ZSBD/ZDBW stabilizer

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 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.
