components of the system after the circuit breaker is switched on. The system
can only be switched on via the main switch after a positive check.
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).
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, provide 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.
Internal fans are responsible for cooling the interior of the system. These are
integrated into each individual power stage. Ventilation slots for discharging
the exhaust air are located at the rear of the system.
All essential connections are also located on the rear side of the system, as
shown in the following image.
Depending on the specification and function, following models are available:
STD – Standard Cabinet
SDC – Standard Cabinet with DC power source
ST2 – Standard Cabinet with Increased Safety
SD2 – Standard Cabinet with DC power source and Increased Safety
