PRT-CTRL-SE Protege SE Integrated System Controller Installation Manual | June 2017 39
13.2 Current and Validation Example 2
The example shown below refers to the specifications needed to help ensure the correct installation of the
Protege Controller. Specifications have to be validated to ensure that individual maximum currents and total
combined current are not exceeded.
Using a 80VA Transformer
External Devices Connected to Panel
2 x PRX-NPROX Nano Prox Card Readers (120mA @ 13.8VDC) connected on AUX2 Outputs
2 x Electric Locking Devices (520mA @ 13.8VDC)
Current Consumption
Total Combined Current Available 2.5A (2500mA)
Operating Current 120mA (Typical)
Battery Charging 700mA (High Current Charging)
DC Output (AUX2) PRX-NPROX Nano Prox Card Reader (120mA @ 13.8VDC)
DC Output (AUX2) PRX-NPROX Nano Prox Card Reader (120mA @ 13.8VDC)
B1 Output Electric Locking Device (520mA @ 13.8VDC)
B2 Output Electric Locking Device (520mA @ 13.8VDC)
Total Consumption 2.1A (2100mA)
Validation
Is the total DC Output (AUX2) current less or equal to 1.0A (1000mA)? Yes, it is 240mA
Is B1 current output less or equal to 1.1A (1100mA)? Yes, it is 520mA
Is B2 current output less or equal to 1.1A (1100mA)? Yes, it is 520mA
Is the total combined current less or equal to 2.5A (2500mA)? Yes, it is 2.1A (2100mA)
