Operating Modes

The devices have constant-current and constant-resistance operating modes in both static and dynamic operation. If fitted with an RS-232 or GPIB interface, software-controlled constant power control is possible. The manual setting of the load values takes place via two precise ten-turn potentiometers. Switch from value A to value B by a keystroke.

Dynamic Operation

In dynamic mode the inbuilt modulator performs the switch between the setpoints A and B. For each load level it is possible to set a corresponding pulse duration of 0.5 ms … 500 milliseconds. In addition, pulse-pause ratios can be varied within broad time range. Switching between the two load levels can also be via the Analog I/O Interface at all levels between 3 V and 30 V.

Interfaces (optional)

• RS-232 + system bus
• GPIB + RS-232 + system bus
• Smart-LAN (Ethernet-RS-232-Converter)
