SPECIFICATIONS
Input Voltage: 90 - 135Vac, ±10%, 50/60 Hertz @ 2 amps 185 - 265Vac, ±10%, 50/60 Hertz @ 1.5 amps Input voltage is switch selectable Output Voltage: See “model selection” table Output Polarity: Positive or negative, specify at time of order Output Current: See “model selection” table Voltage Regulation: Line: ±(0.01% of setting + 0.01% of maximum) for ±10% input line change. Load: ±(0.02% of setting + 0.02% of maximum) for FL-NL and NL-FL change. Current Regulation: Line: ±(0.05% of setting + 0.05% of maximum) for ±10% input line change.rated full current. Load: ±(0.1% of setting + 0.1% of maximum) for 0 to maximum rated output voltage change. Ripple: 0.1% of setting + 0.1% of maximum, peak-to-peak. Temperature Coefficient: Constant voltage operation: ±(50ppm of setting + 50ppm of maximum)/°C Constant current operation: ±(100ppm of setting + 100ppm of maximum)/°C Stability: (1/2 hour warm up) Constant voltage operation: ±(0.01% of setting + 0.01% of maximum)/hr.; ±(0.02% of setting + 0.02% of maximum)/8 hrs. Constant current operation: ±(0.02% of setting + 0.02% of maximum)/hr.; ±(0.04% of setting + 0.04% of maximum)/8 hrs. Internal Controls: Independent precision multi-turn potentiometers for voltage and current control. The resolution of each control is 0.05% of maximum. The potentiometers are screwdriver-adjustable and easily accessed. Remote Programming: Two independent 0 to 5Vdc inputs for 0 to maximum voltage and current outputs. Accuracy is ±(0.2% of setting + 0.2% of maximum). The programming input impedance is greater than 1M?. The program inputs are differential; this feature provides user-defined program voltage polarity and eliminates ground loops. Voltage Monitor: 0 to +5Vdc proportional to 0 to maximum output high voltage. Accuracy is ±(0.2% of reading + 0.2% of maximum). The monitor output impedance is 10k? ±1%. Current Monitor: 0 to +5Vdc proportional to 0 to maximum output current. Accuracy is ±(0.5% of reading + 0.2% of maximum). The monitor output impedance is 10k? ±1%. Enable: TTL compatible. Remote “high” signal disables high voltage, remote low enables high voltage. The enable input must be pulled low to allow operation of high voltage regardless of whether supply is in local or remote mode. Operating Temperature 0°C to +50°C Storage Temperature: -40°C to +85°C Humidity: 20% to 85% RH, non-condensing Input Line Connector: IEC320 EMI filter/input connector, a detachable line cord is provided Interface Connector: 25 pin “D” connector, a mating connector is provided
