Product Introduction - Saelig AFV Series Manual

The AFV series power supply is a programmable power supply for grid simulation. With
advanced SPWM technology and direct digital frequency synthesis (DDS) waveform technology, the
power supply has stable output frequency and good continuity. AFV series power supplies provide
continuous, pure and stable sinusoidal voltage. They can achieve local control via remote control
through the user's PC using internal control and communication modules. The internal electronic
circuit can quickly detect over- current, overload, over-voltage and output short circuit, and will
automatically protect and cut off the output and sound an alarm. The integrated laminated busbar
technology and modular configuration in the power supply inverter unit improve reliability and
stability. The touch screen display and control make for easier operation.
The main performance characteristics of the AFV series variable frequency power supplies
are as follows:
Advanced SPWM technology and direct digital frequency synthesis (DDS) waveform

technology are used. The power supply has stable output frequency and good
continuity;
The patented inner loop energy-saving test design is used to reduce energy consumption;

High precision settings and output;

Comprehensive and stable protection, perfect self-diagnostic maintenance function

and higher system reliability;
The laminated busbar structure is used to effectively reduce the inductance of the

inverter circuit and improve the reliability of the inverter;
Intelligent fan speed regulation control is used with a built-in dust filter to achieve efficient

heat dissipation and effective protection in harsh environments;
Communication interface: Communication using RS485 (standard configuration)

and Ethernet (optional configuration);
A running event recording function records up to 255 events.
