HYDVR series Voltage Sag Mitigation Solution for Sensitive Industries

HYDVR series Voltage Sag Mitigation Solution for Sensitive Industries

The HYDVR dynamic voltage restorer is designed to protect sensitive industrial loads from short-duration voltage sags and interruptions. Installed in series with the protected feeder, it detects an incoming voltage disturbance and injects the required compensating voltage within milliseconds, helping continuous-process equipment, automation systems and precision manufacturing remain in operation.

Model Description

HY DVR 04–300 H F N–040 C
  • C / A: Supercapacitor / Electrolytic capacitor
  • Protection time (s): e.g., 040 = 0.4 s
  • N: Three-phase four-wire (no N = three-phase three-wire)
  • F / B: Front access / Rear access
  • H / L: Top access / Bottom access
  • Rated protection capacity (kVA): e.g., 300 = 300 kVA
  • Voltage class (kV):
    • 02 = 208 V
    • 04 = 400 V
    • 06 = 600 V
    • 6 = 6 kV
    • 10 = 10 kV
  • DVR: Dynamic Voltage Restorer
  • Brand: Hongyan Electric
Notes:
  1. Protection time is a three-digit scientific notation, unit in seconds (s). For example, 363 = 3.6 × 10³ s (≈1 hour), 040 = 0.4 s.
  2. Rated protection capacity range: 30–5000 kVA (see technical parameters table).
