The STEVAL-GLA001V1 evaluation board allows insulated control of three AC loads up to 1 kW (230 Vrms) with Triacs and AC switches (instead of relay solutions), particularly suitable for residential appliances.
The board must be controlled with an STM32 microcontroller embedded on an NUCLEO-F030R8 STM 32 Nucleo development board, or other microcontroller supplied by the user.
If you are using an STM32 Nucleo development board, three AC switch control modes are available for load control: continuous or pulse gate current, timer option and phase control. The STSW-GLA001V1 firmware is available for free download and easily programmable through a PC interface on a USB bus. The main parameters can be adjusted through a common interface like HyperTerminal, without needing to edit the MCU firmware.
The hardware is designed to offer a wide input voltage range, low standby power losses, IEC61000-4-4 robustness and two low voltage power supplies.
