Liebert Hipulse D Ups Manual Jun 2026
The Liebert Hipulse D UPS is a modular, three-phase UPS system that uses advanced power conversion technology to provide high efficiency and reliability. The system consists of a rectifier/inverter module, a battery module, and a control module. The rectifier/inverter module converts AC power to DC power and then back to AC power, while the battery module provides energy storage for backup power. The control module monitors and controls the system, ensuring seamless transitions between normal and backup power modes.
Operating the Hipulse D requires familiarity with its user-friendly LCD and mimic panel. According to technical documentation, here are the primary controls you should know:
Standard 415V AC (3-phase) input, with single or 3-phase output options. Efficiency: Typically exceeds 95% in normal operation. 2. Installation Guidelines
Look for a silver rating plate on the door. The correct SKU (e.g., Hipulse D 100-400V-6P) will direct you to the right document.
Rotate the manual (often designated as Q3 or MBS) from the "OFF" to the "ON" or "BYPASS" position. Open the Inverter Output Switch and Main Input Switch . liebert hipulse d ups manual
Built-in inverter output isolation transformer protects the load from DC bus anomalies and utility disturbances.
Close the . The system logic control will initialize.
The Hipulse D is engineered for robust electrical performance with high fault tolerance. Standard Offering 5 kVA to 160 kVA Input Voltage 415 V AC, 3 Phase, 3 Wire (+10%, -20%) Input Frequency 50 Hz (± 10%) Output Voltage 220V/230V/240V AC (1P) or 400V/415V AC (3P) THD (Voltage) < 2% for 100% Linear Load Overload Capacity 110% for 60 min; 125% for 10 min; 150% for 1 min 2. Advanced Features & Benefits
During standard operation, utility AC power enters the rectifier, turns into DC, and is converted back to AC by the inverter. This double-conversion process filters out voltage spikes, frequency variations, and harmonic distortion. Battery (Emergency) Mode The Liebert Hipulse D UPS is a modular,
Close the . The rectifier will start up automatically (indicated by a ramping DC bus voltage). Turn on the external Battery Bank Circuit Breaker .
The system supports a wide range of battery types (VRLA, Lead Acid, Ni-Cd, and Li-Ion) and includes temperature-compensated charging to optimize battery lifespan. Ease of Maintenance: The mechanical assembly is designed for front access
