CONSNANT Wall Mount Static Var Generator (SVG) is a revolutionary modular three-level inverter reactive power management unit with compensation current ranging from 50A to 200A (50/75/100kVar capacity). It supports 3-phase 3-wire (3P3W) and 3-phase 4-wire (3P4W) wiring systems. The standard rated voltage is 400VAC, with optional 220VAC & 690VAC, compatible with 50Hz/60Hz power grids.
Designed with compact wall-mounted cabinet, the unit adopts full digital DSP+FPGA dual-core control system and high-frequency IGBT three-level NPC topology. It dynamically and synchronously solves reactive power surplus, three-phase unbalance, voltage fluctuation & flicker, and 2nd–13th harmonic distortion. It provides continuous bidirectional compensation for inductive and capacitive loads without over-compensation or under-compensation, stabilizing power factor above 0.95 up to 0.99.
Superior to traditional capacitor banks and 2-level SVG, this series features better harmonic offset performance, minimal thermal loss and ultra-fast response. Ideal for space-limited sites with nonlinear loads, including rail transit, petrochemical, mining, data center, EV charging stations and more. Rack-mounted SVG modules are available as alternatives, supporting parallel expansion.
Features:
Equipped with IGBT modules with switching frequency up to 35KHz, adopting 3-level NPC topology. Output current waveform is close to ideal sine wave, achieving far better harmonic suppression than conventional 2-level inverters. Max efficiency reaches 97.5% with ultra-low thermal loss.
Dual DSP+FPGA processor architecture: single-step response time ＜50μs, total system response ＜5ms. Instant adjustment against sudden load changes, eliminating over/under compensation completely.
Integrated 4 core functions: reactive power compensation, 3-phase unbalance correction, voltage regulation & flicker suppression, 2–13 times harmonic filtering. Customizable compensation priority with combined PF balancing & harmonic filtering modes.
Spacious independent air duct design with forced fan cooling, IP20 protection grade. Standard RAL7035 grey cabinet with customizable color. Compact wall-mounted layout saves floor space for small distribution rooms & server rooms.
Max. 5 units parallel operation by default (customizable for more sets). Standard RS485 communication for remote monitoring & data upload; built-in digital input and relay alarm output terminals.
Stable performance under wide temperature, voltage and current range. Standard altitude limit ≤1000m, derating solution available for high-altitude projects. Fully compliant with complete IEC international power quality standards.
