Safety and Regulatory Notices
Using the system can cause danger and damage for life and limb of the
operators or third parties, to the system itself or to other material assets.
In addition to the manufacturer´s countermeasures, the operator must also
take appropriate countermeasures against danger due to residual energy.
The personnel must be briefed about these dangers and the necessary
countermeasures during instruction.
The following general safety precautions must be observed during all
phases of operation of this instrument. Failure to comply with these pre-
cautions or with specific warnings or instructions elsewhere in this manual
violates safety standards of design, manufacture, and intended use of the
instrument. Keysight Technologies assume no liability for the customer´s
failure to comply with these requirements. Please read the also the section
Intended Use.
Danger to life in case of misuse at the outputs.
The Scienlab Regenerative AC Emulator does not have its own insulation guard.
If the system emulates an electrical isolation against PE at the output, the lo-
cal installation regulations and guidelines must be observed.
This would be in the case of the emulation of an IT network in AC mode, or
generally in DC mode.
Danger to life due to high voltages.
Some components are still supplied with voltage after switching off (wiring color
orange).
Before installation and maintenance work, turn off and lock out all external
voltage supplies.
Only disconnect or establish electrical connections in a voltage-free condition.
Danger to life due to missing covers!
In case of misapplication, missing protective cover can lead to severe injury,
burns or death in the event of shock and arc flash.
Do not remove cover under load and not operate without cover in place.
After installation and maintenance work, the previously removed protective
cover must be replaced.
Depending on the set output voltage and current, the system sometimes releases
large amounts of energy at the output.
Touching the connection bars inside the system or the DUT terminals can occur
life-threatening body currents.
Never touch, connect, or disconnect the connecting lines to the DUT during
active operation.
Danger of arcing.

Residual voltage after switch-off.
In case of connected DUT, the output terminals can still carry voltages even after
switch-off of the system!
Measure the voltage at the outputs to ensure that they are voltage-free.
Danger to life due to charging or discharging batteries.
Batteries are sensitive to overloading/underloading and might explode or start
burning. This can lead to danger for life and limb.
Therefore, a battery must be monitored by a battery management system
(BMS).
Hearing protection due to noise exposure in the operating area!
Noise level < 85 dB(A) at a distance of 1 m from the front
It is recommended to wear hearing protection during operation.
Safety and Monitoring Devices
The system has monitoring devices that switch-off the system in case of
emergency. If additional systems are connected to the SL1200A Scienlab
Regenerative AC Emulator, it is recommended that the systems are inte-
grated into a higher-level safety device.

System Description 1
Functional Description
The SL1200A serves as a regenerative, bi-directional, 3-phase AC
source/sink, with optional DC source/sink. The system can be parameter-
ized in voltage- or current-controlled mode (Voltage Priority or Current
Priority). The system was given a compact design with integrated measur-
ing and is available as Low-Voltage (600 V, model SL1201A –SL1203A) or
High Voltage (1200 V, model SL1212A –1213A) variant, depending on the
respective application.
The SL1200A consists of three (45 kVA) or six (90 kVA) power stages (RPS
–regenerative power system), there are two different types of power
stages, low voltage (600 V AC, optional 500 V DC) or high voltage
(1200 V AC, optional 1000 V DC). The power stages can be parametrized
and used individually or together with each other. Thus, various configura-
tions are possible.
In AC mode, the SL1200A is operated with a sinusoidal AC voltage output
and an adjustable basic frequency of 40 to 75 Hz. This enables the opera-
tor to supply 1-, 2- or 3-phase consumers, and test them in operation by
means of targeted error emulation (Voltage Priority). If the SL1200A is
configured in Current Priority mode, the power stage synchronizes with
the voltage measured at the terminals and regulates the specified (positive
or negative) current.
The following table shows examples for AC grid emulations.

Table 2: Examples for emulated AC grids
Equipped with an optional DC mode, the SL1200A can be operated as a
Voltage Priority with different output voltages. If, for example, a charging
station is tested, the system can be used to emulate the HV battery in the
vehicle (Current Priority). If, instead, the vehicle with a battery is tested,
the SL1200A can emulate a DC charging station (Voltage Priority). If a
battery is connected to the SL1200A, the battery must be monitored by a
battery management system (BMS). The outputs at the DC mode are al-
ways electrically isolated against ground (PE).
The system features two separate current paths, the power path and the
logic path. The main switch uses the power path to disconnect the power

stages and the grounding conductor interconnections from the mains. In
the event of an emergency stop, the main switch switches the output to a
safe condition.
Figure 1: Two current paths of SL1200A
When switching the system off via the main switch, some components
connected in the logic chain (e. g. measurement and control unit (MCU),
switch and safety relay) are not switched off by the supply disconnecting
device and continue to be supplied with voltage (lines marked orange) to
maintain communication between system and operating software, even in
the event of an emergency stop. The logic path can be switched off via the
service switch (service switch/circuit breaker for motor protection). This
switch is located on the front behind the detachable panel. When the logic
path is switched off, the power path cannot be switched on.
Via the customer interface, the system can be configured as either a 1- to
3-phase AC source/sink or a DC source/sink (DC optional, -SDC option).
Channel switchover between AC and DC operation may only be performed
in load-free state. AC and DC operation use separate terminal blocks (DC
terminals only on -SDC option) (see documentation Getting Started
Guide).
System Arrangement
The SL1200A consists of two rack variants with three or six power stages;
both rack variants are available as low-voltage and high-voltage. The low-
voltage variants SL1201A –SL1203A are designed with an output voltage
of up to 600 V, an output current of up to 125 A, and an output power of
up to 90 kVA. The high-voltage variants SL1212A –1213A, however, pro-
vide an output voltage of up to 1,200 V, an output current of up to 65 A,
and an output power of up to 90 kVA.
Communication to both a control computer and the parallel-connected
systems is ensured by Ethernet interfaces.
