Functionality and Control Panel
The stabilizer's microcontroller constantly analyzes input and output voltage and, using 16 regulation steps, precisely maintains the nominal voltage of 220 V, which helps protect connected equipment from failure due to power surges. The front panel features a digital indicator, LED parameter indicators, and a mode selection button. Pressing the button changes the information on the display cyclically in one direction: Input Voltage → Output Voltage → Power. LEDs show which parameter is displayed on the indicator.
Package Contents and Preparation for Use
Package contents: passport, stabilizer, box. Before connecting to the mains, always ensure that the power cable has no external damage and that the socket is grounded. Do not connect the device to an ungrounded socket! Plug the load into the socket on the back of the stabilizer, connect the device to the mains, and turn it on with the switch. After a delay of approximately 5 seconds, if there are no emergency situations and the mains voltage is within normal limits, the stabilizer will pass power to the load. Use the button on the front panel to select the desired parameter display on the indicator.
This STAB 0.25 relay stabilizer is optimally suited for protecting household electronics, computer equipment, low-power medical equipment, and other sensitive apparatus where voltage stabilization and protection against peak overvoltages are required.
