Specification

General specifications apply for the temperature range 5°C to 40°C. Accuracy specifications
apply for the temperature range 18°C to 28°C after 1 hour warm-up with no load and calibration at
23°C. Typical specifications are determined by design and are not guaranteed.

screwless terminals for Sense.
Duplicate rear panel Output and Sense screw terminals on P models.

Transient Response:

<50

µs to within 15mV of set level for a change in load current from full

load to half load or vice versa.

Voltage Programming
Speed:

Maximum time required for output to settle within 1% of its total excursion
(for resistive load). Excludes command processing time.

Ripple and Noise
(20MHz bandwidth):

Normal mode voltage: <0·35mVrms and 2mVp-p
Normal mode current: <0·2mArms; <20

µArms on 500mA range.

Load Regulation:

For any load change, measured at the output terminals, using
remote sense.

Voltage <0·01% + 2mV.
Current <0·01% + 250µA; <0.01% +50µA on 500mA range.

Add typically 2·5mV for a 0·5V drop in the positive output lead.
Specification applies for sense lead resistance <0·5

Ω.

Line Regulation:

Voltage <0·01% + 2mV for 10% line change.
Current <0·01% + 250µA; <0.01%+ 50µA on 500mA range.

Temperature Coefficient:

Voltage:

typically <(50ppm + 0·5mV)/°C

Current:

typically <(100ppm + 1mA)/°C;

typically<(100ppm + 0·1mA)/°C on 500mA range.
