Hoefer PS2A200 - Manual (Page 14)

Parameter and operation overview
Parameter options
The PS2A200 can be set within the parameter
options mapped out below. Note that power
parameters are displayed on the top line of the
LCD, and time parameters are displayed on
the bottom. Options are listed in the order they
are encountered.
Power parameters
Because the power limit is 200 W (W = V˙A), the
maximum current of 2000 mA can be delivered
only if voltage is limited to ≤100 V. Conversely,
the maximum voltage of 200 V can be delivered
only if the current is limited to ≤1000 mA.
During a run the location of the cursor indicates
which parameter is being held constant. If load
requirements are such that an unprogrammed
crossover occurs (for instance, instead of holding
voltage constant, as programmed, current is held
constant), the parameter unit (V, mA, or W) will
flash, indicating that this value rather than the
programmed value is being held constant.
