OUTPUT SPECIFICATIONS

Voltage/Current Levels

PLH120 - 0 to 120V / 0.01mA to 750mA (90W max.)
PLH250 - 0 to 250V / 0.01mA to 375mA (94W max.)
Note: Actual maxima for voltage and current are typically 1% greater than the figures given above
except for the voltage control on the PLH250 which is limited to 250.0V.

Output Setting & Control

Voltage Setting: By coarse and fine controls.
Current Setting: By single logarithmic control.
Low Current Range: Reduces max. current to 75mA and increases resolution to 0.01mA.

Output Mode: Constant voltage or constant current with automatic cross-over.
CC indicator lit in constant current mode.

Output Switch: Electronic, non isolating. Preset voltage and current limit displayed when Output is off.
Output rise time no load <20ms.

View Settings: With the output On, the meters show actual voltage and current.
The preset levels can be viewed and adjusted at any time by pressing the View Settings button.

V-Span (Voltage Span Control)

The voltage adjustment range can be controlled by digital setting of the end-stop values of
the coarse voltage control to any desired values. The range for Vmax is 1V to 120V or 250V depending on
