5.0 Adjustment Facilities
The following parameters can be adjusted on the unit:-
Umax - Maximum Output Voltage Umin - Minimum Output Voltage
Imax - Maximum Output Current Imin - Minimum Output Current
P - Characteristic of the Voltage Regulator P - Characteristic of the Current Regulator
Ramp up time Ramp down time
The trimmers are adjustable through the front panel.
6.0 Adjustment Instructions
Preparatory Steps
Connect unit according to connection
drawing, disconnect the enable and
adjust set point to zero. The unit will
now operate with the basic factory
settings: output current = rated current,
output voltage = rated input voltage1), Umin = 0,
phase angle control, regulation mode.
The setpoint control curve can be determined by
using trimmers Umin/Umax and Imin/Imax ie the
setpoint control range. At this stage, it is also
possible, to make permanent adjustments,
without external setpoints.
The range minimum always extends from zero to
the adjusted range maximum. The maximum
value must be set first.
Adjustment of the MAX - Values
Umax
Hint: If the output voltage is to be regulated at the maximum set point, then the maximum output
voltage must be limited at a value which reduces the regulation range.
Switch on the mains voltage and enable the unit. Set the current set point to maximum. Now increase
the voltage set point until the required output voltage level is reached (observe current limit indicator).
If the set point source is not yet at maximum, then the output voltage must be reduced again by using
trimmer Umax and then the voltage set point can be further increased until the maximum value of the
voltage set point is achieved. If there is no risk of damaging the load with an over voltage then the
output voltage can be set by using trimmer Umax with the set point turned fully up. Anticlockwise
adjustment increases the output voltage.
Imax
Remove the unit enable. Adjust voltage set point to maximum and current setpoint to zero. Turn
trimmer Imax fully clockwise (10 turn pot). Next enable the unit and adjust the current setpoint to
maximum. Set the maximum current value by turning trimmer Imax anti-clockwise.
