(*) 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 |
Advanced Digital Features (Requires Optional Digital Control) |
Graphical User Interface |
Graphical User Interface (Windows based) enables remote control and display of the supply operation including the a dvanced features listed below: |
Oscilloscope Function
