DPS-15 Dual Power Supply – Current Calculation
The DPS-15 power supply has two independent linear 1.2 Amp DC outputs – the ACU supply and the AUX RDR
supply. Use the following two tables for calculating the total current required from the ACU supply and the AUX
RDR supply. Please note the ACU supply and the AUX RDR supply each have an operational limit of 1000 mA.
ACU Supply – 1.2 A
Opposite Add-on Board #, enter the name of the module in the Product Description column and the board's
current requirement in the Current Rating column. Current ratings are in the preceding table and printed on
the circuit boards. Add all the current ratings including the control board to determine the total current.
Keyscan recommends a 200 mA reserve operating margin. The total current from the ACU supply, including
the control board, should not exceed 1000 mA.
