The DC supply operates as a flexible output stage with a constant power characteristic (autoranging), and a wide voltage, current and power range. To achieve higher power and current all units are equipped with a master-slave bus. This enables up to 64 parallel con­nected devices to be combined into one system which can provide up to 1920 W and 64000 A. Such a system works as a single unit and can use different power classes, only the voltage class must remain constant. In this way a user can construct a 75 kW system from two 30 kW and one 15 kW devices from the PS 10000 range. Furthermore, typical laboratory functionality is provided.

True Autoranging

All 10000 series devices offer true autoranging capabilities. Autoranging allows the device to deliver a higher voltage at lower currents and a higher current at lower voltages than a power supply or load with a conventional square wave output/input characteristic. 

Power supplies and loads with autoranging provide users with a wider range of voltages and currents without having to oversize the devices. Benefits: For use in a variety of test applications, a single device provides a wider range of test applications and versatility.

AC Connection

The DC power supplies in the PS 10000 series are equipped with an active PFC which provides high efficiency at low energy consumption. Furthermore, the devices in this series provide a wide input voltage range. This extends from 1-phase 110/120 V up to 240 V AC mains supply and 3-phase 208 V to 380 V, 400 V, and 480 V AC mains supply. The devices can be operated in the majority of global mains supply. They adjust automatically, without additional configuration, to the available supply. In a 110/120 V and 208 V AC grid, a derating of the output power is set.

DC Output

The output of the bidirectional power supply PS 10000 with a DC voltage of 0 - 60 V up to 0 - 2000 V allows currents of 0 - 6 A up to 0 - 1000 A. The flexible output stages (autoranging) provide the user with a wide voltage, current and power range and hence a wider field of working than traditional power supplies.

DC Connection

Connection of the DC output is via a copper rail on the back side of the device. If a system with higher performance is required. the devices are simply connected in parallel. With minimal effort devices can be linked with the vertical copper rails. A cover for contact protection is provided.
