For any load change, measured at the output terminals, using
remote sense:
Voltage <(0·01% + 10mV).
Add typically 2·5mV for a 0·5V drop in the positive output lead.
Specification applies for sense lead resistance <0·5Ω.
Current typically <(0·01% + 50µA)
Voltage <(0·01% + 10mV) for 10% line change.
Current <(0·01% + 50µA) for 10% line change.
Voltage: typically <(50ppm + 2mV)/°C
Current: typically <(100ppm + 0.1mA)/°C;
<(100ppm + 0·01mA)/°C on 75mA range.
Output will withstand forward voltages up to rated output voltage. Reverse
protection by diode clamp for currents up to 3A.
Output trips off for over-temperature.
Measure-and-compare over-voltage and over-current protection are
implemented in firmware and can be set via the remote interfaces only.
Output trips off for OVP and OCP. Setting resolution: 100mV and 0.1mA.
Response time: typically 500ms.
For manual operation (Local mode) OVP and OCP are fixed at 105% of the
instrument range maximum.
Dual 4-digit meters, 10mm (0·39") LED.
Resolution 100mV
Accuracy ± (0·1% of reading + 100mV)
Resolution 0.1mA; 0·01mA on 75mA range.
Accuracy ± (0·3% + 0.3mA) ± (0·3% + 0·03mA) on 75mA range.
Selects a 2s time constant (normally 20ms) for averaging of rapidly varying
load currents.
Rear panel control inputs (CV and CC) permit external 0V to 5V or 0 to10V
signals (with respect to the common Return) to set 0 to 100% of rated
output voltage and current. Inputs are protected against excess input
voltages up to 60V. Isolation rating with respect to the output is 300V max.
Voltage: 0.3% ±200mV. Input impedance 10kΩ.
Current: 0.5% ±0.5mA. Input impedance 10kΩ.
Set values of 0 to 100% of rated output voltage and current generate 0 to
5V signals at the rear panel V
protected. These signals are referenced to the output control circuit and
will therefore be within ~1V of the positive output potential.
Voltage: 0.3% ±100mV
Current: 0.5% ±0.5mA.
Output impedance: 125Ω.
Rear panel connections allow a switch closure to turn output off. Remote
Off is referenced to the output control circuit and will therefore be within
~1V of the positive output potential.
