Summarize 1）Delay output: After the power supply is connected, there will be a time delay for 5-8s before operation; 2）Over and under voltage protection: If the output voltage is more than ±10%(±2%) higher/lower than the rated output value, the alarm gives off automatically and the power supply is cut automatically; 3）Over current and short circuit protection: When the set current is exceeded or short circuit is caused by over load, the power switch will trip out automatically; 4）Phase absence protection: Audible and visual alarm will be sent when phase absence exists and the power will be cut automatically; 5）Automatic inspection and diagnostic function: When hardware fails, the microprocessor will diagnose and send audible and visual alarm automatically; 6）Power network bypass function: When the voltage of electric network changes within ±4% of the rated voltage, the stabilizer will stop operation automatically except the microprocessor. Power network bypass function is enabled. 7）Double bypass function of commercial network: If the hardware fails or the fuse blows out and the voltage of electric network changes within 10% of the rated voltage, the power of stabilizer will be supplied under automatic bypass status; the “electric supply/voltage stabilization” bypass switch may be used to switch to commercial network bypass status manually under such condition. 8）Automatic temperature control function: When the temperature of the coil of isolating transformer exceeds +70℃, the automatic temperature controller will active the ventilation and heat emission function automatically. 9）Applicable load: Applicable to any load; 10）Anti surge property: A high performance surge shock suppressor is installed at the line input end to effectively eliminate fatal shock to equipment from pulse spike voltage within 10us-100us such as lightning induction.

Using condition

Using condition
ZSBW and ZDBW series stabilizer should be used indoors be indoors, normal conditions are as follows:
①Environmental temperature: -15℃~+55℃;
②Sea level elevation: 4000m
③Relative humidity: 10%RH~90%RH
④Installation position: no such materials serious effects on the Insulation of stabilizer, as gases, steam, chemical deposition, dust, dirt, and other explosive and erosive medium;
⑤There is no serious fluctuation in installation position;
⑥If any of above conditions are not satisfied, it is suggested that user and WENLIDA arrange the installation.
