Eac h of the address pins are digital and have internal pull up impedances, therefore a non-connected pin will result in a logic high.

tech.support@psbel.com MULTI-UNIT CAN ADDRESSING After input power is connected parallel modules (or units connected in a three phase configuration, here after called “paired” units) automatically allocate their addresses on the CAN line. The design allows up to 6 paired modules, addresses are always chosen from the range of B4 to B9. Every time the input power is re-cycled there may be different addresses allocated to units in comparison to the previous state, but they will be always inside of range of B4 to B9. If the user counts active devices, within this range, you know how many modules are actively connected. In case the CAN line is not required for paired modules, then it does not need to be connected. However in the case CAN is not used the sync BUS and chain circuit still need to be co connected. ENABLE CONTROL Output enable control works either through the hardware enable pin or by sending CAN message “nv_b_cmd_Enable”. In parallel mode, hardware enable pins are required to be wired together, this ensures the same level is sent to all modules. The requirement CAN enable message is sent out to all active units. With the exception of the above, both enable controls are equivalent. By re- cycling the enable control (disable then re-enable) will clear an output latch condition that might have occurred because of a protection feature e.g.: output over current, over temperature, etc. PAIRED MODE SYNC Modules use the “sync” signal to synchronize their outputs. This happens automatically and there is no user intervention required. After start up one of the paired units automatically establishes itself as the master, all other units in the paired configuration will default to slave operation. Slaves synchronize their outputs according to the reference waveform from master. READ BACK OF INPUT / OUTPUT VALUES In paired mode each module provides its own values. However in paired mode when input and/or output voltages are tied together there could be a read back inaccuracy of up to typical ± 2V. Regarding output current, each module will provide its own value. To get the total output current the user must summarize read backs from all active modules. PAIRED MODE PROTECTION FUNCTIONS In paired mode, the signal connector wiring is continuously monitored. This monitoring serves to protect modules against losi ng synchronization signal during service and is established via a chain circuit starting from the first module and ending with the last. The user needs to establish the chain circuit in the external wiring harness according to diagrams below. In case the chain line is broken all units in the chain will shut down and provide active warning bit on CAN Bit 29 – Inv_b_flt_SyncError. This may happen for example when signal connector of any unit is unplugged during service. There is no redundancy provided for paired modules. This means in case a functional failure would occur in any of the paired modules, all modules would shut down. This is a requirement to protect output stages of modules against permanent damage. PAIRED MODE CHASSIS GROUNDING During parallel operation it is required that the chassis of all paired modules are galvanic tied together and grounded to PE.
