500  V_{DC} 
Neutral Current Limitation
As the OP8110 neutral point for each group is formed by the midpoint of two capacitors across the DC input rails, there are frequencydependent limits on the maximum current that can flow through the neutral point terminals. This current limitation applies primarily for lowfrequencies; above 25Hz the maximum output current of the amplifier (14A_{RMS}) can flow through the neutral point, while for lower frequencies the maximum neutral current is reduced.
Please note, this lowfrequency neutral current limitation is primarily applicable to amplifier configurations that induce large neutral currents, such as singlephase and unbalanced threephase operation.
The following figure outlines the maximum neutral current (total current of all three neutral terminals within an OP8110 group) vs AC frequency for the OP8110*:
*NOTE: To attain the maximum neutral current specified in the above graph, the 3 neutral terminals of the respective OP8110 group (located at the rear of the OP8110 unit) should be connected together

Timing Specifications
The following timing parameters must be considered for the system functionality/stability:
t_{COM_SET} = Propagation Delay of the setpoint: V and/or I, typically around 10ns (negligible)
t_{OP8110} = Intrinsic Delay of the OP8110
t_{COM_MES} = Propagation delay of the measurements: V and/or I, typically around 10ns (negligible)
t_{RTS }= Time required by the realtime simulator to compute and output a setpoint
≈ 10 to 50µs on CPU (ex: OP4512)
≤1µs on FPGA (eFPGASim)
t_{d} = t_{RTS }+ t_{COM_SET }+ t_{OP8110 }+ t_{COM_MES}
Where td is the total time delay of the closed loop, introduced by the power amplifier, measurement, and discretetime nature of realtime simulator.
The OP8110 provides the following timing characteristics:
