The AF10 is available in three variants.
While the basic version offers basic PWM functionality, the automation variant has an interface to remotely control the PWM generator as well as a ramp function to output programmable duty cycle characteristics.
Finally, the engineering variant allows external power modules of different topologies to be connected and controlled via the extension interface.

Devices already purchased can be upgraded to a higher variant at any time by means of an activation key, which you can obtain from us on request. The device does not have to be sent in for this purpose.

The AF10 is a highly flexible PWM generator for laboratory and test stand use.

Its output operates in a voltage range from 3 to 24 V and is low-resistance, so that it can deliver currents up to 1 A. This distinguishes it significantly from conventional function gen­erators. If the output power of up to 24 W is insufficient, it can be increased to higher output voltages and currents using power modules available as an option.

The interface to external power modules is disclosed and documented, so that the user can very easily develop and operate his own modules.

A ramp function makes it possible to output freely programmable PWM traces, whose duty cycle, frequency and amplitude can be modulated. A detailed description of this func­tion is given in a separate article:

Advanced ramp functions

For test stand operation, the AF10 has further essential characteristics besides the ramp function:

  • Optional 8/24 open drain outputs to control 8/24 test pieces
  • Galvanically separated SPS interface for remote control of the duty cycle
  • Optional galvanically separated RS232 interface for remote control of duty cycle, frequency and voltage
  • Restart of the last function after an interruption in power supply
  • . . .

In laboratory operation the AF10 can be used for the most varied development and analysis scenarios. An incomplete list of possible use scenarios is given in the following separate article:
Application examples for the AF10 PWM generator

Based on the AF10 we develop customized PWM generators and laboratory devices to control for example actuators, solenoid valves, active chassis components, electromagnets, or also any other applications.
