KONSTANTER SPL Series

Programmable Electronic Load

Applications

Series SPL electronic loads are high precision direct current sinks

for use in research, product development, production, service

and vocational training.



The devices are distinguished by a diverse range of functions and

excellent regulating accuracy, as well as outstanding ease of

operation.

Features

High levels of operating safety thanks to safety functions and special

functions

A multitude of protection and additional functions have been inte-

grated, for example:

• Limiting of the setting ranges for voltage and current

with adjustable response delay and reaction

• Overcurrent protection (OCP)

• Overvoltage protection (OVP)

• Power limiting

• Overtemperature protection

• Protection of the electronic load in the event of polarity rever-

sal

• A highly effective, intelligent cooling system reduces system

temperature and results in increased power density.

• The input connector terminals are especially well suited for

large test current values.

Multifunctionality

• Equipped with 4 basic operating modes: CC, CV, CR, CP

• Rapid transient measurement of the connected device under

test with separate adjustment options for high/low level, rise

and fall time

• Extensive sequence functions (arbitrary functions) with 10 μs

as the smallest step rate and 100,000

s as the largest step

rate. Cyclical addresses can be freely selected and one

sequence can be combined with another, in order to create

even more complex test procedures.

• Short-circuit test, battery discharge test and other auxiliary

functions

• Remote sensor connector sockets and trigger connector

socket are included. The instrument is automatically switched

to sensing mode operation as soon as the remote sensors are

connected.

• 10 groups of parameter settings can be saved to memory,

and the default settings stored to RAM (location 0) are acti

vated automatically when the instrument is switched on.

• SCPI support makes it easy to set up an automatic test equip-

ment system (ATE) which communicates with other program-

mable devices via the RS 232 port or the optional GPIB inter-

face.

Easy Operation

• Easy-to-configure sequence parameters in combination with

extensive sequence editing functions

• Complete electronic calibration is possible without removing

the slide-in unit.

• 4 operating modes: constant current, constant voltage, 

constant load, constant power

• High speed sequence and transient measurement, short-cir-

cuit proof, battery discharging and other auxiliary functions

• Programmable current rise and fall time, steep edges

• Several groups of parameters (device settings) and sequences

(load profile) can be saved and retrieved.

• Floating power input / no grounding

• Safe electrical separation

• Input can be switched on and off.

• Voltage or current control is possible with constant power.

• Settings selected by means of rotary switch and keypad

• Multifunctional LCD panel

• Safety functions, amongst others adjustable power limiting

•Benchtop instrument, also suitable for mounting to a 19" rack
