Programmable Electronic Load

SPL series electronic loads are high-precision direct current sinks for use in research, product development, production, service and vocational training.

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 in Deatail

High levels of operating safety thanks to safety functions and special functions

A multitude of protection and additional functions have been integrated, 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 reversal
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 sequential test 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 activated automatically when the instrument is switched on.
SCPI support makes it easy to set up an automatic test equipment system (ATE) which communicates with other programmable devices via the RS 232 port or the optional GPIB interface.

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.

Note:

Maximum continuous power available is derated linearly from 100% of maximum at 40 °C, to 75% of maximum at 55 °C.
Conductance (S) = 1 / Resistance (Ω)
The set level is 10 times larger than the slew rate in CCL mode.
The actual transition time is defined as the time required for the input to change from 10% to 90% or from 90% to 10% of the programmed excursion.
Transient frequency depends on the time for high/low level and rising/falling edge.
Full remote control via RS 232 with optional GPIB
