Summary of Contents for Himel HTND2 Series

  • Page 1 HTND Series User Manual Please carefully read the user manual before the installation and use of the products,and then keep it properly as backup.
  • Page 2 High Precise Full-Automatic AC Voltage Stabilizer Overview 1. HTND series is a new developed LED display AC voltage stabilizer based on HTND. It is controlled by CPU, while it has elegant appearance, wide range for stabilizing voltage and no additional distortion. Overvoltage protection and short circuit protection are included in HTND (undervoltage protection and time-delay selection can be customized).

Input of the stabilizer is 1. Power on the input power and Voltage stabilizer is out open circuit; check whether the wiring is solid and of work and no output 2.

  • Page 14: Installation Tips

    Installation Tips Proper external wiring conductive lines are selected according to load power or rated power of voltage stabilizer before installation. Input and output conductive lines for external wiring is not recommended to be too thin or too long to cause abnormal work. External wiring conductive lines can be selected as follows: As calculation of a standard current-carrying capacity for a copper conductor: the safe current-carrying capacity...
