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: C***tant voltage or c***tant current with automatic cross-over. CC indicator lit in c***tant 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 model. The range for Vmin is 0 to (Vmax – 1V). S-Lock (Settings Lock) Voltage and current settings can be locked by a single button press. Lock accuracy is equal to the meter accuracy (see Meter Specification). Output Performance Ripple & Noise: Normal mode voltage: <2mV rms and 10mV p-p Normal mode current: <10uA rms ; <1uA rms on 75mA range Common mode current: <20uA rms Load Regulation: Voltage - <0•01% + 10mV. Current - typically 0•01% + 50μA. Line Regulation: Voltage <0•01% + 10mV for 10% line change. Current <0•01% + 50μA. for 10% line change. Transient Resp***e: <250μs to within 50mV of setting for a 90% load change. Temp. Coefficient: Voltage: typically <(50ppm + 2mV)/°C Current: typically <(100ppm + 0.1mA)/°C; <(100ppm + 0.01mA)/°C on 75mA range. Output Protection Output Protection: Output will withstand forward voltages of up to rated output voltage. Reverse protection by diode clamp for currents to 3A. OVP and OCP Trips: Voltage or current measured to be in excess of 105% of the rated maximum will cause the output to trip off. Over-temperature: Output trips off for over-temperature. Safety Interlocks: Operati*** that could cause an unexpected change in voltage or current settings are interlocked with the output switch. Output Connecti*** Output Terminals: Universal 4mm safety binding posts on 19mm (0•75”) spacing. Terminals can accept fixed shroud 4mm plugs, standard 4mm plugs, fork terminals and bare wires. Remote Sense Sense Selection: Voltage sensing is selected as Local or Remote by front panel switch. Sense Terminals: Sprung loaded screw-less terminals.
