OUTPUT SPECIFICATIONS |
Output Setting & Control |
Voltage Setting |
By coarse and fine controls |
Current Setting |
By single logarithmic control |
Output Mode |
Constant voltage or constant current with automatic cross-over
CC indicator lit in constant current mode |
Output Switch |
Electronic, non isolating. Preset voltage and current limit displayed when Output is off. Output rise time no load <15ms |
View Settings |
With the output On, the meters show actual voltage and current.
The preset levels can be viewed and adjusted at any time by pressing the View Settings button. |
V-Span * |
(Voltage Span Control)
The voltage adjustment range can be controlled by digital setting of the end-stop values of the coarse voltage control to any desired values. The range for Vmax is 0.1V to 15V/30V/60V depending on model. The range for Vmin is 0 to (Vmax – 0.1V). |
S-Lock |
(Settings Lock)
Voltage and current settings can be locked by a single button press. Lock accuracy is equal to the meter accuracy (see Meter Specification). |
Output Performance |
Ripple & Noise * |
Normal mode voltage: <0·4mV rms and 2mV p-p
Normal mode current: <0·2mArms; <40uA on 500mA range.
Common mode current: <5uA rms |
Load Regulation |
Voltage - <0·01% + 2mV.
Current - typically 0·01% + 500µA. |
Voltage specification applies for any load change, measured at the output terminals. When using remote sense add 0.5mV per 0.1V drop in the +ve output lead (max. sense lead resistance 0.5 W). |
Line Regulation |
Voltage <0·01% + 2mV for 10% line change.
Current <0·01% + 250µA. for 10% line change. |
Transient Response |
<50µs to within 50mV of setting for a 90% load change. |
Temp. Coefficient |
Voltage: typically <(50ppm + 0·5mV)/°C
Current: typically <(100ppm + 1mA)/°C;
<(100ppm + 0.1mA)/°C on 500mA range. |
Output Protection |
Output Protection |
Output will withstand forward voltages of up to 20V above rated output voltage. Reverse protection by diode clamp for currents to 3A. |
OVP and OCP Trips |
Voltage or current measured to be in excess of 105% of the rated maximum will cause the output to trip off. |
Over-temperature |
Output trips off for over-temperature. |
Safety Interlocks |
Operations that could cause an unexpected change in voltage or current settings are interlocked with the output switch. |
Output Connections |
Output Terminals |
Universal 4mm safety binding posts on 19mm (0·75”) spacing. |
Terminals can accept fixed shroud 4mm plugs, standard 4mm plugs, fork terminals and bare wires. |
Remote Sense |
Sense Selection |
Voltage sensing is selected as Local or Remote by front panel switch. |
Sense Terminals |
Sprung loaded screw-less terminals. |
