Normal mode voltage: <0·4mVrms and 2mVp-p (15V, 30V & 60V O/Ps)
<0·6mVrms and 2mVp-p (6V O/P)
Normal mode current: <0·2mArms; <40µArms Low I range (15V,
30V & 60V O/Ps).
<0·6mArms; <100µArms Low I range (6V O/P).
Common mode current: <5µArms
For any load change, measured at the output terminals, using
remote sense:
Voltage <(0·01% + 2mV).
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% + 500µA).
Voltage <(0·01% + 2mV) for 10% line change.
Current <(0·01% + 250µA) for 10% line change.
Voltage: typically <(50ppm + 0·5mV)/°C
Current: typically <(100ppm + 1mA)/°C;
<(100ppm + 0·1mA)/°C on 500mA range.
Output will withstand forward voltages of up to 20V (10V on 6V O/P)
above 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: 10mV and 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 10mV, 15/30/60V O/P's; 1mV, 6V O/P.
Accuracy ± (0·1% of reading + 10mV) 6/15/30/60V O/Ps
Resolution 1mA; 0·1mA on Low I range.
Accuracy ± (0·3% + 3mA) to 3A, ± (0·5% + 3mA) to 6A;
± (0·3% + 3mA) to 8A, ± (0·3% + 3mA) on Low I range, 6V
O/P
Selects a 2s time constant (normally 20ms) for averaging of rapidly
varying load currents.
Each output is fully independent and isolated. Operation is equivalent to
two single power supplies.
The two outputs remain isolated but the Slave voltage controls are
disabled and the Slave voltage is set equal to the Master voltage.
Slave voltage = Master voltage ±(0.1% of Master voltage ±10mV).
As tracking but the Slave voltage controls set an output voltage between
0% and 101% of the Master voltage. Once set, varying the Master voltage
