Description
Connecting several units in series adds up their output voltages, but each unit has its own insulation voltage limit relative to the housing. SCB monitors exactly this and protects the series-connected units against exceeding the permissible insulation voltage. The unit is designed for devices with an output voltage from 0–360 V to 0–1500 V. Two or three devices are connected in the chain, and the total system voltage lies within 1000–3000 V depending on the class of the devices. The accessory is intended for EA power supplies and electronic loads, so the bench is built from devices of the same type. Without such a unit, the top device in the chain would work with its insulation at the limit of what is permissible.
How to choose
The unit version is chosen for the rated voltage of the devices in the chain. The series consists of the models SCB 10360 B, 10500 B, 107250 B, 10920 B, 11000 B and 11500 B, and their designations correspond to device voltage classes from 360 to 1500 V. The number of devices, 2 or 3, is calculated from the required bench voltage, keeping in mind the upper limit of 3000 V. For a bench with two 1500 V sources, a voltage of about 3000 V is enough without a third device.

FAQ
What maximum voltage can be obtained with the SCB unit?
Depending on the devices in the chain, the system voltage is 1000–3000 V DC. The upper limit depends on the voltage class and the number of devices.
How many power supplies can be connected in series through SCB?
Two to three devices are connected in one chain. These can be either power supplies or EA electronic loads.
What does the source series connection unit protect against?
SCB keeps the voltage on a single device from exceeding the permissible insulation voltage that arises with series connection. This way the insulation of the devices is not overloaded.
Which devices is SCB compatible with in terms of voltage?
The series covers devices with an output voltage from 0–360 V to 0–1500 V. Each voltage class has its own unit version.
Where is series connection of sources through SCB used?
On test benches for rail transport, aviation and renewable energy, where a DC voltage above 1000 V is needed.
