Operating Modes

The ZSLC series electronic loads have the four operating modes constant current, voltage, power and resistance. In addition, depending on the operating mode limit values can be set for the maximum permissible current and the minimum permissible voltage.

To increase the resolution for each device, along with the full setting range, a reduced setting of 1/3 of the rated current is available. The load can be preset even without a connected test unit. The display then shows the values directly in amps, ohms, volts or watts.

Dynamic and Control Time

The inbuilt modular enables two independently-adjustable currents and times from 100 μs ... 1 s. The control speed of the devices can be adjusted to the test unit in three stages (fast - medium - slow).

Interfaces (optional)

  • RS-232 + USB
  • GPIB
  • Smart-LAN (Ethernet-RS-232 Converter)
  • System Interface Cabel or Fiber Optic
  • Data Acquisition Tool
