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 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
Accuracy ± (0·1% of reading + 10mV)
Resolution 1mA; 0·1mA on 500mA range.
Accuracy ± (0·3% + 3mA) to 3A, ± (0·5% + 3mA) to 6A;
± (0·3% + 0·3mA) on 500mA range.
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
will create the same percentage change in the Slave voltage setting.
% change in Slave voltage = % change of Master voltage ± 0.1% ±10mV.
The Master output operates as a single output power supply with twice
the current capability (0.2mA to 6A). The Slave is disabled (and its
displays are turned off).
Each output has an independent DC On/Off control; these additional keys
can be used to turn both outputs on or off simultaneously. These keys
operate in all four modes.
