Key Features:

  • Voltage up to 400
  • Currrent up to 150 A
  • Power 500 W ... 1,500 W
  • Short-time overload capacity
  • Current and resistance mode
  • Dynamic loads
  • SCPI programming with measurement function
  • Full electronic protection
  • Analog measurement output for voltage, current and power
  • Analog control input

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)
