Output
Voltage Output 10kW 20kW 30kW Noise (pk-pk)*** Noise (RMS)***
40Vdc 250A 500A 750A 150mV 40mV
60Vdc 167A 334A 501A 150mV 40mV
(*) Measured at the load terminals, with 1uF in parallel and 6ft of low-inductance load cable with supply operating at full load and nominal input line voltage.
(**) RMS noise is measured directly across the output terminal with supply operating at full load and nominal input line voltage.
(***) Value is for 30kW, single voltage models. Other variations may increase value by 2x.
Sense To compensate load cables voltage drop, units can generate 2% additional voltage at full scale of output voltage.

Output
Output Float Units maybe put in series with the float limit of output terminals must be within ±150V of chassis potential
Parallel Multiple units can be paralleled to form higher power systems. Chassis control loops are tied together so that resulting higher
power systems have the same transient response as a 30kW system. Control commands are only required to be sent to “master”
supply. Parallel supplies require a shielded CAT 5 cable (STP) and appropriate output wiring connections by the user.
Calibration End user calibration is supported. All standard and digital calibration can be performed without removing covers.
Digital Control (Optional) Ethernet (Modbus-TCP or Ethernet/IP), RS-485 (MODBUS-RTU)
Analog Control All control signals are isolated from the outputs
