Checking the Controller’s Current Limit Point after Adding or Removing a Rectifier, -48 VDC to +24 VDC
Converter Module, or -48 VDC to -58 VDC Converter Module
If a rectifier, -48 VDC to +24 VDC converter module, or -48 VDC to -58 VDC converter module is added; the respective current limit
point in amps will automatically increase to maintain the same percentage. For example, if the current limit was set to 100% of
combined capacity and a module is added, the new current limit setpoint will be 100% of the combined capacity including the new
module.
