Table 4: Register Scaling Factors - Ideal Power Stabiliti Series Quick Start Manual

the Converter within the 16-bit range of 0-65535 for unsigned and -32768 to 32767 for signed
values.
These scaling factors apply to read only "measurement registers", as well as read/write "setpoint
registers" used to set desired output voltage, current, or power levels. The setpoint registers are
generally not utilized in 30C stand-alone applications.

In 30C3 applications, a DC power command of +1500 on DC3 will deliver 15 kW of "export
power" (charging a battery). Conversely, a DC power command of -1000 on DC3 will deliver 10
kW of "import power" (discharging a battery).
The ramp rate command is a modifier of the power command defined above. It limits the port
ramp rate (power, current, or voltage depending on selected Control Method). A power ramp
rate setting of 300 limits the ramp up or ramp down of the commanded port to a 3 kW/second
rate.
