Output Current Limitation Note

There is a low-frequency current limit including 10Arms at 50Hz and 12Arms at 60Hz. The limit will be 14Arms at 70Hz and above.
Large output currents are not reduced in all modes of operation but only in single-phase and three-phase-unbalanced modes.

Timing specifications

The following timing parameters must be observed to provide the required global Real-Time Simulator functionality/stability:

t_{COM_SET} = Propagation Delay of the set-point: V and/or I, typically around 10ns (negligeable)

t_OP8110 = intrinsic Delay of the OP8110

t_{COM_MES} = propagation delay of the measurements: V and/or I, typically around 10ns (negligeable)

t_RTS= Time required by the Real Time Simulator to compute and output a set-point

≈ 10 to 50µs on CPU (ex: OP4510)
≤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 discrete-time nature of real-time simulator.
