PEL-3000(H) User Manual

Use resistors with minimum residual resistance of
50Ω or less.
Note for proportional control: Do not use swtiches
that switch between fixed resistances. Please use
continuously variable resistors.
External Resistance Control – Operation
External resistance control can be used to control
the current, voltage, resistance and power for CC,
CR, CV and CP modes. Configuration for each
operating mode is the same.
Proportional Control:
Input current = rated current × (external
resistance/10).
Inverse Control:
Input current = rated current × (1 - external
resistance/10).
