GRANKIA GLT3320 transformer based industrial online 3 phase ups 20kva can deliver robust and reliable power protection for critical applications. Engineered with advanced double-conversion technology and an integrated isolation transformer, it ensures maximum reliability, safety, and compatibility with industrial loads.
The industrial online 3 phase ups delivers 20 kVA of continuous output power. It provides high-availability power protection for manufacturing lines and automation controllers. It also protects process equipment, server rooms, and communications infrastructure. Clean, reliable three-phase power is essential in these areas.
3 Phase UPS 20kVA Features
Topology
Online double-conversion for continuous isolation between input power and load.
Transformer-based design
Input/output isolation transformers for superior electrical isolation, improved surge/lightning protection, and better tolerance of harsh industrial environments.
Input compatibility
Wide input voltage range and high overload capability to handle voltage sags, swells, and unbalanced three-phase input conditions common in factories.
Output quality
Tight voltage regulation (±1% typical), low total harmonic distortion (THD < 3% with linear loads), and configurable output voltage/frequency for regional compatibility.
Battery system
External battery cabinet support with scalable runtime; intelligent battery management and temperature-compensated charging extend battery life.
Redundancy and parallel capability
Support for N+1 parallel configurations (optional) to increase availability or capacity.
Protection features
Overload, short-circuit, over-temperature, input phase loss, input phase reversal detection, and surge protection.
Operational Benefits
Continuous clean power
Double-conversion isolates loads from grid anomalies—ideal for sensitive control electronics.
Improved safety and surge handling
Transformers add galvanic isolation and better transient/surge tolerance common in industrial environments.
Serviceability
Bypass configurations and modular components reduce mean time to repair and enable hot maintenance.
Integration-ready
Standard digital and dry-contact interfaces support remote monitoring, alerting, and facility control systems.
