Input Voltage
The dual bus circuit breaker panel can accommodate either –24 Vdc on both buses or –48 Vdc on
both buses.
The voltage level is sensed by the circuit breaker panel circuitry. The input voltages used with
the circuit breaker panel can fall within the following ranges:
• –24 Vdc nominal, within range of –21 Vdc to –30 Vdc
• –48 Vdc nominal, within range of –42 Vdc to –56 Vdc
