(*) 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.

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
|
Advanced Digital Features (Requires Optional Digital Control)
|
Graphical User Interface
